1981 CJ7 brake problem
Original owner,1981 CJ7, 6 cylinder, manual brakes, parked Jeep about 3 years ago, up to this time brakes worked great. Getting Jeep back road worthy but having a problem getting the brakes working normally. Brake pedal returns higher than clutch pedal height, can't remember if this is normal. When the brakes are applied, the pedal travels near the floor with just rear brakes applied, after one pump of the brake pedal good brakes are achieved and all four wheels brake. Release the brake pedal and it returns above clutch pedal height and next brake application the pedal goes near floor again and one pump good brakes again. Holding brake pedal at same height as clutch pedal, the next application brakes are good. Replaced master cylinder several times and proportioning valve several times with no change in the way brakes operate. Wondering if there was a stop under dash to prevent brake pedal returning to high or some other possible cure.
