Project Mu HC-EP Rear Brake Pads

HC-EP is a premium performance street and rally brake pad. It has more bite than NS and has excellent fade resistance. Capable of operating at temperatures up to 800 DegC, this pad will handle almost all serious braking conditions. HC-EP is a genuine 'cross over' pad that is suitable for both road and track days. HC-EP is extremely capable in competition environments, so use this pad if you are involved in a serious track day, rally and hill climb. Along with temperature capabilities, HC-EP are renowned as a 'drivers pad' with unmatched driver feel and control. The HC-EP pads provide linear control commensurate with foot pressure on the brake pedal and maintain steadfast stability in all areas.

Project Mu Pad Features:

Fade Resistance

When brake pads operate at high temperatures, high pressure gases can be created in the pad and can cause a 'gas layer' between the pad and rotor. This can make the driver feel like the brakes have lost performance as the brake pedal feels the same, but the car won't slow down as normal. This phenomenon is known as 'fade'. A slot is manufactured in all Project-Mu pads to offer the gases an escape route. Rotor slots also assist to provide the same solution.

Noise Suppression

Brake pads manufactured without a chamfer on the leading edge of the friction material, are more likely to produce unpleasant noise. This noise known as brake squeal is actually a high frequency vibration created by the friction between pad and rotor. The vibration can manifest in caliper, rotor or suspension vibration. This 'problem' is reduced or eliminated by the chamfer on the pad material. Brake squeal is more likely to occur in some models, and not others. It can also depend on the condition of the car.

Heat Treatment

Project-Mu brake pads are subjected to heat treatment as part of the manufacturing process. This process 'burns out' unwanted materials in advance, reducing the gases that can cause fade. As a result, Project-Mu brake pads only need light 'bedding in' to match the pad to your rotor surface.

Brake Pad Structural Stability

Brake pads are subjected to huge pressure from caliper pistons in unequal proportions across the pad. Brake pads must remain flat to offer optimal performance so Project-Mu use only the highest grade quality steel at the correct thickness to ensure this stability. Project-Mu pads are up to 20% stronger than some competitors.
