• Reduced braking consistency from corrosion on the braking face
• Rear brake service needs on GM crossover and SUV platforms
• Replacement of a rotor that no longer meets discard thickness limits

Installation Notes

Verify rear axle fitment by year, make, and model before installation. Confirm the rotor matches the vehicle’s 6-bolt pattern, 120 mm bolt circle diameter, 67.5 mm center bore, and 23 mm thickness specification. Inspect pads, caliper hardware, and hub surfaces during brake service, and clean the mounting face before installing the new rotor.
