I have a 77 CJ4 with power brakes (disc and drum). it is all original with 11,000 miles on it. I sat up for 5-10 years before I got it. The brakes required a pump or two every time I stopped.
Then I blew out a brake line. Repaired that, bled the brakes, and stopping was the same (pump pump stop). I bled them a few more times, no change. I get very little fluid out of the back (proportioning valve shuts off flow to the back when it "detects" a leak). So I got a vacuum bleeder and bled another few quarts through it.
Bought a new master cylinder, and bench bled, repeated the process again.
The brakes still are soft and require a pump of two to work properly. I've checked for leaks, nothing so far.
Sometimes if a hit the brakes as hard as I can the pedal will give way the last 1/2" and give me decent braking.
Thoughts?
