Simple way - takes 2 people. Get a small jar, and fill it part way with some brake fluid. Then use a short length of hose (one that fits snugly over the bleed screw), and keep one end in the brake fluid. With the engine off, loosen the bleed screw, and have the brake pedal slowly depressed. Close the bleed screw BEFORE releasing the brake pedal, and repeat until no air bubbles come out the hose. Top up the brake reserve with fluid.

SOURCE: Bleed cooling system

Assuming you have already filled your cooling system with the proper G12 coolant to the cross-hatch level, open the coolant overflow/fill bottle cap. Leave it off. Start the car and let it idle. Turn your heater on full hot and full fan speed. Let it come up to temp so the thermostat opens up and allows coolant to flow through your system. When the system burps, you'll see air bubbles show up in the overflow tank. Let it cycle a another time and then top off the coolant if needed. Then close up the cap and call it a day.

get a one man bleeder kit from halfords (about £7) and then you can go around the car and bleed the brakes without a assistant, you just attach the tool to the nipple on the caliper, loosen the nut, press the brake pedel a few times till there is no more bubbles in the hose and then move on to the next corner, there is a specific way to go around the car but if you start at the back and finish at the front it should be ok

Please don't forget to rate:


Bleeding The Brake System Bleeding When any part of the hydraulic system has been disconnected for repair or replacement, air enters the lines causing spongy pedal action (because air can be compressed and brake fluid cannot). To correct this condition, it is necessary to bleed the hydraulic system to ensure all air is purged.
Always begin bleeding the brake system from the furthest wheel cylinder or caliper from the master cylinder; the right rear.
NOTE: The right side of the vehicle is the passenger side. The sides of the vehicle are determined from the driver's perspective. This reference is taken from sitting in the driver's seat, facing forward.
Maintain a full reservoir during the bleeding operation. Never use brake fluid that has been drained from the hydraulic system, or from an open container, no matter how clean it is. Always use brake fluid from a new, sealed container. The front and rear reservoir will drain as the front or rear brakes are bled.

  1. Park the vehicle on a level surface. Place the vehicle in PARK (automatic) or REVERSE (manual) with the engine OFF, and apply the parking brake. Chock the rear wheels to prevent vehicle movement. NOTE: Wheel chocks may be purchased at your local auto parts store, or a block of wood cut into wedges may be used.
  2. Loosen the lugnuts from all four wheels, but do not remove the lugnuts until the vehicle is raised and supported properly.
  3. Use an approved jack and raise the vehicle high enough to place jack stands under all four corners of the vehicle. Place the jack stands under the frame or axles of the vehicle. Ensure that the front of the vehicle is raised higher than the rear.
  4. Remove the wheels from the vehicle.
  5. 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.
  6. Clean the bleeder screws at all four wheels. The bleeder screws are located on the back of the brake backing plate (drum brakes) and at the top of the brake calipers (disc brakes).
  7. Attach a length of rubber hose over the bleeder screw and place the other end of the hose in a plastic jar.
  8. Have an assistant place and hold pressure on the brake pedal.
  9. Open the bleeder screw 1/2 - 3/4 turn. As the bleeder is opened, the brake pedal will travel to the floor. Have the assistant inform you when the pedal has bottomed out. NOTE: Do not remove pressure from the brake pedal once it is bottomed out. No movement to the pedal should occur until the bleeder is closed and the assistant is made aware of the situation. Failure to do this will draw more air into the system.
  10. Close the bleeder screw and tell your assistant remove their foot from the brake pedal. Continue this process to purge all air from the system.
  11. When bubbles cease to appear at the end of the bleeder hose, tighten the bleeder screw and remove the hose.
  12. After bleeding each wheel, check the master cylinder fluid level and add fluid accordingly.
  13. Repeat the bleeding operation at the remaining three wheels, ending with the one closet to the master cylinder. The pattern is, RR, LR, RF, LF.
  14. Fill the master cylinder reservoir to the proper level and install the reservoir cap.

SOURCE: brake bleeding

if you didn't bleed the lines after putting the master in. then there is a good chance there is air in the lines now. may go through a quart of brake fluid before all the air is out. remember to start at r-rear/ l-rear/ r-front/ l-front last.will take some time. don't forget to adjust the rear brake while your there to help with the pedal

I have a ford escort xr3i 1988 i have replaced the brake master cylinder, bleed the brakes but still have no brakes what could be wrong?


