Disc Brakes -> AC-Delco Single Piston Rear Disc Brake (Type 2) -> Description
Vehicle: 2003 Chevrolet Impala 3.8 V6 GAS

Disc Brakes -> AC-Delco Single Piston Front Disc Brake -> Troubleshooting -> Brake Roughness
Vehicle: 2003 Chevrolet Impala LS 3.8 V6 GAS
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in disc thickness. If roughness or vibration is encountered during highway operation or if pedal pulsation is experienced at low speeds, the disc may have excessive thickness variation. To inspect for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than ...
