Hawk HB921P.670 SuperDuty Ferro-Carbon Rear Disc Brake Pads

The Hawk HB921P.670 SuperDuty brake pads are engineered for extreme braking performance under the most demanding conditions. Featuring Hawk's proprietary Ferro-Carbon friction material, these severe-duty brake pads are specifically designed for professional truck fleets, commercial vehicles, and trucks and SUVs that frequently tow or haul heavy payloads.

Key Features:

• Ferro-Carbon friction material engineered for severe-duty applications
• Extremely high coefficient of friction for maximum stopping power
• Superior resistance to brake fade under high temperatures and repetitive braking
• Unmatched performance under high inertia and heavy load conditions
• Extended pad and rotor life compared to OEM brake pads
• Designed and manufactured in the United States
• Compatible with iron and metal rotors (not for use with carbon ceramic rotors)

When towing heavy trailers or carrying substantial payloads, braking systems experience significantly higher temperatures that can cause premature pad wear and dangerous brake fade. The SuperDuty compound delivers consistent, stable friction even under extreme thermal stress, providing the confidence and safety you need when operating at maximum vehicle capacity. These pads are factory burnished but should be properly bedded-in with your rotors to achieve optimal performance and create the proper transfer film at the pad-rotor interface.
