The Hawk HPS 5.0 brake pad set for Wilwood BB SL 7421 calipers uses Hawk's HPS 5.0 compound and is specified at a 0.650 thickness in the source. The HPS compound is positioned for high-performance street use, offering higher friction over stock pads, improved pedal feel, reduced noise, minimal fade under higher temps, gentle rotor wear, and lower dust generation to provide consistent braking for street-driven vehicles.
