Manual

WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately.

CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.

CAUTION: Brake fluid is harmful to painted and plastic surface's. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.

NOTE: When any part of the hydraulic system has been disconnected for repair or installation of new components, air can get into the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or with pressure bleeding equipment.

  1. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with the specified brake fluid.

  2. Place a box end wrench on the RH rear bleeder screw. Attach a rubber drain tube to the RH rear bleeder screw and submerge the free end of the tube in a container partially filled with clean brake fluid.
  3. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
  4. Loosen the RH rear bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the RH rear bleeder screw.
    • Repeat until clear, bubble-free fluid comes out.
    • Refill the brake master cylinder reservoir as necessary.
  1. Tighten the RH rear bleeder screw.
  2. Repeat Steps 2, 3, 4 and 5 for the LH rear bleeder screw.
  3. Place a box end wrench on the RH front disc brake caliper bleeder screw. Attach a rubber drain tube to the RH front disc brake caliper bleeder screw, and submerge the free end of the tube in a container partially filled with clean brake fluid.
  4. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
  5. Loosen the RH front disc brake caliper bleeder screw until a stream of brake fluid comes out.
    • While the assistant maintains pressure on the brake pedal, tighten the RH front disc brake caliper bleeder screw.
    • Repeat until clear, bubble-free fluid comes out.
    • Refill the brake master cylinder reservoir as necessary.
  1. Tighten the RH front disc brake caliper bleeder screw.
  2. Repeat Steps 7, 8, 9 and 10 for the LH front disc brake caliper bleeder screw.

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

Why were the brake lines replaced?

Sounds like the mastercylinder may have run dry. You have to bench bleed the master and then DO NOT allow fluid to run low, while bleeding brakes...

if master cylinder runs low on fluid and air gets in, almost impossible to bleed with out releasing the lines and bleed master it self.

How to bleed the brakes on my 2002 Buick rendezvous cxl


If the standard bleeding procedures do not produce an acceptable pedal you will need a scantool that can activate the automated ABS bleed and a pressure bleeding system.
To bleed the brakes use the standard pattern of RR,LR,RF,LF

ABS Automated Bleed Procedure
Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in Service Precautions.
Important: In most circumstances a base brake bleed is all that is required for most component replacements (such as wheel cylinders, calipers, brake tubes, and master cylinder) except for brake pressure modulator valve (BPMV) replacement.
The following automated ABS bleed procedure is required when one of the following occur:
Manual bleeding at the wheel cylinders does not achieve the desired pedal height or feel.
BPMV replacement
Extreme loss of brake fluid has occurred.
Air ingestion is suspected.
If none of the above conditions apply, use standard bleed procedures.
The auto bleed procedure is used on BOSH 5.3 equipped vehicles. This procedure uses a scan tool to cycle the system solenoid valves and run the pump in order to purge the air from the secondary circuits. These secondary circuits are normally closed off, and are only opened during system initialization at vehicle start up and during ABS operation. The automated bleed procedure opens these secondary circuits and allows any air trapped inside the BPMV to flow out toward the wheel cylinders or calipers where it can be purged out of the system.
Automated Bleed Procedure
Preliminary Inspection
Inspect the battery for full charge, repair the battery and charging system, as necessary.
Connect a scan tool to the data link connector (DLC) and select current and history DTCs. Repair any DTCs prior to performing the ABS bleed procedure.
Inspect for visual damage and leaks and repair, as needed.
Preliminary Setup
Raise and vehicle on a suitable support.
Turn the ignition switch to the OFF position.
Remove all 4 tires, if necessary.
Connect the pressure bleeding tool according to the manufacturer's instructions.
Turn the ignition switch to RUN position, engine off.
Connect a scan tool and establish communications with the ABS system.
Pressurize the bleeding tool to 206 - 241 kPa (30 - 35 psi) .
Performing the Automated Bleed Procedure
Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturers instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces.
With the pressure bleeding tool at 206 - 241 kPa (30 - 35 psi) , and all bleeder screws in closed position, select Automated Bleed Procedure on the scan tool and follow the instructions.
The first part of the automated bleed procedure will cycle the pump and front release valves for one minute. After the cycling has stopped the scan tool will enter a cool down mode and display a 3 minute timer. The auto bleed will not continue until this timer expired, and cannot be overridden.
During the next step, the scan tool will request the technician to open one of the bleeder screws. The scan tool will then cycle the respective release valve and pump motor for one minute.
The scan tool will repeat step 3 for the remaining bleeder screws.
With the bleeder tool still attached to the vehicle and maintaining 241 kPa (35 psi) , the scan tool will instruct the technician to independently open each bleeder screw for approximately 20 seconds. This should allow any remaining air to be purged from the brake lines.
When the automated bleed procedure is completed the scan tool will display the appropriate message.
Install all 4 tires, if necessary refer to Tire and Wheel Removal and Installation.
Remove pressure from the pressure bleeding tool and then disconnect the tool from the vehicle.
Depress the brake pedal to gage pedal height and feel. Repeat steps 1-8 until the pedal is acceptable.
Remove the scan tool from the DLC connector.
Install.
Lower the vehicle.
Inspect the brake fluid level in master cylinder.
Road test the vehicle while making sure the brake pedal remains high and firm.
If the vehicle is equipped with a traction control system (TCS), the scan tool will cycle both the ABS and the TCS solenoid valves. This bleed procedure is the same as above.

