Brake pads are the most frequently replaced components in a
braking system. This is because they are the parts that come into
contact with the rotor, and the resulting friction can slow down
your vehicle and bring you to a stop. Brake pads also typically
include spacers and abutment clips to prevent braking noise and
ensure consistent, smooth and even braking. Brake pads are
available in a variety of friction material formulations and
quality grades, and the service life of the brake pads depends on
the composition and design of the brake pads.
