What It Helps Address

• Brake rotor rust on exposed surfaces
• Rear brake vibration caused by worn rotor surfaces
• Reduced braking consistency from rotor wear
• Brake service needs on a Mitsubishi Diamante rear axle
• Replacement of a rotor that has reached discard thickness

Installation Notes and Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. Clean the hub mounting surface thoroughly so the rotor seats flat and runs true. Inspect rear pads, caliper hardware, and parking brake components during service, and measure rotor thickness after installation to confirm it remains above discard limits.

Fits 1997-2004 Mitsubishi Diamante, rear.
