Right rear caliper may be stuck on my car. Just one of the pads disappeared really quickly. The pad on the opposite side of the rotor is still thick, and all the other brakes are wearing normally. The sliding pins that the caliper mounts too feel nice and fluid. The only abnormal thing about the caliper is a rip in it's boot. I guess the caliper just needs to be replaced, because what else could it be? My brakes are kind of spongy, but I figured that was just from a bad bleed... Can a master cylinder with damaged seals cause problems at just one wheel?

 

At 144K mi. , my rear calipers were replaced with remanufactured ones.
The hand brake was frozen on one side.

 

^Like he said, it's usually the parking brake cable that freezes. That ripped boot is also a problem, however. It's a dust boot, but once it's torn dirt, dust, and rust will destroy the lip seal and the piston won't retract smoothly or at all.

Unfortunately, I don't believe there is a rear caliper rebuild kit available; you'll have to replace the whole thing. Let us know if you do find rebuild parts. Good luck!

 

not really. you probably just need a new caliper. the spongey feeling could be from old stock brake lines or an air bubble in there.

you do know that you need a brake caliper tool that spins the piston as it pushes it back in for the rear brakes right? you cant just put a c clamp on the rear pistons cause you will damage the e-brake auto-adjuster in there if you push them strait back. is it nice and smooth when you try and push the piston back in? or does it grind or stick?

 

no there is a rear caliper repair kit from ecs, go on the site and select your model and then click on braking then hit ctrl-f and put in Hydraulic:Hardware/Rebuild Kits it's only 10 bux for both sides and i need it myself lol. i hope your piston is still good. can you screw your piston back in? i'd try taking the piston out, cleaning it and grease it. it should keep it going for a while if you're low on money

 

Thanks guys, just wanted to make sure I wasn't missing something obvious. Yeah I'm up to speed on needing to screw it in. I just ordered a new caliper from PureMS becuase i'm short on time and patience right now. Cheap rotors, Mintex pads, wiper blades, and oil filters on the way too whoo hoo.
