Hawk HB101D.800 ER-1 Ferro-Carbon Motorsport Brake Pads

The Hawk Performance HB101D.800 ER-1 is a purpose-built endurance and motorsport brake pad featuring Hawk's proprietary Ferro-Carbon friction compound. Engineered specifically for the demands of sustained high-performance driving, the ER-1 delivers groundbreaking torque consistency and exceptional pad and rotor longevity — making it the first aftermarket compound designed to meet the rigorous wear rates required for endurance racing without compromising stopping power.

With a coefficient of friction above .45μ across a 400–1,600°F operating range, the ER-1 maintains consistent medium-to-high friction even under the most punishing track conditions. The optimal operating window of 700–1,100°F ensures reliable bite whether you're in the early laps of a track day or the final hours of an endurance race.

Key Features:

• Proprietary Ferro-Carbon friction formulation for superior wear rates and consistent torque
• Specific emphasis on modulation, release, and pedal communication
• Operating temperature range: 400–1,600°F; optimal range: 700–1,100°F
• Higher coefficient of friction than competing endurance pads with matched or improved lifespan
• Ideal for light- to medium-weight vehicles in endurance racing, HPDE, track day events, and time trials
• Superior pad and rotor wear compared to standard motorsport compounds
• Compatible with iron/metal rotors only — not for use with carbon ceramic rotors
• Sold as a set

Developed through rigorous testing on in-house dynamometers and validated under real-world motorsports conditions, the ER-1 is equally well-suited for dirt and circle track, sprint racing, and high-performance driving events. The 0.800 inch pad thickness (HB101 application) provides ample material for extended sessions on track.
