Important
When using any one of the brake labor operations listed in this bulletin (except for H9709 - Brake Burnish), the following two rotor measurements (1.
Original Rotor Thickness, 2. Refinished Rotor Thickness are required and MUST be written/documented on the repair order, or for your convenience,
complete the form (GM Brake Service Repair Order Documentation for Required Measurements) shown above and attach it to the repair order. If the
Warranty Parts Center generates a request, this Documentation/Form must be attached to the repair order that is sent back.
Important
Documentation of brake lathe maintenance and calibration as recommended by the lathe manufacturer must be available for review upon request.
Repair Order Documentation - Rotor Original And Refinished Thickness - REQUIRED
When resurfacing a brake rotor or drum, the ORIGINAL thickness (measured thickness before refinish) and REFINISHED thickness (measured
thickness after refinish) MUST be written/documented on the repair order hard copy for each rotor serviced. If a rotor replacement is necessary, only the
original thickness measurement needs to be recorded.
Repair Order Documentation - Explanation of Part Replacement - REQUIRED
If replacement of a brake component is necessary, proper documentation on the repair order is required. See the following examples:
^
Brake rotor replacement - Customer comment was brake pulsation. Rotor was refinished on a prior brake service. After rotor measurement, it was
determined that refinishing the rotor again would take it under the Minimum Thickness specification.
^
Brake pad replacement - Customer comment was brake squeak noise. On inspection, found pads contaminated by fluid leak at caliper.
