Thickness Variation
If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness variation. 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 .0005 inch, replace the disc.
Lateral Runout
Excessive lateral runout of braking disc may cause a knocking back of the pistons, possibly creating increased pedal travel and vibration when brakes are applied.
Wheel Bearing Looseness
