Automobile Braking System Pdf | Types of Brakes

What Is Automobile Braking System?

Automobile Braking System is a System which is used for Retardation or to stop vehicle by vitue of Friction.

It is important part in Automobile. It works against momentum kinetic energy of vehicle.

The main aim of the brake system is to reload vehicle or to stop vehicle. It is also used to stop vehicle on inclined surface against gravity.

Brake torque is amount of torque applied by shoe on brake drum or disc.

It is important that vehicle should stop at less distance without skidding of tyres.

Working principle Of braking System:

Brake works on the principle of Friction. Which states that two bodies in contact with each other having relative motion between them offers resistance force to the motion because of surface properties known or Coefficient of Friction.

In this Case brake drum or disc is in motion & Brake shoes are stationary.

When we apply brake, brake shoe & Brake drum are comes in contact with each other, Then Due to the frictional resistance, kinetic Energy of brake drum is converted into the heat & Motion of the vehicle gets show down or it gets stopped.  

Types of brake:

The Classification of Braking system on different aspects are as follows:-

1) AS PER ACTUATION:-

  1. Mechanical Brake
  2. Hydraulic Brake
  3. Pneumatic or Air Brake
  4. Electrical Brake
  5. Vacuum Brake
  6. Magnetic Brake

2) AS PER APPLICATION:-

  • Hand Brake or Parking Brake
  • Foot Brake or Service Brake  

3) AS PER OPERATION:-

  1. Power Operated Brake
