Grinding sound on left front...

Hey guys, my first post here, so I appreciate the responses in advance. First off I am not a mechanically minded car guy so please be patient with me. I recently purchased my first Jeep, a 2013 Wrangler Inlimited and I couldn’t be happier, there is just one issue I have with it.

When I brake there is a grinding noise coming from the front left tire area. I took it to a mechanic I know and he told me that whoever owned it previously had put Rubicon tires on it. From his description I believe it is the caliper making contact with the wheel. Will spacers fix this or am I going to have to buy new wheels/tires.

I searched the forum and found a few threads about this but didn’t really find an answer so if I overlooked it and am re-starting and older thread I apologize. Thanks for any advice you can provide.

Any 16-17" wheel should work with the JK brakes just fine. If you only hear it while braking I would imagine it is a worn out brake pad making contact with the rotor.


That would get you to buy new brakes not wheels/tires.

Thanks for your reply Mocs. Yeah it has 17’s on it right now. I should have mentioned earlier but both front wheels are grooved. I appreciate the advice and will definitely look at it from a brake standpoint as well.

The mechanic is full of shite if he's blaming the tires and wheels. Rubicon tires and 17" wheels are not your problem. I run a Big Brake Kit, which has far larger calipers and does require 17" wheels just to install it. If a BBK clears with 17's, stock calipers will with room to spare.

You just need new pads and rotors. 17" wheels have plenty of caliper clearance. If you had said 15" wheels, those could be rubbing slightly, but that would be all the time.

The grooved rotors mean the pads are down to the metal backing plates and that's why it grinds when you press the brake.

Do you have any mechanical aptitude? Pads and rotors are very easy to do. Pull the tire. You then need a 21mm wrench or socket for the caliper brackets or you can go with removing the caliper pins which I think is a 13mm bolt, and wouldn't be a bad idea so you can clean and grease them. Pull the caliper, remove the rotor, remove the pads, compress piston slowly as far as it goes with a clamp, place new rotor on the axle, install the pads in the caliper, bolt it back on, torque to spec and use a bit of locktite and reinstall the tire. It doesn't take me more than 30 minutes a side but I have a floor jack and air tools. Figure an hour a side if you have just hand tools.
