1990 jeep wrangler bleeding breaks


Hi there:
I suggest to check this procedure, when the hydraulic brake system must be bled whenever a fluid line has been disconnected because air gets into the system.

A leak in the system may sometimes be indicated by a spongy brake pedal. Air trapped in the system is compressible and does not permit the pressure applied to the brake pedal to be transmitted solidly through the brakes. The system must be absolutely free from air at all times. If the master cylinder has been overhauled or a new cylinder has been installed, bleed the cylinder on a bench before installation. When bleeding brakes, bleed at the wheel most distant from the master cylinder first, the next most distant second, and so on. During the bleeding operation the master cylinder must be kept at least 3 / 4 full of brake fluid.


The ABS bleeding procedure is different from the conventional method. It consists of the following three steps:
Step 1: Conventional manual brake bleed.
Step 2: Bleeding the system using the DRB scan tool.
Step 3: An additional conventional manual brake bleed.

The recommended ABS bleeding procedure is as follows:
  1. To bleed the brakes, first carefully clean all dirt from around the master cylinder filler cap. Remove the filler cap and fill the master cylinder with DOT 3 brake fluid to the lower edge of the filler neck.
  2. Bleed the master cylinder first. Have a helper operate the brake pedal while bleeding each master cylinder fluid outlet line. Do not allow the master cylinder to to run out of fluid,as this will allow additional air to be drawn into the cylinder.
  3. Bleed the brake system in the following sequence:
    1. Master cylinder
    2. HCU valve body (at fluid lines)
    3. Right rear wheel
    4. Left rear wheel
    5. Right front wheel
    6. Left front wheel
  4. Clean off the bleeder connections at all four wheel cylinders. Attach the bleeder hose to the right rear wheel cylinder bleeder screw and place the end of the tube in a glass jar, submerged in brake fluid.
  5. Open the bleeder valve 1/2 - 3/4 of a turn.
  6. Have an assistant depress the brake pedal slowly and allow it to return. Continue this pumping action to force any air out of the system. When bubbles cease to appear at the end of the bleeder hose, close the bleeder valve and remove the hose.
  7. Check the level of fluid in the master cylinder reservoir and replenish as necessary.
  8. After the bleeding operation at each wheel cylinder has been completed, fill the master cylinder reservoir and replace the filler plug.

Do not reuse the fluid which has been removed from the lines through the bleeding process because it contains air bubbles and dirt.


  1. Perform the "Bleed Brake'' procedure with the DRB II scan tool. This procedure is described in the DRB II software information and diagnostic guide.
    1. Attach the DRB II scan tool to the diagnostic connector.
    2. Run the Bleed Brake procedure as described in the DRB II tester guide.
  2. Repeat the conventional bleeding procedure as previously outlined.
  3. Fill the master cylinder reservoir to the proper level.
  4. Check the brake operation.


Hope this helps.

How do I bleed brakes on a dodge stratus 1998


  • PRESSURE BLEEDING
  • MANUAL BLEEDING
  • Print
    For vehicles equipped with an Anti-lock Brake System (ABS), please refer to the ABS bleeding procedure at the end of this section.
    The purpose of bleeding the brakes is to expel air trapped in the hydraulic system. The system must be bled whenever the pedal feels spongy, indicating that compressible air has entered the system. It must also be bled whenever the system has been opened or repaired. If you are not using a pressure bleeder, you will need a helper for this job.

    WARNING Never reuse brake fluid which has been bled from the brake system.


    MASTER CYLINDER

    See Figure 1
    If the master cylinder is off the vehicle, it can be bench bled.

    1. Secure the master cylinder in a bench vise.
    2. Connect 2 short pieces of brake line to the outlet fittings, bend them until the free end is below the fluid level in the master cylinder reservoirs.
    3. Fill the reservoir with fresh DOT 3 type brake fluid.
    4. Using a wooden dowel, or equivalent, pump the piston slowly several times until no more air bubbles appear in the reservoirs.



    0900c15280089cdc.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Fig. 1: Attach bleeding tubes to the master cylinder and position them as shown

    1. Disconnect the 2 short lines, refill the master cylinder and securely install the cylinder cap.
    2. If the master cylinder is on the vehicle, it can still be bled, using a flare nut wrench.
    3. Open the brake lines slightly with the flare nut wrench, while pressure is applied to the brake pedal by a helper inside the vehicle.
    4. Be sure to tighten the line before the brake pedal is released.
    5. Repeat the process with both lines until no air bubbles come out.
    6. Bleed the complete brake system, if necessary.

