SARATH PRAKASH

Ceramic brake discs are 50% lighter than metal brake discs, reducing vehicle weight by up to 20kg. This saves fuel and reduces unsprung masses, improving shock absorption and handling behavior. Ceramic discs ensure very high and consistent frictional properties, performing well even in wet conditions where carbon/carbon discs fail. Porsche has developed new high-performance ceramic composite brake discs called PCCB that offer substantial improvements in braking technology through innovative cooling ducts for efficient cooling.
