StopTech Street Performance brake pads are manufactured using positive molding process under extreme pressure to compress the friction material and bond it to the backing plate. This process assures consistent friction material density throughout the pad, resulting in even wear and performance characteristics throughout the life of the brake pad. StopTech Street Performance are scorched; this additional process forces any impurities out of the friction material and pre-burnishes the pads to greatly accelerate the break-in process.
