I noticed the brake pedal travel increasing and now I find no brake fluid in the forward part of the master cylinder reservoir. Is the 1992 Cherokee brake system split front/back or is it setup up diagonally? I need to know where to begin looking for the lost fluid

! Thank you.

 

It looks like it is set up front to back . check your rear brakes for leaks .

 

You should be looking at it as half full, not half empty!



Yep, you gots leaks.

 

Probably a bad wheel cylinder, very common. If one is bad, do em both. if the shoes are contaminated, change them. Check your axleshaft seals while you are in there.

 

I have similar issue. Since this is an older post, I would start a new post but couldn't find where to do it.
Here's my similar situation. I have a 1994 Cherokee. The smaller reservoir, front, is almost empty. Is that the rear brakes? I did a drum brake job and it looked ok. My Jeep sat a bit. Had new engine mounts done. Then went to drive it, the pedal went to the floor. I suspect, bad REAR wheel cylinders. Most likely the rear if the smaller reservoir goes to the rear. Is the smaller reservoir towards the front of the Jeep for the rear brakes?

The brake fluid looked rather blackish. What is the best way to drain and purge the lines. I can use a turkey baster and empty the reservoir. Then could fill it , and open the wheel cylinders one at a time and flush thru it?
====================================
Yes, I support 2A. I always prayed never had to use it. But I did in CA (of course) where they paroled 2 felons for Homicide back in the 80s/ And are still doing it today ! . Didn't have to pull the trigger. But was so close !!
