I have a 1980 CJ7 with a brake problem, I have performed the following:
New wheel cylinders, drums, shoes, hardware kits, master cylinder, (shimmed master cylinder out 3/8 inch to shorten pushrod), new calipers. Also, took it to a professional shop to fix, they eventually called me and gave up on it.
My problem is brakes take two pumps to build up a pedal, the first one goes to the floor. Once the pedal is built it seems to be solid (not spongy).
We have bled the system countless times including gravity bleeding and bench bled the master cylinder.
Jeep has over axle lift kit with brake line extensions.
