ACDelco Severe Duty Rotors are designed for high performance vehicles, off road vehicles, SUVs, trucks, and fleet vehicles. They feature a thickness variation that helps to minimize pedal pulsation, noise, and help to extend brake pad life. These brake rotors meet the SAE standard for structural integrity with OE matched material, delivering guaranteed performance.
Features & Benefits:
- Match OE vane configuration to help minimize brake wear and optimize cooling
- Damped iron metallurgy helps with noise and heat levels
- Black and gray fusion coating provides corrosion protection
- Non-directional rotation eliminates the need for unique left and right designations
- Mill balanced to minimize vibration
- 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
