Product Description

The Hawk HB151E.505 Blue 9012 Rear Brake Pads are engineered for classic Mazda RX-7 (FB) models from 1981 to 1985 with factory rear disc brakes. Featuring Hawk's Blue 9012 medium torque compound, these pads offer a balanced combination of intermediate initial bite and strong mid-range friction, making them well-suited to road racing, rally stages, and competitive driving environments where consistent braking performance is essential.

This endurance-oriented pad material is easier to bed in and delivers excellent pad longevity and rotor life compared with more aggressive compounds, while maintaining predictable modulation across a wide temperature range. The pads fit directly into OEM rear calipers with a 0.505" thickness and include the necessary hardware for a proper install, making them ideal for motorsport enthusiasts rebuilding or upgrading their braking system for performance use.