    If the master cylinder has been thoroughly bled and filled to the proper level upon installation into the vehicle, it is not necessary to bleed the entire hydraulic system.


    PRESSURE BLEEDING

    When bleeding the brakes, air may be trapped in the brake lines or valves far upstream, as much as 10 feet from the bleeder screw. Therefore, it is very important to have a fast flow of a large volume of brake fluid when bleeding the brakes, to make sure all of the air is expelled from the system.
    On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Left rear wheel Right front wheel Right rear wheel Left front wheel
    On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Right rear wheel Left front wheel Left rear wheel Right front wheel

    1. You should use bleeder tank tool C-3496-B or equivalent, with the required adapter for the master cylinder reservoir to pressurize the hydraulic system for bleeding. Make sure to follow the manufacturer's directions for using a pressure bleeder.
    2. Attach a clear plastic hose to the bleeder screw located at the right rear wheel, then place the hose into a clean jar that has enough fresh brake fluid to submerge the end of the hose.
    3. Open the bleeder screw at least one full turn or more to get a steady stream of fluid.
    4. After about 4-8 oz. of fluid has been bled through the brake system and an air-free flow is maintained in the hose and jar, close the bleeder screw.
    5. Repeat the procedure at all the other remaining bleeder screws. Then, check the pedal for travel. If pedal travel is excessive or has not improved, enough fluid has not passed through the system to expel all of the trapped air. Be sure to monitor the fluid level in the pressure bleeder. It must stay at the proper level so air will not be allowed to re-enter the brake system through the master cylinder reservoir.
    6. Once the bleeding procedure is complete, remove the pressure bleeding equipment from the master cylinder.


    MANUAL BLEEDING

    See Figure 2
    Proper manual bleeding of the hydraulic brake system will require the use of an assistant.
    On Cirrus, Stratus, Sebring convertible and Breeze models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Left rear wheel Right front wheel Right rear wheel Left front wheel
    On Sebring coupe and Avenger models, the following wheel sequence should be used to ensure that all the air is removed from the system:


    Right rear wheel Left front wheel Left rear wheel Right front wheel

    Fig. Fig. 2: With a clear plastic hose in a container of clean brake fluid, open the bleeder screw at least one full turn

    1. Attach a clear plastic hose to the bleeder screw located at the right rear wheel, then place the hose into a clean jar that has enough fresh brake fluid to submerge the end of the hose.
    2. Have an assistant pump the brake pedal 3-4 times, and hold it down before the bleeder screw is opened.
    3. Open the bleeder screw at least one full turn. When the bleeder screw opens, the brake pedal will drop.
    4. Close the bleeder screw. Release the brake pedal only AFTER the bleeder screw is closed.
    5. Repeat the procedure 4 or 5 times at each bleeder screw, then check the pedal for travel. If the pedal travel is not excessive, or has not been improved, enough fluid has not passed through the system to expel all of the trapped air. Make sure to watch the fluid level in the master cylinder reservoir. It must stay at the proper level so air will not re-enter the brake system.
    6. Test drive the vehicle to be sure the brakes are operating correctly and that the pedal is solid.

    Brake issue.... turn left till steering pulses and brakes go to floor, and master cylinder bubbles... what would cause that. I bleed all brakes and all good, then random turn or out of the blue no...


    It sounds like you have a faulty Electro-Hydraulic Control Unit (EHCU) or a Brake Pressure Modulator Valve (BPMV). Air is trapped in the valve body and air is much harder to get out of the master cylinder than it is the lines. You can try this method to help troubleshoot.

    This is out of the Online GMsevice manual for a 2001 Blazer with 4-WD
    Use the two-person bleed procedure under the following conditions:

    Raise the vehicle in order to access the system bleed screws.
    Bleed the system at the right rear wheel first.
    Install a clear hose on the bleed screw.
    Immerse the opposite end of the hose into a container partially filled with clean DOT 3 brake fluid.
    Open the bleed screw 1/2 to one full turn.
    Slowly depress the brake pedal. While the pedal is depressed to its full extent, tighten the bleed screw.
    Release the brake pedal and wait 10-15 seconds for the master cylinder pistons to return to the home position.
    Repeat the previous steps for the remaining wheels. The brake fluid which is present at each bleed screw should be clean and free of air.
    This procedure may use more than a pint of fluid per wheel. Check the master cylinder fluid level every four to six strokes of the brake pedal in order to avoid running the system dry.
    Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure . Release the brake pedal between each test.
    Bleed all four wheels again using Steps 3-9. This will remove the remaining air from the brake system.
    Evaluate the feel of the brake pedal before attempting to drive the vehicle.
    Bleed the system as many times as necessary in order to obtain the appropriate feel of the pedal.

