65 C-10 brake disc brakes

[older/wiser?]

We have a 65 C-10 with CPP disc kit with 6 lug rotors and 3" lower springs and shocks, Corvette 8" booster and master. It still has stock rear brakes, all new with an adjustable valve in the rear line. The pedal goes to the floor and the calipers only move a tiny bit at the end of the pedal travel. I bled it every where. With the line to the front unhooked the master only moves a tiny bit of fluid, again at the very end of the travel. I watched it as I tried to again bleed the master. Any suggestions?

Sounds like a full bench bleed of the master again would be a good idea. Also, make sure the rear drums are adjusted correctly. Here is a link to your brake bleeding guide. This should help out alot.

When I bench bled the master, the rear side worked correctly and had a strong stream. The front chamber didn't push air or fluid. I guess my master cylinder has gone bad.

I replaced the Corvette master, which was bad, with a new one for a 71- early 80's chevy pickup. After bench bleeding and installing, it works great.
