  • Brake noise related to worn or heat-affected rotor surfaces
  • Reduced braking consistency from a rotor below discard thickness
  • Service replacement needs on a 1979-1981 Pontiac Firebird rear brake system
  • Fitment correction when the existing rotor no longer matches OE dimensions

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center hole diameter before installation. For best results, inspect pads, calipers, and hub surfaces during brake service, and confirm the rotor meets the required discard thickness before reuse or replacement. Fits 1979-1981 Pontiac Firebird, rear.