    Good luck, i hope this helps.

    Need to know procedure for bleeding brakes on1987 gmc s15 2.8 litre 4x4 front disc w/abs


    MANUAL BLEEDING

    For those of us who are not fortunate enough to have access to a power bleeding tool, the manual brake bleeding procedure will quite adequately remove air from the hydraulic system. The major difference between the pressure and manual bleeding procedures is that the manual method takes more time and will require help from an assistant. One person must depress the brake pedal, while another opens and closes the bleeder screws.

    In addition to a length of clear neoprene bleeder hose, bleeder wrenches and a clear bleeder bottle (old plastic jar or drink bottle will suffice), bleeding late-model ABS systems may also require the use of one or more relatively inexpensive combination valve pressure bleeding tools (which are used to depress one or more valves in order to allow component/system bleeding). To fully bleed the late model ABS systems, a scan tool should also be used to run the system through functional tests.
    1. Clean the top of the master cylinder, remove the cover and fill the reservoirs with clean fluid. To prevent squirting fluid, and possibly damaging painted surfaces, install the cover during the procedure, but be sure to frequently check and top off the reservoirs with fresh fluid.
    CAUTION Never reuse brake fluid which has been bled from the system.
    1. The master cylinder must be bled first if it is suspected to contain air. If the master cylinder was removed and bench bled before installation it must still be bled, but it should take less time and effort. Bleed the master cylinder as follows:
      1. Position a container under the master cylinder to catch the brake fluid.
    WARNING Do not allow brake fluid to spill on or come in contact with the vehicle's finish as it will remove the paint. In case of a spill, immediately flush the area with water.
      1. Loosen the front brake line at the master cylinder and allow the fluid to flow from the front port.
      2. Have a friend depress the brake pedal slowly and hold (air and/or fluid should be expelled from the loose fitting). Tighten the line, then release the brake pedal and wait 15 seconds. Loosen the fitting and repeat until all air is removed from the master cylinder bore.
      3. When finished, tighten the line fitting to 20 ft. lbs. (5 Nm).
      4. Repeat the sequence at the master cylinder rear pipe fitting.
    During the bleeding procedure, make sure your assistant does NOT release the brake pedal while a fitting is loosened or while a bleeder screw is opening. Air will be drawn back into the system.
    1. Check and refill the master cylinder reservoir.
    Remember, if the reservoir is allowed to empty of fluid during the procedure, air will be drawn into the system and the bleeding procedure must be restarted at the master cylinder assembly.
    1. On late model ABS equipped vehicles, perform the special ABS procedures as described later in this section. On 4 wheel ABS systems the Brake Pressure Modulator Valve (BPMV) must be bled (if it has been replaced or if it is suspected to contain air) and on most Rear Wheel Anti-Lock (RWAL) systems the combination valve must be held open. In both cases, special combination valve depressor tools should be used during bleeding and a scan tool must be used for ABS function tests.
    1. If a single line or fitting was the only hydraulic line disconnected, then only the caliper(s) or wheel cylinder(s) affected by that line must be bled. If the master cylinder required bleeding, then all calipers and wheel cylinders must be bled in the proper sequence:
      1. Right rear
      2. Left rear
      3. Right front
      4. Left front
    2. Bleed the individual calipers or wheel cylinders as follows:
      1. Place a suitable wrench over the bleeder screw and attach a clear plastic hose over the screw end. Be sure the hose is seated snugly on the screw or you may be squirted with brake fluid.
    Be very careful when bleeding wheel cylinders and brake calipers. The bleeder screws often rust in position and may easily break off if forced. Installing a new bleeder screw will often require removal of the component and may include overhaul or replacement of the wheel cylinder/caliper. To help prevent the possibility of breaking a bleeder screw, spray it with some penetrating oil before attempting to loosen it.
      1. Submerge the other end of the tube in a transparent container of clean brake fluid.
      2. Loosen the bleed screw, then have a friend apply the brake pedal slowly and hold. Tighten the bleed screw to 62 inch lbs. (7 Nm), release the brake pedal and wait 15 seconds. Repeat the sequence (including the 15 second pause) until all air is expelled from the caliper or cylinder.
      3. Tighten the bleeder screw to 62 inch lbs. (7 Nm) when finished.
    1. Check the pedal for a hard feeling with the engine not running. If the pedal is soft, repeat the bleeding procedure until a firm pedal is obtained.
    2. If the brake warning light is on, depress the brake pedal firmly. If there is no air in the system, the light will go out.
    3. After bleeding, make sure that a firm pedal is achieved before attempting to move the vehicle.

