Main components of floating type disc brakes
There are two types of disc brakes. One is called the "opposed piston type disc brakes" which has pistons on both sides of the disc rotor, and the other is the "floating type disc brakes" which has a piston on only one side. The floating type disc brakes are also called the sliding pin type disc brakes.
Derived technology of disc brakes is Magneto-rheological Brakes, named MRF Brakes. It utilizes magneto-rheological fluid (MR fluid) as the friction media instead a conventional brake pad. The discharge of electric current to the MR fluid will create magnetic field which generate friction to the rotating disc. The braking action is occurring.
Drum brakes also use friction but in a slightly different way. Drum brakes consist of a brake drum and brake shoes. The hollow drum turns with the wheel. When the brake pedal is depressed, a hydraulic cylinder pushes brake shoes with friction linings against the inner surface of the brake drum, creating friction and thereby slowing the wheel.
There are three types of drum brakes depending on how the brake shoes are pressed on to the drums; leading/trailing shoe type, twin leading shoe type and duo-servo type.
