The Hawk HB803D.639 ER-1 Brake Pads are high-performance brake components designed for street and endurance racing applications. Developed by Hawk Performance, these pads feature a specialized compound that delivers a higher coefficient of friction compared to standard endurance pads, ensuring improved stopping power and consistent performance under demanding conditions. Constructed with advanced friction materials, the ER-1 pads provide excellent modulation and pedal communication, allowing drivers to precisely control braking force. Their groundbreaking friction stability extends across a thermal range up to 1,600°F, making them suitable for sustained high-temperature operation. These pads are engineered to offer a balance of durability and performance, making them ideal for competitive racing and spirited driving.

Designed for 2015 and newer Ford Mustangs excluding GT350, GT350R, and GT500 models, these brake pads are a direct replacement for OEM components. They are intended for use on vehicles that require enhanced braking performance for endurance racing, track days, or aggressive street driving. The installation process is straightforward, fitting standard brake calipers without modification. The kit includes a set of front brake pads, ensuring compatibility with the specified vehicle models. Suitable for high-performance driving scenarios, these pads provide reliable, consistent braking with excellent thermal stability and fade resistance, making them a valuable upgrade for enthusiasts seeking race-level stopping power.

Overview

ER-1 has been developed by Hawk Performance for the endurance racing market with a simple goal; offer a higher coefficient of friction than competing endurance pads while maintaining matched or improved lifespan. Years of testing across America’s most prestigious races has resulted in a well-rounded compound that offers ideal modulation and pedal communication, with ground breaking friction stability across a thermal range as high as 1,600°F. This consistency of performance, hour after hour, makes it ideal for not only endurance racing, but HPDE, track days, time trials and even sprint racing.