    Hope helps (remember to rate this answer).

    My 1997 chevy 1500 z71 brakes suddenly going all the way to the floor. Checked brake fluid and it was low. Could be wheel cylinder? Master cylinder? or ?


    well, check the brake lines for leakage after adding brake fluid to the full mark. If the brake pedal goes all the way to the floor, it's likely there is a leak somewhere after the master cylinder. If the pedal gets hard after adding fluid, and pumping it several times with the car off, then the master cylinder is still ok.

    If air has gotten into the master cylinder, it may have to be bled out on a bench, or using a scanner if that's the way your vehicle is.

    Bleeding the Brake System (ABS) Auto Bleed Procedure NOTE: Perform a manual bleeding procedure. If the brake pedal height and firmness results are not achieved, perform the auto bleed procedure below.
    NOTE: Perform this procedure when replacing the brake pressure modulator valve or electro-hydraulic control unit.
    1. Perform the manual brake bleeding procedure. Refer to Bleeding the Brake System (non-ABS).
    2. Check the master cylinder fluid level often to prevent running the system dry.
    3. Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure (for Gas engines) once, or the Function Test (for Diesel engines) four times. Make sure to release the brake pedal between each test.
    4. Perform the manual bleed procedure again. This should remove the remaining air from the brake system.
    5. Bleed the system as many times as needed to obtain the appropriate feel of the brake pedal.

    How do i bleed the brakes on a 1999 Pontiac Grand Am?


    Bleeding the Brake System
    When any part of the hydraulic system has been disconnected for repair or
    replacement, air may get into the lines and cause spongy pedal action (because
    air can be compressed and brake fluid cannot). To correct this condition, it is
    necessary to bleed the hydraulic system so to be sure all air is purged.

    When bleeding the brake system, bleed one brake cylinder at a time, beginning
    at the cylinder with the longest hydraulic line (farthest from the master
    cylinder) first. ALWAYS Keep the master cylinder reservoir filled with brake
    fluid during the bleeding operation. Never use brake fluid that has been drained
    from the hydraulic system, no matter how clean it is.

    The primary and secondary hydraulic brake systems are separate and are bled
    independently. During the bleeding operation, do not allow the reservoir to run
    dry. Keep the master cylinder reservoir filled with brake fluid.


    1. Clean all dirt from around the master cylinder fill cap, remove the cap and
      fill the master cylinder with brake fluid until the level is within 1/4 I n.
      (6mm) of the top edge of the reservoir.
    2. Clean the bleeder screws at all 4 wheels. The bleeder screws are located on
      the top of the brake calipers.
    3. Attach a length of rubber hose over the bleeder screw and place the other
      end of the hose in a glass jar, submerged in brake fluid.
    4. Starting at the right rear proceed in this order left front, left rear and
      right front.
    5. Open the bleeder screw 1/2 - 3/4 turn. Have an assistant slowly depress the
      brake pedal.
    6. Close the bleeder screw and tell your assistant to allow the brake pedal to
      return slowly. Continue this process to purge all air from the system.
    7. When bubbles cease to appear at the end of the bleeder hose, close the
      bleeder screw and remove the hose.
    8. Check the master cylinder fluid level and add fluid accordingly. Do this
      after bleeding each wheel.
    9. Fill the master cylinder reservoir to the proper level.

    Bleeding the Brake System
    Brake fluid tends to darken over time. This does not necessarily indicate contamination. Examine fluid closely for foreign matter.
    The primary and secondary hydraulic brake systems are separate and are bled independently. During the bleeding operation, do not allow the reservoir to run dry. Keep the master cylinder reservoir filled with brake fluid. Never use brake fluid that has been drained from the hydraulic system, no matter how clean it seems.
    1. Clean all dirt from around the master cylinder fill cap, remove the cap and fill the master cylinder with brake fluid until the level is within 1 / 4 in. (6mm) of the top edge of the reservoir.
    2. Clean the bleeder screws at all 4 wheels. The bleeder screws are located on the back of the brake backing plate (drum brakes) and on the top of the brake calipers (disc brakes).
    3. Bleeder screws should be protected with rubber caps. If they are missing, the orifice may easily become clogged with road dirt. If the screw refuses to bleed when loosened, remove it and blow clear. Aftermarket caps are readily available.

