NRS™ is a patented process for the surface modification of disc brake backing plates, adding a consistent matrix of raised st ... eel hooks that facilitate a mechanical bond between disc brake plate and friction materials. The NRS™ hooks provide mechanical bonding while exceeding industry requirements for heat, shear and environmental delamination protection. This attachment technology enables us to use galvanized steel capable of standing up to the challenging elements in the braking environment resulting in a backing plate that fully answers the corrosion problem facing automotive braking today. With a ZERO Failure Rate on over 1,000,000,000 units globally, all since its launch in 2001, the PACE Award Winning NRS is the most advanced mechanical attachment technology in the world. Originally used on those platforms where extreme performance was the standard, NRS™use has evolved to capture the full range of safety it provides to all vehicle classes. read more
