2010 Wrangler Unlimited brake/rotor heeeelp please!

[joshp912]

I took my jeep in to have the rear brakes looked at since they were making noise when driving and even worse when stopping. The brake man told me my rear right rotor was getting torn up and needed to be replaced. I know they usually try and tell people this alot.


Are there any DIY articles around for a 2010?


Also what is the minimum size my rotors have be so i can sand them down to save some money?


Any good websites for replacement parts?



Thanks guys!

You can actually do a little "feel" check of your rotor (at least on the fronts, I have rear drum brakes). There are little spots exposed where you can run your fingers over the surface (don't do this right after driving - they will be VERY hot. Don't ask how I know:redface. If the noise is not too extreme, your rotors can probably be turned, but there may be other issues (i.e. sticking caliper). You didn't mention the mileage on your Jeep, but it seems odd you'd be having this problem on a 2010. I got about 85K miles out of my first set of pads. Rotors are relatively cheap.....calipers not so much, but when they "hang" they can cause some really serious problems.

I can't help with the DIY or websites (other than the "usual" - Quadratec, 4WD Hardware, etc.) on a Jeep so new, but I hope I helped a bit. Good luck.

Yea I put 50k on the Jeep so far...lots of driving haha. Anyways started the repair and just bought two new rotors...got em on. I just need to get a c-clamp to push back the piston on the master cylinder and i'll be in there!!!


It's so cool to do work yourself and save money on repairs!

Ok so today i borrowed a c-clamp from my neighbor and tried using it to compress the piston but the it would not budge. The piston will only go about half way back in then just seize up. I'm stumped...


Pleaaase help me!

You did remember to uncap your master cylinder and siphon out a little brake fluid,right?........Just checking. Maybe loosen the bleeder?.....but that really shouldn't be necessary. Is this the caliper where the rotor was worn? Might be your problem - bad caliper.

Sounds like that's the trouble. You can usually push the caliper back in using the handle of your hammer in the circular part so if you can't with a c-clamp, something is wrong.

Yea the brake man said my wheel was a lil warped and that's why the brakes wore out so quick.

I called the dealership and a service writer told me to take off the bolt behind the piston to let some fluid out and that it would probably go in after that...I hope so, this thing is straight jammed!

A sticking caliper will warp a rotor very quickly.....generates tons of heat (sort of like "riding the brakes"). I'm assuming when you said "wheel" you meant "rotor". And what the service writer said makes no sense.....it should push back through the lines and into the master cylinder reservoir with only a C-clamp.......unless there's something wrong with the caliper.

Not sure here so someone help me do the new jeeps come with a threaded type of caliper piston?

• On threaded-type rear calipers, the piston must be rotated to depress it. This requires a special tool.

 

[joshp912]

maybe he did mean rotor...either way i replaced the rotor. the service writer said that removing the bolt would relieve some pressure and the piston should go back in then. when i used a c-clamp it would only push the piston in about half way then it just wouldn't budge??

Very good question.....and I haven't a clue. As I stated earlier, I have rear drums. Thanks, Utah. Glad I've got an '03.

Fixed her today!!!!


Just needed to loosen this nut on the back of the calipter housing to let out some pressure for the piston to go in...went right in after that.
