Ok, straightforward install of PBR Axxis pads. Car at 30k miles. Non brembo. Changed the pads w/ no problems. Performed the standard break in process, twice per the instructions since I did not turn my rotors. It's now 300 miles later and I STILL have a wicked grinding noise when braking which gradually worsens as i come to a complete stop.

What's the problem? Thx in advance.

 

Oh and it seems to only be on the rear brakes. Any help would be greatly appreciated.

 

C'mon, anybody?? I am really stumped here and the sound is killing me.

 

Are there any grooves in the rotors? Check the inside of the rotor too. Maybe something like a rock got caught in the pad
