EBC HPSR brake disc, fixed version. Made in the UK. The goal in the development is to improve the braking performance compared to the original brake disc. EBC used low carbon HPSR steel, having a high coefficient of friction of 18%. This steel is much more resistant to rust than cast steel. In addition, the entire surface is protected with a 3 micron thick zinc coating, which abrades itself already during deceleration in the pad contact area. Only in this area, light surface rust can form after prolonged use. The brake discs are drilled in bird's wings design as far as possible to get along with the fewest number of holes with excellent cleaning of the brake disc of rain water and brake dust. The fewer holes are placed, the better the wet braking performance and less wear. - Brake ring in forged HPSR milled steel with low carbon content. - Therefore, no distortion of the brake disc even at maximum load. - N vitrification of the braking surface, friction coefficient, therefore, remains constant. - Brake surface drilled with optimized drilling pattern. - Galvanized for corrosion protection. - lower manufacturing tolerances. - EBC recommends brake pads to ensure EBC Double H sintered braking performance. - Autonomous drawing.
