EBC MD4155XC XC Series Contour Brake Rotor

XC-Series Contour Rotors, Rear


Concours 14/ABS/08-14
The steel used in the EBC® rotor blades is a special stainless blend with higher friction effect than normal heat-treated stainless steel found on stock discsBoasts up to 10% improvement in friction effect improving brakes even furtherWeight of the X and XC series is reduced by 5–10% by using a six only button drive system on a lightweight alloy center hub, which, once again, grabs the lead over stock partsThe SD-System™ uses a square sided rivet with many advantagesThe SD-System™ of square sided buttons means that the rotor can expand inwards and outwards unrestrained and that perfect rotor functionality is retained at any speed or loadThis extends the lifetime of the rotor and prevents distortion failuresKeeps the rotor blades perfectly true and flat throughout their life cycle and technically the only reason for a rotor to need replacement will be impact damage or over a very extended number of miles possible rotor wear limits being exceededThis means that a rotor equipped with the EBC® Brakes SD-System™ could last 5–10 times as long as a conventional rotor built with circular buttonsThe drive forces under braking are transmitted over a line contact on the square side of the button compared to the point contact of a circular buttonMaintains close tolerances of the rotor in the drive direction over a far longer period thereby extending rotor life
