rubbing on the rotor

[sholady]

I have a ring rubbed on the backside of my front, right rotor. I have been having a clicking sound from the front when I turn. The sound is more prominate when I turn left and when it's cold. It's not the cv joint. I also hear a squeaking sound that I think is whatever is rubbing my rotor. The squeaking doesn't stop when I apply the brakes. Any idea? pcorn

The ring on the rotor might be from the dust (rock?) shield. It's easily bendable, and can squeak when it's rubbing the rotor.

The clicking probably IS the cv joint. Or maybe wheel bearing.

The squeak could also be a wheel bearing.

Anyone with more knowledge??

it's not the cv joint cause when i had new mufflers put on i(and the mechanic) had a good look at the while it was up on the lift.

I had the same problem, minus the clicking sound, and it was my dust shield. It had bent in and was rubbing the rotor, yet it went away a little bit when I turned. shrug

SHOLADY,

If the "ring" is in the surface area where the brake pads contact the disk surface, it is most likely caused by a small stone or road grit caught between the pad and the disk.

Try some hard braking while backing up. This will usually dislodge whatever is in there. This "grit" is usually what causes brake pad "squeeking", as well as the "grooves" (or rings)in the rotor.

Do your brake pads have a "wear indicator", that is a metal attachment that comes into contact with the disk when the brake pads are worn to a predetermined point, usually about a 1/16 to an 1/8 of an inch of pad?

These make a lot of squiking noise when they contact the rotor surface. They are intended to tell you when it is time to install new brake pads.

A slight bend in the backing plate could be mimicking a wear indicator by rubbing against the disk, as stated above.

As for the "clicking" sound, while turning, it is a classic CV joint symptom. A visual inspection of the CV joints will only tell you whether or not your CV joint boots are in good shape, i.e. no cracks, rips, tears, holes, splits in the bellows, broken clamp, etc.

Your two symptoms may NOT be related, but rather symptoms of two separate problems. Resolve your brake noises first, then if the "clicking" continues look into the possibility of a worn CV joint. rangerj

My left dust shield is bent also. It makes a grinding noise when I turn left and apply throttle. I replaced my rotors and pads a couple of weeks ago and the back of the rotor was all tore up from no pads left ( I guess I drive hard, b/c there was nothing left of the back pad shrug ). And my CV's were bad and my boots weren't torn. There was no visual indication.

SilverSHO89,

You need to check your brake calipers. First make sure your slider pins are clean and lubricated with a film of silicone grease. Clean and LIGHTLY grease the surface that the calipers slide on.

The uneven wear you describe, the inner brake pad completely worn out while the outer pad still has some "meat' left, indicates sticking slider pins and or the calipers as a whole.

If the inner pad was worn at an angle it would indicate a piston cocked in the caliper. It could also indicate a warped rotor.

So, you need to do some checking or you will be replacing your rotors and pads again soon. rangerj
