Ok so on my second leg journey of my trip this weekend to my buddy's in la. I was coming home. Didn't hit the brakes at all the whole way down the i15 until I got off the freeway brakes were ok I start to get on the windy hilly part of the road home ad the pedal is soft! Not super soft just the first part of the travel where it's normally firm is just free play. Thankfully I was able to make it home in once piece thanks to downshifting. So I parked it last night( early this morning really) and looked at it just now after work the rear drums are dry the hose and line is ok the passenger caliper and line is fine and dry. Get to the driver side everything is clean looking! It's brake fluid I figured he'll I popped a hose no big deal popped the hood check the master and its full! Clutch master is full! All under the brake master is soaked. I cleaned it off and started it up the pedal feels ok now and can't find a leak or a loss of fluid! Is my jeep possessed ?

 

I'm thinking its water absorbed into the fluid boiling off. The fluid looks dirty and kind of marbled I think I will flush the system and clean up the master and the seal on the lid

 

since its a 1988 it could have the Bendix Abs system.... does your Jeep Abs?

 

Sounds like a bad seal on the booster either between the body and booster or booster and master. Good luck.

 

Brake fluid under master on booster ,replace it .

 

One would think huh?

 

No abs on it.

 

It's not like its leaking from the booster seal or any where on the master the lid was covered and so was the master like it lost the seal on the lid

 

Your gonna want to get a high ranking priest to perform an exorcism on that possessed xj pronto....the power of Chrysler compels you!

 

OK i repalced brake fluid today at work with dot 4 thats what we use. all is fine now execpt my master cyl lid wont seal tightly in the front agmst the resivior what do i need to do to make it tight because it leaks from the seal
