PFC Brakes has been chosen as the official brake supplier to Renault Sport Technologies for its new Clio RS R3T rally car.
PFC says it has developed a durable brake system able to withstand the high loads and temperatures generated in rallying. Piston cap insulators reduce temperature transfer to the brake fluid by as much as 55˚C thus minimizing the risk of boiling fluid. Larger and wider front discs are specified for tarmac to improve heat dissipation, even under increased loads such as those experienced on long asphalt stages.
A derivative of its ZR34 caliper – the forged monobloc aluminum caliper, which provides a good blend of weight and stiffness – has been specified. The pad is designed with a larger radial depth for a bigger contact area, to deliver better stopping power than the standard size typically used by competitors, PFC claims.
Testing was carried out on a variety of surfaces, which led PFC to choose two compounds to satisfy the demands of drivers of all abilities, on all surfaces. The compounds provide improved bite, modulation and release characteristics while one of the compounds has particular resistance to wheel locking.
To enable drivers to use the brakes right from the start of a stage, the brake pads are designed to work at low temperatures and the unique metallic matrix construction ensures consistency for the duration of a stage.
