The brake pad is a vehicle part which converts kinetic energy into thermal energy due to the force applied to a brake disc or drum, decelerating the vehicle.

EHWA developed the so-called BSL wheels ("Brazed Single Layer")- and conventional electroplated wheels for the surface processing of brake pads. With the BSL coating, the grits are brazed onto the grinding wheel in a single layer.

With this type, significantly longer tool lifetimes are possible compared to electroplated grinding wheels. In addition to the coating type, specially coated grit types are also good solutions to increase tool life and grinding performance.