Vic, Because you changed master cylinder air probably got into the ABS modulator. Air can be very difficult to remove from an ABS modulator assembly because of the solenoid valves, if no bleed screw on the modulator, you may need a pressure bleeder and a scan tool to cycle modulator to bleed trapped air. Check the attached links,instruction and guides, Good luck. "I hope this helped you out, if so let me know by pressing the helpful button.

ABS light and traction light and no cruise control


how on earth would the blind know what is wrong.?
scan it? yet?
btw, newer cars cut cruise feature for any signs of danger.
new laws...
the traction needs ABS to work ,so forget that and fix ABS.
ABS needs 2 things to work , brakes and ABS.

so if brakes are bad, then ABS will get upset.
after all, if it cant brake right, how can the puter save you?
if brakes are known to be ok (inspections work here)
but in this case it was BREACHED by you, with out reading the book first.
then scan the ABS. (omg? code for dead sensor?) nah, you caused it..
easy

ABS resets every key on. so...
my guess, if ABS was happy before your actions( you never said)
then you got air in to the system. and failed to follow the FSM instructions on bleeding brakes, in ABS car.

front caliper, did you block the hose with cap, so it didn't allow air to the modulator? oops... never just let them drip... or . max pain.
bleed it again, (using any or all 5 ways to do so, bleeding is skill thing) (many modulators can not just be simply bled)

now Ill quote the 2012 fSM for you , under brakes

Data: -----------------------------------------------------------------
ABS Brake Bleeding
STANDARD PROCEDURE - ABS BRAKE BLEEDING

ABS system bleeding requires conventional bleeding methods plus use of a 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.

Perform base brake bleeding, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Connect scan tool to the Data Link Connector.

Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then ABS BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed.

Perform base brake bleeding a second time, (Refer to Brakes - Standard Procedure)(Refer To List 1).

Top off master cylinder fluid level and verify proper brake operation before moving vehicle.

My slave cylinder on my 2000 Isuzu Rodeo went out and I need information on the procedure required to replace it ?


what you need to do is buy a replacement (new) cost is relvantly cheap. the correct brake fluid in aust it is known as dot 3 don\'t use any other even the multi dot 3/ 4 is no good for rubber seals. place a line lock on rubber part of hose so you don\'t loose the fluid from master cylinder . remove old unit by undoing the banjo bolt which carries the fluid first then the location bolts. replace new unit in reverse order bolted on then the fluid bango bolt with the washers to seal the fluid . after fully bolted back in undo the bleed nipple on the slave cyl then remove the line lock, keep the resvoir full with new clutch fluid . let the old fluid gravety feed out of complete unit , remembering to keep res full once new fluid is coming thru , tighten the bleed screw and get some one to help you bleed the unit properly . very easy job to do and quite common as the brake fluid is hydrascopic meaning it absorbs water , the water goes to the lowest point being the slave cyl. it is recommended that brake fluid and clutch fluid be replaced yearly due to the hydrascopic nature of it and it is the water that damages the seals and surfaces which then fail just as yours has . hope this helps mate

It's pretty much the exact same process just remove your abs relays/fuses
if the brake bleeding doesn't work it sounds like you may need a new master cylinder

Soft brakes


You have a leak in the brake system, need to check the medal brake lines that run through the frame rail and goes to the back wheels, It is common for those to rust into towards the back. If lines are okay then check the wheel cylinders. If you are not low on brake fluid then you probley have a bad master cylinder.

When driving my 2000 pontiac sunfire, I will use my brakes and sometimes they go to the floor and the car barely comes to a stop. Sometimes they work fine though. If I pump the brakes they work fine as...


try this ABS bleeding procedure:

WITHOUT TECH 1® OR T-100®

Do not place your foot on the brake pedal through this entire procedure unless specifically instructed to do so.
This method can only be used if the ABS warning lamp is not illuminated and not DTC's are present.
  1. Remove your foot from the brake pedal.
  2. Start the engine and allow it to run for at least 10 seconds while observing the ABS warning lamp.
  3. If the ABS warning lamp turned ON and stayed ON after about 10 seconds, the bleeding procedure must be stopped and a Tech 1® must be used to diagnose the ABS function.
  4. If the ABS warning lamp turned ON for about 3 seconds, then turned OFF and stayed OFF, turn the ignition OFF .
  5. Repeat Steps 1-4 one more time.
  6. The entire brake system should now be bled by following the guide or pressure bleeding procedure.

