CALIPER (MERCEDES ATEGO L/H)

The brake Caliper plays a central role in a disc-brake system and has two
functions. First, it acts either as a bracket to support the brake pads on either
side of the brake disc. The second, it uses pistons to convert pressure exerted
when the foot brake is applied and clamps the brake pads against the brake disc
to slow the wheels speed and bring the vehicle to a stop.
