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 from the front caliper. See Removal and Installation for the removal procedure.
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. See Specifications for the replacement brake lining requirements.
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.
