ACDelco Professional Disc Brake Rotors provide reliable vehicle braking power and are an ideal premium aftermarket replacement for your GM or non-GM vehicle. They feature a thickness variation that is less than 0.0004 to minimize pedal pulsation, noise, and help increase brake pad life. These rotors meet the SAE standard for structural integrity with OE matched G3000 qualified material delivering guaranteed performance.

Features & Benefits:
  • Inspected for balance; helping with smooth brake operation and noise levels
  • Independently tested for Noise/Vibration/Harshness (NVH) and durability/wear testing; resulting in high quality, reliable rotors
  • Follows original manufacturers' designs for dispersing heat, helping to prolong pad and rotor life
  • Ready to be installed right out of the box – no machining required
Installation Tips
  • Always replace Brake Pads and inspect Calipers and Brake Hoses when installing new rotors
  • Suspend the caliper from the suspension using a Caliper Hanger to prevent damage to the brake hose
  • After removing the old rotor, clean the hub face with a Wire Brush to remove rust buildup and apply Copper Anti Seize to prevent future buildup. Rust or debris on the hub can cause rotor runout and lead to wheel vibration
  • Apply Brake Lube to caliper pins, clips, the edges of the brake pad mounting tabs, and the back side of the brake pads to ensure noise free braking. DO NOT apply lube to the friction side of the brake pads
  • Use a Caliper Piston Compressor to retract the caliper piston(s) and make room for the new, thicker brake pads
  • Open the master cylinder reservoir during piston compression to prevent pressure buildup. Keep an eye on the Brake Fluid level to ensure it does not overflow
  • After the job is complete, pump the brake pedal several times to push the caliper piston back up against the pads to ensure proper brake function
