There are two main types of brakes found on cars and trucks:
Disc brakes
Drum brakes.
Disc brakes comprise a rotor and a caliper, while drum brakes feature a backing plate with brake shoes. Brake pads are essential components of both discs as they help to rotate the wheels.
Whereas an axle is responsible for holding the wheels in place and allowing them to rotate. This rotating force is transmitted from the engine or motors to the wheels.
