Brake caliper will not compress
« on: July 14, 2005, 07:09:37 AM »
I just recently picked up a 91 sidekick with lots of issues main right now is the brakes or lack there of (my pads where non existent). I got new pads and rotors and when I went to do the first side I could not get the caliper to compress. I released the bleeder and even removed the line, wont budge. Other side is the same way even broke a good-sized C-clamp. What is the deal / trick or do I have to buy new calipers? Thanks for any help in advance

Sounds like the calipers locked up on you.  You can rebuild them, but I would just buy two new/rebuilt ones and start over.

Yeah mine did that while it sat waiting on a transmission, got it running and it was pulling the left.  Pulled caliper off, couldn't get it to move as normal, got big channel locks nothing....by that time I was just determined, I knew I couldn't use it I just wanted to see it move.  I took a 3lb hammer...Nothing.  Blew my mind, you would think a gnome got up there and welded it or something.

A new one is only around 50 bucks anyway.... ;D

You might look at replacing the stock
2 door calipers with 4 door calipers, I
took a set off of a 4 door in the wrecking
yard, I grabbed the whole assembly that
bolts to the knuckle, I think you need the
mount to retro the biger calipers, but with
bigger tires, the 4 door calipers make a
big improvment in stopping power

Just get some loaded calipers from the auto store.  That way you get a reman caliper and pads too.  That reminds me, I gotta get 'em too.

Rather than trying to push the piston back in it would probably be easier to pump the brake pedal and push the piston out (unless its completely seized), you can get a lot of pressure in the brake system, then you can clean it up and put it back. If it doesn't come out then a rebuilt/used caliper is the way to go. Obviously you'll have to refill and bleed the brakes afterwards and ideally you should replace the seals too.

just buy new ones.. They are soo rediculously cheap that it really makes no sense to mess with them. I just redid the whole brake system on my 91 Hardtop.. It's way simplier and a time saver!

2 cents given!
