do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.

You still have air in the system. You will have to bleed more. I had to bleed a quart of brake fluid out of each wheel to get good brakes on my 1996 GMC.

Have a 99 Toyota camry n brake light is on after changing right front brake caliper


Master cylinder fluid piston has entered into a brake safe mode.
when the high pressure brake system is opened in any way, the brake master cylinder piston reaches to the far end of the master cylinder which trips the brake system warning light.

This brake light condition is due to sudden loss of brake fluid pressure on the right front brake caliper assembly during the replacement.

Left rear brake caliper bleed valve will ned to be "opened" until master cylinder piston travels into the opposite direction which "resets" the brake system warning light.

Dot 4 brake fluid recommened for most, but not all vehicles.
Reference vehicle to owners manual for replacement fluid is replaced under master cylinder brake system cap.

With motor shut off, I have good break pressure, but when the motor is started, the pedal goes to the floor.


Was the entire not bleed at all?

Master cylinders do not fail as fast as
the people on this site change them

They are replaced but never because they fail
people don't know how to diagnose brake issues

When the car is off you are pressing against the power
booster vacuum not the brake fluid

How can i tell if master cylinder on my 91 buick park ave is done the break pedal goa all the way down as soon as i turn car on. o not see any fluid leaks. car stops if you pump breaks but slowly?


Most likely you need brake job on front and rear. to test if the pads are worn on the rear set the emergency brake then push down on the brake. does it come up? if it does This means the rear pads are bad and most likely the front. You will want to check the master cylinder for fluid if it is low you will have to replace with DOT3 Fluid once it is full you may have to bleed the system to see if the brakes come up. If the fluid is ok and The pads are not wore out then you will have to check the master cylinder to do this you need to jack up the car one wheel at a time and test by pressing brake pedal down slowly till the wheel will not turn. If the wheels stop on all four wheels when you have done this test then you will need to replace the pads and shoes. If the master cylinder is defective either the front wheels won't stop or the rear won't stop turning when you press the pedal down. The Master cylinder is $39.00 with exchange, but you want to make sure the pads are good the rear shoes are good and the brakes are adjusted. Here is the web page for the parts you need. If you need help doing a brake job let me know and I will give you whatever information you would need to do the job with. You can test the master cylinder if you have rubber gloves too, just pop the lid off the master cylinder and have someone slowly push the pedal down with your finger on the front port see it you get fluid blowing out the hole when the pedal is pushed down. If you do the cup is bypassing and it needs to be replaced. Hope this helps.

2004 buick park ave. rt front brake drags, gets hot! caliper replaced, twice! brake hoses replaced, new master cylinder cap and gasket, bled all fluid from system, and replaced with new. seems to drag on...


THE ANTILOCK BRAKE SYSTEM COULD BE THE CULPRIT HERE. YOU WILL NEED TO TAKE IT TO YOUR LOCAL REPAIR SHOP OR DEALER AND HAVE THEM DO A PRESSURE BLEED ON THE BRAKE SYSTEM. THEY SHOULD ALSO PERFORM AN ABS SYSTEM BLEED WHICH IS DONE WITH THE SCAN TOOL. THIS SHOULD TAKE CARE OF THIS PROBLEM. HOPE THIS HELPS!!

Replacement fo rear brake pads on a 2005 buick park ave, how do you depress the cyl to slide over the new pads


Use a large C-clamp and a thin piece of wood...compress slowly so you don't over-pressurize the master cylinder.

Hi there!

Check for leaks at the slave cylinders and flexi hoses.

After several attempts of losing pressure - check the brake fluid level in the master.

If you arn't losing any fluid, You've got a damaged seal in the Master cylinder, or are drawing air in due to improper adjustment (excess travel) of slave cylinders.

Are you trying this with engine running? - How does this affect it (using servo assist)
