Brake Rotor/Disc: Testing and Inspection
Brake Rotor Thickness Variation Check
Check thickness variation by measuring the rotor thickness at four or more points around the circumference Of the rotor. Use a micrometer calibrated in
ten thousands of an inch. Make all measurements at the same distance in from the edge of the rotor.
A rotor that varies in thickness by more than 0.013 mm (0.0005 inch) can cause pedal pulsation and/or front end vibration during brake applications.
A rotor that does not meet these specifications should be refinished or replaced.
