65 Power Brakes

[William G.]

Can't get my brakes to work -- here's what I've done.
(1) Had power brake booster rebuilt.
(2) Had dual master cylinder rebuilt.
Results -- have bled the brakes and can't get the pedal pumped up - pedal is slow coming back. No air in the line. Can't figure out the problem. Any suggestions?

Re: 65 Power Brakes

Did you bench bleed the master cylinder before it was installed?

Jim
Thanks for the reply.
I have been working on this 65 for 3 years so
I am pretty sure that i did but not 100%
Can i take it off and still bleed the master cylinder.

Thanks again
Bill

Who rebuilt your master cylinder?

Re: 65 Power Brakes

The most common problem with no brakes in a situation like this is. When you bleed the brakes, did you bleed BOTH bleeders in each of the rear calipers?
You have to let the air out of both sides of the rear calipers due to the design.
