Installation Notes and Tips
Verify rotor dimensions, bolt pattern, and center bore before installation. Inspect the rear brake assembly, parking brake components, and hub mounting surface for corrosion or damage that could affect rotor seating. Because this rotor is non-directional, surface orientation is not a concern during installation, but proper cleaning of the mating surfaces remains important for accurate brake operation.
