master cylinder problems Sign In

I put new brake pads and shoes on my 1988 Chevy Silverado K1500 and adjusted the rear brakes. When I was done I stepped on the pedal to center the shoes, as I have always done with all my other vehicles when I did a brake job. After one or two pumps the pedal went to the floor and I was unable to get a good pedal. I figured the master cylinder failed so I bought a remanufactured one and installed it. I still have the same problem in that the pedal goes to the floor and won't pump up to a good pedal in order to bleed the brakes.

Some thoughts on this:

Are you convinced that bench bleeding the master was ok?

If you are using a helper to pump the brake for bleeding are they holding the pedal down till you tighten up the bleeder? If not it'll just suck air back in.

Also: It's possible you have a bad new master cylinder and that's tough to determine, T

Check the proportioning valve. Sometimes the check valve on the front needs to be reset (by pushing back in). It has a little black rubber boot around it.

I would suspect damaged brake line ( rubber flex line LF and RF )
