Brake Caliper lock up

Has anyone had a problem with their brake caliper locking up one them? I have a 2007 JK Unlimited with 57,000 miles and my rear right brake caliper is locked up on it. I took it to the local dealer and they said they wouldn't cover it because it is a wearable item.
It just pisses me off that my jeep is only 3 yrs old and the caliper needs replaced already. I called around the parts stores and none of them even carry a after market replacement so I can swap it out myself unless I buy one from jeep. Does anyone know anywhere else you can order one from?

I wouldn’t think the caliper was a wearable item. Pads, yes.

Idk, but you'll likely need a new rotor too..... Stuck calipers suck

You say it's locked up, evidently it's not locked CLOSED, so it must be "non-operative"???

I'd take it off and see if the slave cylinder is frozen or if there's an "obstruction" in the pad surface

Did you check the Ebrake ???


Could be something simple and of course if it's locked closed, you shouldn't DRIVE ANY WHERE, otherwise the repair costs are going up, just what IG says

Good luck

Yep, could be mud/rocks/crud stuck somewhere, causing similar symptoms...
But I can see it not being covered by warranty... Not saying it's agreeable, just the way things seem to go. I wouldn't expect warranty to cover rotors either if they are damaged due to a stuck caliper. Unless the caliper was covered.... Read your fine print, usually it's spelled out pretty tiny, but it's there. If there is no mention of it, then push your dealer to cover it, or check with another dealer... They don't all play by the same rules

I checked for debris, the e-brake and even loosened the bleeder to try and free it up before I took it in. It isn't locked up so tight where my wheel will drag just enough that I can't turn it by hand and to cause the pads to burn if I drive more than a few miles. I guess I'll just by the caliper from jeep and change it out my self at home.

You outta take it apart and checkout the SLAVE before buying, but

If you do put a new caliper in, don't forget to bleed that one and you probably lucked out, usually the right rear brake is the farthest from the master cyl, so you'll only have to bleed that one

Good luck

Need to replace both left and right at the same time. Don't know why you can't find a reman at the Napa.

If mine were not under warranty, I would have it apart and be looking for where it is binding. My wife's PT Cruiser at 30,000 did that and my neighborhood shop replaced rotors, found where it was binding, made sure the new pads didn't bind, used a lubricant on the slides to prevent binding and the brakes have gone 70,000 miles since with no problem with the original calipers.
