OVERVIEW

The Project Mu HC M1 Rear Brake Pads represent the flagship street-to-track model in the HC series. Specially engineered to offer premium linear pedal control, this compound delivers exceptional and stable stopping power across intense high-temperature cycles. Formulated using an advanced super graphite metallic matrix, the HC M1 focuses on minimizing brake dust creation while maintaining high-end circuit-level performance.

FEATURES

• Sold as a Complete Rear Axle Set (Left and Right)
• Linear Pedal Control: Delivers an exceptionally predictable pedal response that mirrors driver input from cold start up to track-level hot laps.
• Low Dust Performance Compound: Engineered specifically to dramatically reduce brake dust generation compared to traditional high-friction metallic track pads.
• Central De-Gassing Slits: Built-in ventilation paths efficiently discharge hot friction gases and combustion residue to eliminate pad fade during demanding braking zones.
• Precision Chamfered Edges: Cleanly radiused pad corners suppress high-frequency structural vibration and edge squeal during light braking application.
• Pre-Scorched Matrix: Factory heat-treatment burns off manufacturing impurities in advance, preventing premature fade out of the box and ensuring an easy break-in process.
• Reinforced Backplate Support: Built using specialized steel plates engineered to be 20% stronger than standard factory backplates, completely eliminating flexing under high pedal pressures.
