Components of Mechanical Brake System
Mechanical brakes are a type of braking system that relies on mechanical components to generate friction and slow down or stop the rotation of a vehicle’s wheels. So the components of Mechanical Brake Systems are-

1. Brake Pedal
The brake pedal (in cars) or brake lever (in bicycles and motorcycles) is the interface that the driver or rider uses to initiate the braking action. When the pedal or lever is activated, it sets the braking system in motion.
2. Brake Drum or Rotor
The brake drum or rotor is a rotating component attached to the wheel. In drum brakes, the drum provides the surface against which the braking action occurs. In disc brakes, the rotor serves the same purpose.
3. Brake Shoes
In drum brakes, brake shoes are curved components lined with friction material (brake lining). In disc brakes, brake pads are flat plates made of friction material. These components are pressed against the drum or rotor to create friction and generate braking force.
4. Caliper (Disc Brakes)
In disc brake systems, a caliper houses the brake pads and is responsible for squeezing them against the rotor. The caliper can be either fixed or floating, depending on the design.
5. Wheel Cylinder (Drum Brakes)
In drum brake systems, a wheel cylinder is used to push the brake shoes outward against the brake drum. It is a hydraulic component that converts the force from the brake master cylinder into mechanical force at the brake shoes.
6. Master Cylinder
The master cylinder is a hydraulic component that converts the pressure applied to the brake pedal or lever into hydraulic pressure. This pressure is then transmitted to the wheel cylinders (in drum brakes) or calipers (in disc brakes).
7. Brake Fluid
Brake fluid is a hydraulic fluid that transmits the pressure generated by the master cylinder to the wheel cylinders or calipers. It is crucial for the proper functioning of hydraulic brake systems.
8. Brake Lines and Hoses
Brake lines and hoses transport brake fluid between the master cylinder and the wheel cylinders or calipers. They need to be strong, flexible, and resistant to brake fluid to ensure reliable brake performance.
9. Return Springs
Return springs are used in drum brake systems to retract the brake shoes when the braking force is released. This prevents continuous contact between the shoes and the drum, reducing unnecessary wear.
10. Adjustment Mechanism
Some mechanical brake systems, especially drum brakes, include an adjustment mechanism to compensate for wear and maintain optimal braking performance over time.
