So I've been having this problem after upgrading my master cylinder and brake booster on my 1991 xj to a master cylinder and brake booster off a 2000 Grand Cherokee ! I will start driving the Jeep and everything is fine at first then after 15 to 20 minutesof riding the brake pedal starts to get super hard and the brakes start to drag almost like I'm losing vacuum or boost.This is the second master cylinder and brake booster is put in just to eliminate this problem and it has the same symptom as the last, I measured both boost shaft to brake pedal and they were both the same length so it wouldn't be caused by that? the jeep was not doing this before I did the upgrade. and everything that has to do with the system is new Everything!!! - the Proportioning Valve !?:flamemad::flamemad:
