I have getting a squeal from my rear brakes and and I trying to figure out the exact issue. When the car and wheels are freshly washed, no issue. Even had my mechanic take a look the day after the car was washed, and he said they appear to be fine. Full brake pads and the rotors seemed to have no major issue (said I might want to consider replacing next time I do the rear brakes). After a few days of driving, the noise came back. I am wondering if the pads are the issue and the brake dust is causing the squeal. Anyone ever experience a similar issue?

 

I have had this from time to time, it gets solved by hitting the brakes hard a few times in a row at highway speeds.

 

Pads are glazed with the rotors....it happens on sports cars like this.....Do a few hard stops from say around 70mph down to 30...real hard..get ABS going as you've got to heat up the brakes and transfer some pad material to the rotor.

 

Thanks for the help. I am off to try this.

 

I have noticed my rear brakes squealing since having my front brakes (rotors and pads) changed at 30k, I will also try the remedy on my Thanksgiving drive and post my results.

I thought it was because the front breaks are new and pressing harder on the rotors than the rear pads on their respective rotors, and the lighter pressure causes the noise. Or am I wrong?

When I stomp on the breaks instead of smoothly pressing, the squeal stops quicker.
