Do you have a/the proportioning valve in your system? Pin needs to be pulled out for centering while bleeding.

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 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.

Bleeding abs 1993 chevrolet p/u, brakes are not solid, I have bled all cylinders starting with master cylinder, left rear to front disc.The pedal is soft and brake light stays on? I have replaced new brake...

Did you bench bleed the MC before installing it? If not, that's the problem. MUST be bench bled or you'll always have air. If brakes lights are on, the brake switch is out of adjustment OR (since you replaced the MC), the push rod is out of adjustment

I have re/re the rear brake cylinders,shoes,drums,front rotors,pads,and callipers on my 2000 gmc safari van.i have bled all the brakes. but the drivers front has no pressure or fluid.the other three brakes...

make sure you are bleeding them by doing them as an abs system,do the right rear then the left front,then the left rear then the right front,the opposite wheels are how the system brakes.

Rear brakes won't work

This is just a shot on the dark but did you use a low end brake fluid as this has been known to cause braking problems.
