High Performance Brake Pads for Road and Track vehicles. Cosworth's many years of Motorsport experience has taught us that stopping power is just as critical to performance as engine power. With that in mind, Cosworth has developed two lines of performance brake pads for genuine fast road car and track performance enthusiasts - StreetMaster and TrackMaster. Manufactured in the UK, Cosworth brake pads feature a 1.5mm granulated inter-layer which not only serves to act as a shock absorber, helping to reduce stress on the rotor surface but triples bonding strength, diminishing edge lifting. To reduce the bedding-in or seating-in time - this is the time it takes for the pad and disc to adapt to each other - all Cosworth brake pads are heat seared. This process heats the friction material in excess of 600 degrees C, toasting the surface, greatly enhancing the performance the first time that the driver applies the brakes. Scorching pads also significantly reduces initial fading - fading increases the necessary force and pressure required to maintain the deceleration of the vehicle. Cosworth's brake pad range offers exceptional performance without compromise. Cosworth TrackMaster brake pads offer exceptional performance for Track Day and Event drivers. With the brake pads heat seared during production, so reducing bed-in periods, TrackMaster brake pads deliver a strong braking effect through 800C consistently and reliably with a great pedal response. Track day driving Extremely high friction level 0.7µ friction coefficient Strong brake effect through 800°C "Vee" line expansion groove technology - superb debris clearance Fitted with premium quality shim hardware - silent braking technology Durability Factor 9.5 with minimal disc abrasion Super fast "bed-in" typically under 2 laps Heat stable, predictable & heat cycle exceptionally well This track formulation CAN be safely used on highways except in Europe where ECE R90 approvals are required. This pad has too much brake effect to be compliant with these regulations.
