Hawk Brake Pad ER-1 HB399D.630

Developed by Hawk Performance specifically for endurance racing, ER-1 brake pads deliver a higher coefficient of friction than competing compounds while maintaining equal or improved lifespan. After years of rigorous testing at top-tier U.S. racing events, ER-1 offers exceptional modulation, pedal communication, and groundbreaking thermal stability up to 870°C (1600°F). Consistent performance lap after lap makes it a top choice for endurance racing, HPDE, track days, time trials, and even sprint racing.

• Specific emphasis on modulation, release, and pedal communication
• Ideal for light-to-medium weight vehicles in HPDE, track days, time trials, or endurance racing
• Higher coefficient of friction than competing endurance pads, with matched or improved lifespan
• Superior pad & rotor wear
• Consistent medium-to-high friction
• Medium to high torque
• Not compatible with carbon ceramic rotors
• Designed for use with Iron/Metal rotors
• 200–870°C (400–1600°F) operating temperatures
• 370–590°C (700–1100°F) optimal temperatures