    Bleeding the ABS System
    This is accomplished using the same methods as for the base brake system. Refer to those procedures.
    ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system.
    1. Perform base brake bleeding. Refer to the appropriate section.
    2. Connect the scan tool to the data link connector beneath the dashboard.
    3. Select "Antilock Brakes" followed by "Miscellaneous", then "Bleed Brakes". Follow the instructions displayed until the unit displays "Test Complete", then disconnect the scan tool and proceed.
    4. Perform a base brake bleeding a second time.
    5. Top up the master cylinder.

    Hope helps (remember rated and comment this).

    Is there a special way to bleed the brake system on a 2001 catera


    1. Place a clean shop cloth beneath the brake master cylinder to prevent brake fluid spills.
    2. With the ignition OFF and the brakes cool, apply the brakes 3-5 times, or until the brake pedal effort increases significantly, in order to deplete the brake booster power reserve.

    Fill the brake master cylinder reservoir with DOT-3 brake fluid from a clean, sealed brake fluid container. Ensure that the brake master cylinder reservoir remains at least half-full during this bleeding procedure. Add fluid as needed to maintain the proper level. Clean the outside of the reservoir on and around the reservoir cap prior to removing the cap and diaphragm.
    1. Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve.
    2. Install a transparent hose over the end of the bleeder valve.
    3. Submerge the open end of the transparent hose into a transparent container partially filled DOT-3 brake fluid from a clean, sealed brake fluid container.
    4. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
    5. Loosen the bleeder valve to purge air from the wheel hydraulic circuit.
    6. Tighten the bleeder valve, then have the assistant slowly release the brake pedal.
    7. Wait 15 seconds, then repeat these steps until all air is purged from the same wheel hydraulic circuit.
    8. Repeat this procedure with the LEFT FRONT, then LEFT REAR and finally the RIGHT FRONT.
    9. Fill the brake master cylinder reservoir to the maximum-fill level with DOT-3 brake fluid from a clean, sealed brake fluid container.
    10. Slowly depress and release the brake pedal. Observe the feel of the brake pedal.

    How do i bleed my brakes for my 1998 Ford Ranger? When i push the brake pedal it goes all the way to the floor.


    First I would figure out why it needs to be bled, if it was leaking somewhere, or fluid low, new caliper, etc.

    Brake bleeding is the procedure performed on hydraulic brake systems whereby the brake lines (the pipes and hoses containing the brake fluid) are purged of any air bubbles. This is necessary because, while the brake fluid is an incompressible liquid, air bubbles are compressible gas and their presence in the brake system greatly reduces the hydraulic pressure that can be developed within the system.

    The process is performed by forcing clean, bubble-free brake fluid through the entire system from the master cylinder(s) to the calipers of disc brakes or the wheel cylinders of drum brakes). The brake bleeder is normally mounted at the highest point on each cylinder or caliper. Brake bleeding can be done easily by two persons working together and doesn't require much technical expertise besides a basic knowledge of brakes and car hydraulics. One wheel at a time, the brake bleeding valve for that wheel is opened while a drain hose is attached to that valve and immersed into a pool of brake fluid. The assistant then pumps the brake pedal. In this manner, fresh fluid is forced through the system into that wheel's caliper or wheel cylinder, and any old, dirty, water-saturated or bubble-entrained fluid is expelled from the system. When the fluid from the caliper or wheel cylinder runs clean, clear, and bubble-free, the brake bleeding valve is closed and the drain tube removed. The process is then repeated for the remaining wheels. During the entire process, the brake fluid reservoir must be kept full of fresh fluid lest new air bubbles be introduced into the brake system. (As found on Wikipedia)

    It would be important to note that the person pumping the brake should press slowly and tell you when they are nearing the end of the pedal stroke to you can close the bleed valve before you **** air back into the system. REMEMBER to keep brake fluid in the reservoir at the master cylindermag-glass_10x10.gif.

    Hope this helps. It's pretty easy and best done with 2 people, they hav vacuum bleeders which can be done with 1 person but the results are not consistant or perfect.
