1. Components of Brake System

2. 1. Drum brakes Drum brakes generate consistent braking force whether the vehicle travels forward or backward. This is because drum brakes generate the same braking force in either direction. Generally, this type is used for the rear brakes of passenger cars.

3. 2. Disk Brakes The brake rotor (disc) which rotates with the wheel, is clamped by brake pads (friction material) fitted to the caliper from both sides with pressure from the piston(s) (pressure mechanism) and decelerates the disc rotation, thereby slowing down and stopping the vehicle.

4. 3. Brake Booster A brake booster, also known as a 'brake servo' or 'vacuum booster', does exactly as the name suggests, it helps to 'boost' the performance of the brakes. A brake booster makes it easier for the driver to brake by increasing the force exerted without the need for additional force applied on the foot pedal.

5. 4. ABS Control Module The ABS control module is a microprocessor that runs diagnostic checks of a vehicle's antilock braking system and processes information from wheel-speed sensors and the hydraulic brake system to determine when to release braking pressure at a wheel that's about to lock up and start skidding.

6. 5. Emergency Brake Your primary brakes work through a high-tech hydraulic system and are meant to slow your car to a stop. The emergency brake, on the other hand, is designed to hold your car in place. However, if your primary brakes fail, you can use the emergency brake to slow down and stop your car.

7. 6. Master Cylinder The master cylinder, also known as the master brake cylinder, converts the pressure on the brake pedal to hydraulic pressure by feeding brake fluid into the brake circuit and controlling this according to the mechanical force.

8. 7. Brake Pedal The brake pedal is the pedal that you press with your foot in order to make a vehicle go slower or stop. When the driver puts his foot on the brake pedal, the system automatically applies the optimum pressure required to avoid hitting the car in front.

9. 8. Wheel Speed Sensors Wheel Speed Sensors measure the road-wheel speed and direction of rotation. These sensors provide input to a number of different automotive systems including the antilock brake system and electronic stability control.

10. The 3 major parts of a Disc Brake System

11. 1. Disc / Rotor The brake rotor (disc) which rotates with the wheel, is clamped by brake pads (friction material) fitted to the caliper from both sides with pressure from the piston(s) (pressure mechanism) and decelerates the disc rotation, thereby slowing down and stopping the vehicle.

12. 2. Brake Calliper The brake caliper houses your car's brake pads and pistons. Its job is to slow the car's wheels by creating friction with the brake rotors. The brake caliper fits like a clamp on a wheel's rotor to stop the wheel from turning when you step on the brakes.

13. 3. Brake Pads Your brake pads apply pressure to the rotor, which is directly connected to each wheel. This pressure creates the friction needed to slow or stop your vehicle. When the rotor slows, so do your wheels.

14. Disc Brake Components

15. 1. Piston Brake Pistons are responsible for enabling the brake pads to make contact with the brake rotor and bring a vehicle to a stop. When the brake pedal is engaged, brake fluid is sent from the master cylinder into the brake caliper, and the pistons are pushed out behind the brake pads.

16. 2. Piston Seal Piston seals or piston rings ensure fluid or other media does not by-pass the piston as the system pressure pushes the piston down the cylinder during a pressure cycle.

17. 3. Reservoir Tank Reservoir tank prevents from cavitation to occur and thus avoid problems. It maintains high radiator efficiency and control cooling system pressure by removing cavitation. As a result it regulates temperature from rising.

18. 4. Brake Shoes Brake shoes are part of a drum brake system. Brake shoes are crescent-shaped components with a rough friction material on one side. They sit inside of a brake drum. When the brake pedal is pressed, the brake shoes are forced outward, pushing against the inside of the brake drum and slowing down the wheel.
