Never mix and match used pads and rotors. You can use NEW pads with your old rotors IF the rotors still have life left, but if you replace the rotors you should always replace the pads. Pads pick up deposits from the rotors, so if you take pads off of another car and use them on yours, they'll contaminate your rotors with the other cars deposits. You'll get sqeaks, shakes and all sorts of problems. |
