This is about my 97 Cherokee, but it should apply to about any other vehicle made from the 80's through the late 90's. I'm working on my 97 Cherokee, no abs, front disk, rear drums. I'm asking here because I know there is alot of collective experience that I trust.
About two weeks ago, I lost all of my braking. No loss of fluid, so I assumed it was fluid getting past a piston. The fluid in the reservoir was black and smelled like rubber. I made the assumption that the master cylinder was bad and replaced it. After bleeding the brakes (and completely flushing the system), they were great for about 3 weeks. Firm pedal, less than an inch of travel before before the brakes engaged.
Yesterday the pedal got soft and travel increased a great deal. I can still lock the front disks up in my gravel driveway and based on the skid marks, they look like I'm getting pretty even pressure on both sides. Would this indicate a problem in the rear?
With 300,000 on the Jeep, I was planning on overhauling the brakes before this happened. Right now I've got new soft lines, calipers, pads, and rotors for the front and so far new softline, wheel cylinders, and hardware kit for the rear. I still need to order the drums and pads.
I'm not losing a drop of fluid. I even made a marker mark on the reservoir and the level does not move from that spot when it's cold.
Any suggestions or should I just keep working through the system?
