EBC HPSR Brake, the fixed version. MADE IN UK. Development goal is to improve braking performance compared to the original brake disc. EBC used HPSR low carbon steel, having a higher coefficient of friction of 18%. This steel is much more resistant to rust than cast steel. In addition, the entire surface with a 3 micron thick zinc layer is protected, the same abrades already in deceleration in the contact area of ​​the pad. Only in this area, light surface rust can form on prolonged life. The brake discs are drilled in the design of the bird's wings as far as possible to get along with how much small holes with an optimal cleaning of the brake disc of rainwater and brake dust. The fewer holes are made, the better the wet braking performance and the less abrasion. - HPSR forged steel brake ring milled with low carbon content. - Therefore, no distortion of the brake disc even at maximum load. - N vitrification of the braking surface, the coefficient of friction therefore remains constant. - Perforated braking surface with optimized hole pattern. - Galvanized for corrosion protection. - low production tolerances. - EBC recommends brake pads to ensure Sintered Double H EBC braking performance. - Standalone design.
