My 2003 S430's front right brake is making extremely loud noises when a certain brake pressure is applied. Only the front right is making the high pitched noises. I have checked the pads and the rotors aren't warped, the pads has 5000 miles on them. Anyone know a fix for that? Besides being very annoying, the brakes work fine.

 

I have had this problem before. What kind of pads are you using? If you did the work yourself I would just jack the car up and remove the pads and inspect them, the retaining clips and pins and make sure everything is not damaged, then put some brake pad lube or whatever you use. Sometimes just one small error even under or over tightening the caliper pins can cause a lot of problems.

 

I'm not sure who did the brake job, but when I bought the car few months ago (From a dealer, Not Mercedes) it was like that. I'll take at look at it this weekend. Thanks!!