Manual Bleeding
See Figure 3
  1. Clean the master cylinder fluid reservoir cover and surrounding area, then remove the cover.
  2. Add fluid, if necessary to obtain a proper fluid level, then put the reservoir cover back on.
  3. Prime the ABS hydraulic modulator/master cylinder assembly as follows:
    1. Attach a bleeder hose to the rearward bleeder valve, then submerge the opposite hose end in a clean container partially filled with clean brake fluid.
    2. Slowly open the rearward bleeder valve.
    3. Depress and hold the brake pedal until the fluid begins to flow.
    4. Close the valve, then release the brake pedal.
    5. Repeat Steps 3b-3d until no air bubbles are present.
    6. Relocate the bleeder hose to the forward hydraulic modulator bleeder valve, then repeat Steps 3a-3e.

  4. Once the fluid is seen to flow from both modulator bleeder valves, the ABS modulator/master cylinder assembly is sufficiently full of fluid. However, it may not be completely purged of air. At this point, move to the wheel brakes and bleed them. This ensures that the lowest points in the system are completely free of air and then the assembly can purged of any remaining air.

Fig. Fig. 3: ABS hydraulic modulator/master cylinder bleeder locations

  1. Remove the fluid reservoir cover. Fill to the correct level, if necessary, then fasten the cover.
  2. Raise and safely support the vehicle.
  3. Proceed, as outlined in the following steps, to bleed the wheel brakes in the following sequence: right rear, left rear, right front, then left front.
    1. Attach a clear plastic bleeder hose to the bleeder valve at the wheel, then submerge the opposite hose end in a clean container partially filled with clean brake fluid.
    2. Open the bleeder valve.
    3. Have an assistant slowly depress the brake pedal.
    4. Close the valve and slowly release the release the brake pedal.
    5. Wait 5 seconds.
    6. Repeat Steps 7a-7e until the brake pedal feels firm at half travel and no air bubbles are observed in the bleeder hose. To assist in freeing the entrapped air, tap lightly on the caliper or braking plate to dislodge any trapped air bubbles.

  4. Repeat Step 7 for the remaining brakes in the sequence given earlier.
  5. Carefully lower the vehicle.
  6. Remove the reservoir cover, then fill to the correct level with brake fluid and replace the cap.
  7. Bleed the ABS hydraulic modulator/master cylinder assembly as follows:
    1. Attach a clear plastic bleeder hose to the rearward bleeder valve on the modulator, then submerge the opposite hose end in a clean container partially filled with clean brake fluid.
    2. Have an assistant depress the brake pedal with moderate force.
    3. Slowly open the rearward bleeder valve and allow the fluid to flow.
    4. Close the valve, then release the brake pedal.
    5. Wait 5 seconds.
    6. Repeat Steps 11a-11e until no air bubbles are present.
    7. Relocate the bleeder hose to the forward hydraulic modulator bleeder valve, then repeat Steps 11a-11f.

  8. Carefully lower the vehicle, then check the brake fluid and add if necessary. Don't forget to put the reservoir cap back on.
  9. With the ignition turned to the RUN position, apply the brake pedal with moderate force and hold it. Note the pedal travel and feel. If the pedal feels firm and constant and the pedal travel is not excessive, start the engine. With the engine running, recheck the pedal travel. If it's still firm and constant and pedal travel is not excessive, road test the vehicle and make sure the brakes are operating properly.
  10. If the pedal feels soft or has excessive travel either initially or after the engine is started, the following procedure may be used:
    1. With the Tech 1® scan tool, Release then Apply each motor 2-3 times and cycle each solenoid 5-10 times. When finished, be sure to Apply the front and rear motors to ensure the pistons are in the upmost position. DO NOT DRIVE THE VEHICLE.
    2. If a Tech 1® scan tool is not available, remove your foot from the brake pedal, start the engine and allow it run for at least 10 seconds to initialize the ABS. DO NOT DRIVE THE VEHICLE. After 10 seconds, turn the ignition OFF . The initialization procedure most be repeated 5 times to ensure any trapped air has been dislodged.
    3. Repeat the bleeding procedure, starting with Step 1.

  11. Road test the vehicle, and make sure the brakes are operating properly.

1994 Cavalier -replaced master cylinder-no pressure to rear brake


The most common bleeding procedure is to bleed the ABS brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.
Air can be very difficult to remove from an ABS modulator assembly because of all the nooks and crannies inside the unit. The modulator may have eight to 10, or more, ABS/traction control solenoid valves, plus various check valves and dead-end ports. Some ABS modulators have special bleed screws to help you vent the trapped air when bleeding the system. Others do not and require the use of a scan tool to cycle the ABS solenoids while you bleed the system. 1. To bleed the isolation valves in the modulator, there are two bleeder screws. Start with the one toward the engine. Turn the ignition on and apply light pressure on the brake pedal. Open the bleeder screw and allow the fluid to flow until clear. Close the screw and do the same at the second bleeder screw. 2. Depressurize the accumulator by pumping the pedal 40 times with the key off. Wait about two minutes for the brake fluid to de-aerate, then refill the fluid reservoir with DOT 3 brake fluid. 3. Now you can bleed the boost section. This is done by applying moderate pressure on the brake pedal and turning the ignition on for three seconds, then off. Repeat this a total of 10 times. Make sure the pedal feels firm when you have finished, and give the car a road test to make sure the brakes are working properly.
