Cleaning and Inspection

Caution: The rear disc brake rotors used on this vehicle are made from aluminum. For this reason, only Mopar Original Equipment Manufacturer (OEM) replacement brake shoes using the OEM friction material are to be used when brake shoe replacement is required. If brake shoes using friction material other then the OEM friction material are used with the aluminum rotors, severe scoring of the rotor braking surfaces will occur. If the braking surfaces of the rotor become scored replacement of the rotor will be required. The rear disc brake rotor used on this vehicle can not be machined.

To check the amount of lining wear, remove the wheels and tires.
If a visual inspection does not adequately determine the condition of lining (friction material) on the rear brake shoes, a physical inspection will be necessary. This will require that the brake shoes be removed from the rear caliper. Refer to Removal and Installation for the removal procedure.
The combined thickness of the brake shoe backing plate and the friction material is to be measured at the thinnest point of the combined thickness.

Brake Shoe Thickness Measurement:

The combined minimum thickness of the rear brake shoe backing plate and friction material is 7.0 mm (9/32 inch). When the combined thickness of the brake shoe backing plate and friction material reaches the minimum thickness specified, the rear brake shoes must be replaced.
Replace both brake shoes (inboard and outboard) on both wheels whenever the brake shoes on either side of the vehicle are replaced.
If the brake shoes do not require replacement, install the original brake shoes back in the caliper. Make sure each brake shoe is returned to its original position on the wheel of the vehicle that it was removed from.
