Disk and Drum Brake

In most of mechanically moving item there is a mechanism installed whose main purpose in to stop the motion of that item when required. This mechanism is called braking mechanism. They are design to stop the motion of vehicle (type of motion of the vehicle does not matter) and it does so by producing friction between its components. Friction produce by the braking system uses the energy present in moving body resulting in decrease in speed of vehicle and finally stop of motion of body. Kinetic energy of vehicle which is utilized by the friction of brake is converted into heat and that heat is them move to the surrounding atmosphere.

Types of Brake

There are two basic types of braking system

1. Disk Brake 

2. Drum Brake

Disk Brake

Disk brake system consists of two main parts, one is called rotor and other is called pad. Working of disk is starts when operator applies pressure on hydraulic pad of which transfer pressure to the pad of the brake. Pad of the braking system convert that pressure into force applied on the rotor. Rotor is attached to the moving part or part responsible to providing motion to the system. Force applied on rotor force it to stop resulting in the decrease or stoppage of the body (R.S. Khurmi & J.K. Gupta 2005). 

Advantages of Disk Brake

1. Simple design of disk brake means easy to install and removal

2. Less no of parts of disk brake means it is easy to manufacture and so it is cost effective

3. Less parts and simple design means easy inspection

4. Less weight and parts make it an effective system

5. Disk brake is completely self-adjusting system.

Drum Brake

Drum brake consist of two main components one is the drum and other is the set of shoes. Working of the drum brake system starts when the operator apply load on the pair of shoes through hydraulic or wire system. Force provided to the shoes is used by them against the walls of the drum which is attached to the moving part or part responsible to providing motion to the system. Force applied on drum force it to stop resulting in the decrease or stoppage of the body (R.S. Khurmi & J.K. Gupta 2005).
