I have an 01 GMC Jimmy 4.3L 4WD & we are trying to bleed the brakes but the scanner says my vehicle is going 3MPH so we manually bleed the brakes but the pedals still easily is pushed to the floor.


Bad master cylinder . What are you using a scan tool for ? No need Unless your Installing a new Electro-Hydraulic Control Unit (EHCU) or new Brake Pressure Modulator Valve (BPMV).
Hydraulic Brake System Bleeding (Manual)
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.
Place a clean shop cloth beneath the brake master cylinder to prevent brake fluid spills.
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.
If you have performed a brake master cylinder bench bleeding on this vehicle, or if you disconnected the brake pipes from the master cylinder, you must perform the following steps:
3.1. Ensure that the brake master cylinder reservoir is full to the maximum-fill level. If necessary add GM approved brake fluid from a clean, sealed brake fluid container. Refer to Fluid and Lubricant Recommendations.
If removal of the reservoir cap and diaphragm is necessary, clean the outside of the reservoir on and around the cap prior to removal.
3.2. With the rear brake pipe installed securely to the master cylinder, loosen and separate the front brake pipe from the front port of the brake master cylinder.
3.3. Allow a small amount of brake fluid to gravity bleed from the open port of the master cylinder.
3.4. Reconnect the brake pipe to the master cylinder port and tighten securely.
3.5. Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
3.6. Loosen the same brake pipe to purge air from the open port of the master cylinder.
3.7. Tighten the brake pipe, then have the assistant slowly release the brake pedal.
3.8. Wait 15 seconds, then repeat steps 3.3-3.7 until all air is purged from the same port of the master cylinder.
3.9. With the front brake pipe installed securely to the master cylinder, after all air has been purged from the front port of the master cylinder, loosen and separate the rear brake pipe from the master cylinder, then repeat steps 3.3-3.8.
3.10. After completing the final master cylinder port bleeding procedure, ensure that both of the brake pipe-to-master cylinder fittings are properly tightened.
Fill the brake master cylinder reservoir with GM approved 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.
Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve.
Submerge the open end of the transparent hose into a transparent container partially filled with GM approved brake fluid from a clean, sealed brake fluid container.
Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
Loosen the bleeder valve to purge air from the wheel hydraulic circuit.
Tighten the bleeder valve, then have the assistant slowly release the brake pedal.
Wait 15 seconds, then repeat steps 8-10 until all air is purged from the same wheel hydraulic circuit.
With the right rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right rear hydraulic circuit install a proper box-end wrench onto the LEFT REAR wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the left rear wheel hydraulic circuit bleeder valve tightened securely, after all air purged from the left rear hydraulic circuit, install a proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
With the right front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right front hydraulic circuit, install a proper box-end wrench onto the LEFT FRONT wheel hydraulic circuit bleeder valve.
Install a transparent hose over the end of the bleeder valve, then repeat steps 7-11.
After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly tightened.
Fill the brake master cylinder reservoir to the maximum-fill level with GM approved brake fluid from a clean, sealed brake fluid container.
Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
If the brake pedal feels spongy, repeat the bleeding procedure again. If the brake pedal still feels spongy after repeating the bleeding procedure, perform the following steps:
21.1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection.
21.2. Pressure bleed the hydraulic brake system in order to purge any air that may still be trapped in the system.
Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
Important: If the brake system warning lamp remains illuminated, DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
If the brake system warning lamp remains illuminated, refer to Symptoms - Hydraulic Brakes

Slow bleeding of my 3 series bmw car in brake caliper in rear..


are you replacing pads? rear brakes have less work to do theres probably some kind of bias valve sorting out which wheel needs most pressure,any thing else like a sticky caliper or damage to any of the pipes

WhaT is the cause of slow bleeding in brake caliper?


The front calipers are closer to the master cylinder so you are bleeding a short brake line.
The rear calipers are farther away so the lines are longer and it requires more brake fluid to flush the air out of them.

