Brake Rotor/Disc: Testing and Inspection
Brake Rotor Thickness Variation Check
Check the 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 in) may cause a pedal pulsation and/or a front end vibration during the brake
applications. A rotor that does not meet these specifications should be refinished to the specifications or replaced.
