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 discs
Boasts up to 10% improvement in friction effect improving brakes even further
Weight of the X and XC series is reduced by 5-10% by using a 6 only button drive system on a lightweight alloy centre hub, which once again grabs the lead over stock parts
The SD-System uses a square sided rivet with many advantages
The 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 load
This extends the lifetime of the rotor and prevents distortion failures
Keeps 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 exceeded
This 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 buttons
The 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 button
