Cleaning and Inspection

LINING WEAR
If a visual inspection does not adequately determine the condition of the lining, a physical check will be necessary. To check the amount of lining wear, remove the wheel and tire assemblies, and the calipers. Remove the front disc brake shoes. Refer to Disc Brake Pad Rear Removal.

Material Thickness
The combined brake shoe and lining material thickness should be measured at the thinnest part of the assembly. When a set of brake shoes are worn to a total thickness of approximately 9.0 mm (3/8 inch) they should be replaced. Replace both brake shoe assemblies (inboard and outboard). It is necessary that both front wheel sets be replaced whenever brake shoe assemblies on either side are replaced.

If Replacement Is Not Required
If the brake shoe assemblies do not require replacement, reinstall, the assemblies making sure each brake shoe is returned to the original position. Refer to Disc Brake Pad Front Installation.
