Ok so recently the right front break caliper on my 91 Cherokee is not wanting to release pressure. I'm going to look at it tomorrow. But If all else fails and i need another caliper would one off of a early 90's wrangler fit it.

 

Get it from the auto parts store, they're cheap.
Edit: In fact it would be a good idea to check/replace the other caliper too.

 

just buy that from the store. I wouldn't get an old caliper off a wrangler.

 

Yes if you replace one caliper, replace the other as well!!

 

It may fit but when it comes to braking, don't go USED please. The brakes are the most important part of the vehicle and you really should get new parts when maintaining them.

brake calipers are about $25 new. No reason to go used

 

I've been told (though I haven't tested the claim) that a fatigued collapsing rubber brake line can result in calipers not releasing.

Worth a look before investing in calipers.

 

If you have driven the vehicle with that caliper sticking, you may have also damaged the brake rotor, brake pads, the brake hoses, and should definately replace the brake fluid. Always replace brake calipers in a pair. If you only do one side the opposite side is more likely to fail.

 

you can get them new on ebay for $68 for a pair i live in the uk and had a pair shipped from a ebay seller in the states worked perfect

 

This could very well be your problem

 

The caliper piston was seized. I just replaced them both. Their 20 bucks apiece at auto zone. A lot cheaper than i thought they would be. Problem solved. Thanks guys.

 

Good man. Now you're bona fide.

 

good on ya for doing the right thing. i've seen some pretty wierd stuff happen with brakes before. i saw one guy almost cut his rotor in half on a laithe. and i've seen people put brand new pads on rotors that haven't even been turned and think that it'll be ok....not the case. always replace brake parts with new equipment.

 

Don't forget to bleed the brakes after replacing your calipers!

 

X 2, All good gouge. Defintely replace both calipers if you have to replace one. Defintely buy new or rebuilt from a store (to get a warranty). Defintely check the rotors out and turn them or replace them as needed. You guys all know I will always recommend the cheapest route to fix something on your XJ but, never go cheap on brakes and always get a warranty on the parts. Of course, get a warranty on the whole brake job if you have it done for you.
