You should be able to tell just by looking at the pads through the wheel spokes.
well they said my rotors were fine....that they weren't "cracked" or anything.what do you mean they didnt install them?? yea youll see the pad, maybe its the rotors. im actaully having an issue but i wont be able to tell until after new brake pads . i think my problem is the rotors cuz there were a few times where i had to use my breaks at high speeds and my rotors feel warped. For now more engine breaking!!!