I have a 2002 bmw 325i E46. I do not have a full brake pedal unless I pump the brakes a couple times. If I slam on brakes hard, the brake light comes on the dash. The brakes have been professionall


pumping the brakes is an indication of out of adjustment brakes. However if you have disc brakes all around then that will not be the case. IF you have drum brakes on the rear then the brakes have not been properly adjusted . Pressure bleeding does not necessarily mean that there is no air in the system. I suggest that there is still air in the system in one of the circuits from the master cylinder or the master cylinder has not been primed before fitting
May be you should have the problem investigated by an accredited brake shop before something drastic happens.

Bleeding brakes


bleeding the brakes -
look fo the bleeder ( zerk fitting ) on the side of the caliper, attach a 1/4 inch clear hose to this fitting and run hose into a catch pan or bottle,, make sure you have plenty of brake fluid in the reservoir ( re-fill as needed during the bleeding process ), have a helper sit in the car and ready to press down the brake pedal, with brake pedal up - open the zerk fitting using a small wrench, have the helper press down and hold the brake pedal to the floor, with the pedal down - close the zerk fitting, your helper can now release the pedal, ( repeat this about 3 to 4 times or until clean and bubble free fluid flows through the clear hose ) --- top off the reservoir with fluid and repeat these steps for the other brake calipers. Note: if brake pedal feels sloppy ( not firm ) then there is still air in one of the lines,, continue bleeding until pedal feels like it has some resistance.

Brake fluid is not coming out when i open the bleeder at the rear wheel on 89 ford tempo


Good day Robert W73, there should be a metal pipe leading from the master cyclinder to the rear wheels and to the front wheels. Try loosening the pipe on the master cylinder and pump the brakes. It might be that there is an air lock in the master cylinder. By loosening this pipe the air forsing the brake fluid back will be released. As soon as the clean brake fluid comes out of the pipe tighten the pipe again and pump the brakes. Then step on the brake pedal and hold it in, while the brake pedal is depressed open the bleeding nipple and close it again. Repeat this procedure till you have clean brake fluid comming out of the bleeding nipple. Just remember to bleed all the wheels starting at the wheel furthest from the master cylinder and working your way to the closest wheel.

I hope this helps. If it does not help you might need to replace the seals on the inside of the master cylinder or you will have to replace the master cylinder itself as there might be pit marks on the inside causing the hydraulic fluid to bypass the seals.

Driver side brake not bleeding properly after bleeding left side and changing rotors, calipers, and pads?


first of all make sure master cylinder is full of brake fluid.then you crank car leave foot off brake pedal. watch abs light on dash it should turn off in 10 seconds if not have car towed to garage or dealer. they have to use a scanner to scan the abs brakes if abs light turn off in 3 seconds. then starting bleeding from master bleed the lower brake line fitting at the proportional valve followed by the upper brake line fitting. keep eye on brake fluid in mastercylinder dont let run dry.next prime the abs hydralic modulator.connect the bleeder hose to the rear bleeder valve on the modulator.place the other end into a container partially filled with cleab brake fluid.make sure the end of the hose is submerged.open the bleeder valve slowly about 1/2 to 3/4 turn have an assistant depress the brake pedal and hold it in the depressed position. when the flow of fluid ceases close the bleeder valve.repeat process until no air bubbles are present in the fluid.then tighten the bleed valve securely. start bleeding brakes. your bleeding sequence is right rear - left front - left rear - right front.WARNING IF ALL FAILS YOUR BRAKES DONT FEEL SOLID AND FEEL VERY SPONGY.DONT DRIVE CAR. HAVE IT TOWED TO DEALERSHIP.THEY WILL HAVE TO PRESSURE BLEED YOUR BRAKE SYSTEM.

N REG POLO changed pads replaced rear wheel cylinder for brake shoes then bled brakes then turn engine on moved car 10ft pressed brake pedal it was like a sponge


You must still have air in one of the pipes - not necessaryily only to the wheel you have been working on (though normally that is so). Did youu make sure that the fluid level remained above minimum in the brake fluid master cylinder while you were bleeding the brakes? Possibly a slurp of air went in there and now the other pipes will need bleeding too. Don't panic - just bleed all the brake pipes, making sure that the master cylinder level stays high.
