Hawk HB145D.570 ER-1 Endurance Racing Rear Disc Brake Pad Set

The Hawk Performance HB145D.570 features Hawk's ER-1 (Endurance Racing) compound, a motorsport-grade friction material engineered for drivers who demand consistent, high-performance braking under sustained heavy use. These are rear disc brake pads designed for track-only applications including HPDE events, time trials, and endurance racing.

The ER-1 compound is built around a medium-to-high coefficient of friction with a specific emphasis on modulation, progressive release, and pedal communication — qualities critical for endurance-style driving where feedback and consistency over long stints matter as much as raw stopping power. The compound delivers a higher coefficient of friction than many competing pads while maintaining matched or improved pad and rotor lifespan.

Key Features:

• ER-1 endurance racing compound — ideal for HPDE, track days, and time trials
• Consistent medium-to-high friction output across a broad temperature range
• Superior pad and rotor wear characteristics for extended track use
• Emphasis on modulation, release, and pedal communication for driver confidence
• Engineered for light-to-medium weight vehicles
• Compatible with OEM-style iron/metal rotors only — not compatible with carbon ceramic rotors
• FMSI Pad Number: D537
• UPC: 840653058467

Hawk Performance is part of Carlisle Brake & Friction (CBF), a division of CentroMotion, with decades of experience developing premium friction products for both street and motorsport applications. Note: The ER-1 compound is a track-only product and is not intended for street or general road use.
