Brake Rotor/Disc: Initial Inspection and Diagnostic Overview
1. Inspect the disc brake caliper and mounting for loose or damaged parts. Make sure the disc brake caliper anchor plate bolts are tightened to
191-259 Nm (141-190 ft. lbs.).
2. Check the front brake hose and front disc brake caliper fitting for leaks or damage.
3. Check the disc brake caliper closely for wet areas that might indicate a leaking seal.
4. Measure front disc brake rotor thickness, parallelism and runout carefully.
5. Resurface, recondition or replace the front disc brake rotor. A visual inspection will not determine the required service unless the damage is
obvious.
6. Check for brake fluid contamination when inspecting the brake shoes and linings. This can indicate a leaking piston seal assembly. If a seal is
leaking, the disc brake caliper must be disassembled and inspected.
7. Check for even wear from side to side. If the set of brake shoes and linings on one side of the vehicle is excessively worn, the piston might be
seized in the bore. If a seized piston is suspected, the disc brake caliper must be disassembled and inspected.
