BRAKE ROTOR/DRUM INSPECTION CRITERIA (MPV EXCLUSIVE)

DESCRIPTION

When inspecting the brake rotor or drum for wear, refer to the following Inspection Procedure to determine if a rotor/drum can be resurfaced by
machining.

INSPECTION PROCEDURE

Brake Rotor Inspection:

Many rotors have been replaced unnecessarily for brake noise. If the rotors do not contain cracks or deep grooves, and the remaining rotor thickness
allows for machining, the rotors should be resurfaced.

NOTE:

Minimum allowed rotor thickness is stamped on rotor surface.
