Diagnosis And Testing - Brake Rotor: Notes
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
Any servicing of the rotor requires extreme care to maintain the rotor within service tolerances to ensure proper brake action.
Excessive runout or wobble in a rotor can increase pedal travel due to piston knock-back. This increases guide pin sleeve wear due to the tendency of the caliper to follow the rotor wobble.
When diagnosing a brake noise or pulsation, the machined disc braking surface should be checked and inspected.
