Common Issues This Rotor Can Address

• Brake fade during repeated stops
• Excess brake dust buildup on the rotor surface
• Pad glazing that reduces initial bite
• Corrosion on exposed rotor surfaces
• Uneven braking feel from worn front right rotors

Installation Notes and Tips

Verify rotor diameter, thickness, hub dimensions, and caliper clearance before installation. This rotor is listed for front right use on vehicles such as 2007-2014 Chevrolet Tahoe, front right; 2007-2014 GMC Yukon, front right; and 2015-2020 Cadillac Escalade, front right, with exclusions noted for certain brake packages. Confirm the vehicle’s brake configuration, including 6-piston BBK exclusions where specified, before ordering. Replace brake pads and inspect related hardware and hub surfaces during service for proper rotor seating.

Quality Assurance
