What This Rotor Helps Address

  • Brake noise related to a worn or uneven rotor surface
  • Reduced braking consistency from a rotor at or near discard thickness
  • Service needs on rear brake systems for Pontiac Solstice and Saturn Sky models
  • Replacement of a conventional solid rear rotor with OE-style dimensions

Installation Notes and Tips

Confirm rotor diameter, bolt pattern, and overall height before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake pulsation, and inspect pads, caliper hardware, and wheel bearings during service. After installation, follow the vehicle manufacturer’s brake bedding procedure for proper pad and rotor seating.
