Brakes

I have had an issue with my left rear brake over heating ever since I put my lift on last year. I am running 35" KM2s and Rebel Offroad JK Rear Brake Kit which I thought would help get rid of the problem. Anyone have a suggestion as to what I should try next?

try to check if your rear left e-brake cable is not streched,the heat could come from the parking brake drum built into the back of the rotor,some time with a lift the e-brake cables get more tension and not necesarly this thension is even on both sides.a easy solution is remove the funky "s" shape clip holding the cables on the rear floor pan,when that is removed make sure the cables don't rub on the breather line coming out of the gas tank,and check for other interference.
hope this help!

Sounds like a sticky caliper piston. Have you pulled the piston out and cleaned everything/replaced the seals?

woah woah woah woah.

a sticky caliper doesn't refer to the actual piston in the caliper. it refers to the pins on the caliper.

look where the socket is



the caliper bolts go through the pins. take the caliper bolts, pull the pins out of the rubber boots. inspect them. if they are rusty you may need to replace them. if they have lots of gunk on them i usually take a wire brush to them.

put them back in with lots of anti-sieze

Yeah and I can tell you that it is VERY rare that shops pop these out, clean them with emery cloth and then coat the snot out of them with grease(we use nickel never seize) an then reinstall. They are the reason most shops sucker people into new complete calipers.

As the other guy stated I would start with the e brake cable before anything then see if the caliper mounting bolts slide freely then last but not least would be the abs sensor and wiring. If the sensor or wires are messed up slightly they could be activating the (?) bds or whatever it's called.

Looking at these will at least save you some diagnotic fees if you still can't find the issue.

My bad guys, I have had pistons stick on me, never the sliders. Then again I clean and grease the crap out of mine with high heat copper antisieze.
