CLEANING - DISC BRAKE SHOES

WARNING: DUST AND DIRT ACCUMULATING ON BRAKE PARTS DURING NORMAL USE MAY CONTAIN ASBESTOS FIBERS FROM PRODUCTION OR AFTERMARKET BRAKE LININGS. BREATHING EXCESSIVE CONCENTRATIONS OF ASBESTOS FIBERS CAN CAUSE SERIOUS BODILY HARM. EXERCISE CARE WHEN SERVICING BRAKE PARTS. DO NOT SAND OR GRIND BRAKE LINING UNLESS EQUIPMENT USED IS DESIGNED TO CONTAIN THE DUST RESIDUE. DO NOT CLEAN BRAKE PARTS WITH COMPRESSED AIR OR BY DRY BRUSHING. CLEANING SHOULD BE DONE BY DAMPENING THE BRAKE COMPONENTS WITH A FINE MIST OF WATER, THEN WIPING THE BRAKE COMPONENTS CLEAN WITH A DAMPENED CLOTH. DISPOSE OF CLOTH AND ALL RESIDUE CONTAINING ASBESTOS FIBERS IN AN IMPERMEABLE CONTAINER WITH THE APPROPRIATE LABEL. FOLLOW PRACTICES PRESCRIBED BY THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA) AND THE ENVIRONMENTAL PROTECTION AGENCY (EPA) FOR THE HANDLING, PROCESSING, AND DISPOSING OF DUST OR DEBRIS THAT MAY CONTAIN ASBESTOS FIBERS.

INSPECTION - DISC BRAKE SHOES (FRONT)
If a visual inspection does not adequately determine the condition of lining (friction material) on the front brake shoes, a physical check will be necessary. This will require that the brake shoe assemblies be removed.
The brake shoe friction material thickness is to be measured at the thinnest point of the friction material.





The minimum front brake shoe assembly friction material thickness is 2.5 mm (0.100 inch). When the brake shoe friction material reaches the minimum thickness, the front brake shoes must be replaced.
When the front brake shoes are replaced, only brake shoes meeting the Original Equipment Manufacturer material formulation should be used. This is required to maintain the original braking performance of this vehicle.
Replace both brake shoes (inboard and outboard) on both front wheels of the vehicle whenever the brake shoes on either side of the vehicle require replacement.
If the brake shoes do not require replacement, install the original brake shoes back on the vehicle. Make sure each brake shoe assembly is returned to its original position, on the same wheel of the vehicle it was removed from.
