You must bleed the system and keep toping up the brake fluid in the tank

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

Brakes go to floor i changed master,4 calipers,4 brake hoses, and all pads


Time to redo the bleeding of the system again...starting with the master cylinder...you do not have to remove the master to re-bleed it. disconnect both brake lines from the master, and start again by pushing pedal to floor, and rebleed each line at the master...this is critical to work properly...you mentioned new master cylinder, if remanufactured I would return it. As noted above, after confirming the master is fully bled...rebleed each caliper beginning with the rear, farthest away from the master...you must have "air" in the brake lines. Hope this helps.

Brake pedal goes all the way to the floor, will slow the car a little, but wont fully brake. master cylinder is fine, calipers and pads are new, brake lines look okay, it's holding brake fluid fine, lines...


must be something you have overlooked. clamp off the front brake hoses and rear hose. if you dont have the propper clamps use g clamps or locking pliars. try the pedal then. if it still goes to the floor its either air in the lines or the master cylinder is no good..Bleed the master cylinder at the lines first,then work back.

Brakes sink to the floor


by stating that your pedal sinks to the floor, you leave 3 options open 1.) the master cylinder seal is bypassing allowing the fluid to bleed by the proper correction is to rebuild the master cylinder.
2. One of your drum brakes has a wheel cylinder that has failed causing a noticable behind the tire leak (most common) correction is to replace all brake hardware and wheel cylinder.
3. One of the brake lines is cracked,broken, inspect for leaks and replace with new line.
4. notice on disc brakes if a brake caliper fails (part that squeezes brake pads to rotor) you will have the same symptoms of a broken wheel cylinder, this would of gradually occured feeling a heavy pedal or pulsation.

Just replaced rotors, calipers, caliper brackets, and pads. Bled all four wheels, starting with the farthest away from the master cylinder working my way to the closest. Brake pedal feels firm when car...


Bleed with the car running and make sure all the air is out. Now make sure there is no leak and the pad contact are adjusted without much gap so that the calipers hold on. make sure the servo assist is correct, if so and the master cylinder was set right , it must work. Please recheck all your work once again to trim up.

I have a slow brake fluid loss. I think it may from the master cylinder. Are there any seals in the lines that go into the master cylinder unit.


no they are inverted flare fittings no seals check all lines and calipers/wheel cylinders if all are dry remove the vacuum hose from the booster if there is brake fluid in the hose the master cylinder is bad

Pistons in both front calipers stay out, both calipers replaced


You may have a leak in the booster or master cylinder. You can put a pressure tester on the system to test for leaks. It does sound like you have an air leak.
You can try to bleed the master cylinder, then slave cylinder, then brake lines.

Brakes to the floor(almost) 99 blazer


bleed the brake again. if the pedal goes to the floor with little resistance, then the master cylinder is your problem.
the shim is to depress the noise when you applied the brake. you can skip that, if the brake works without it.