Your car has a diagonally split brake system. Each side of this system must be bled as an individual system, and there is a correct bleeding sequence to be followed. First bleed the right rear brake, second, bleed the left front brake, then follow with the left rear brake and lastly, bleed the right front brake.Here's a link on a repair guide for bleeding your brakes.

Bleed brakes and will not hold aftet bleeding


You have to bleed the whole system in sequence. It is a two man job. you have air in the system. You must bleed each wheel starting with the wheel farthest from the master cylinder. then the next wheel that shares the same circuit then the next and the next. Each car has its own sequence to follow. front wheel drive cars bleed differently than rear wheel cars . You must keep the master cylinder full as you do this, as to not allow any more air to enter the system. If air has entered the ABS system it will have to be bleed as well .. You have to refer to a manual for your car.

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.

    How do you bleed the brake system on 2003 suzki grand yitara 4x4 with abs brakes


    The hydraulic brake system must be bled any time one of the brake lines is disconnected or air enters the system. There are two ways to bleed the system; pressure bleeding or manual bleeding. Both procedures will be given here, although pressure bleeding requires the use of some fairly expensive equipment (a pressure tank) and is seldom used. Both methods are equally effective.The correct bleeding sequence is: left front, right front, left rear, and right rear. On master cylinders equipped with a bleeder valve, bleed the master cylinder last.
    PRESSURE BLEEDING
    1. Clean the top of the master cylinder, remove the cover, and attach the pressure bleeding adapter.
    2. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
    3. Check the pressure bleeder reservoir for correct pressure 20-29 psi (137-206 kPa) and fluid level, then open the release valve.
    4. Fasten a bleeder hose to the wheel cylinder or caliper bleeder nipple and submerge the free end of the hose in a transparent receptacle. The receptacle should contain enough brake fluid to cover the open end of the hose.
    5. Open the wheel cylinder or caliper bleeder nipple and allow the fluid to flow until all bubbles disappear and an uncontaminated flow exists.
    6. Close the nipple, remove the bleeder hose and repeat the procedure on the other wheel cylinders according to the sequence.


    MANUAL BLEEDING(see Figures 1, 2 and 3)An alternative to the pressure method of bleeding requires two people to perform; one to depress the brake pedal and the other to open the bleeder nipples.
    1. Clean the top of the master cylinder, and then remove the cover and fill the reservoir with clean brake fluid.
    2. To prevent squirting fluid replace the cover.
    3. The spring-loaded plunger on the front of the proportioning valve must be depressed while bleeding. Wire or tape can be wrapped around the valve to hold the plunger in.
    4. Install a box end wrench on the left front bleeder screw.
    5. Attach a length of small diameter, clear vinyl tubing to the bleeder screw. Submerge the other end of the rubber tubing in a glass jar partially filled with clean brake fluid. Make sure the rubber tube fits on the bleeder screw snugly or you may be squirted with brake fluid when the bleeder screw is opened.
    6. Have your friend slowly depress the brake pedal. As this is done, open the bleeder screw half a turn and allow the fluid to run through the tube. Close the bleeder screw, then return the brake pedal to its fully released position.
    7. Repeat this procedure until no bubbles appear in the jar. Refill the master cylinder.
    8. Frequently check the master cylinder level during this procedure. If the reservoir runs dry, air will enter the system and the bleeding will have to be repeated.

    Hope helps.

    How do I bleed my brake lines on a 1999 Oldsmobile Bravada


    This job is a lot easier with two people but you can do it with 1 if you have to. Have someone sit inside and pump the brakes 3 or 4 times and on the 4th pump hold it to the floor(all the way to the floor and don't let up at all). While they hold it to the floor you take a little end wrench and (Starting on driver side front going to pass. front next then pass. back and so on) you should already have the tire off before pumping brakes. On the caliper(the thing that holds the pads) there is a little bleeder nut Should be near where your brake line goes into the caliper. Now while they hold the pedal down you loosen that nut just a little bit and it should spit a little bit then maybe some fluid will come out maybe not on the first time but it does happen. Just dont leave it open longer than a couple seconds. Just long enough for air to escape then tighten back down. Repeat all those steps about 4 or 5 times for each tire or until brake pedal feels hard to push in. Make sure while your bleeding that you check your master cylinder often if you let it run out u will have to start over from the beginning. Also make sure who ever is holding the pedal do not let up when bleeder valve is open. Same thing. I just wantedn to m
