Hydraulic Brake System

The Hydraulic brake system is a braking system which uses brake fluid usually includes ethylene glycol, to transmit pressure from the controlling unit, which is usually near the driver, to the actual brake mechanism, which is near the wheel of the vehicle.

The most common arrangement of hydraulic brakes for passenger vehicles, motorcycles, scooters, and mopeds, consists of the following

• Brake pedal or Brake lever
• Pushrod, also called an actuating rod
• Reinforced hydraulic lines
• Rotor or a brake disc or a drum attached to a wheel
• Master cylinder assembly includes:
    Piston assembly is made up of one or two pistons, a return spring, a series of gaskets or O-rings.
    Fluid reservoir
• Brake caliper assembly usually includes:
    One or two hollow aluminum or chrome-plated steel pistons called caliper pistons.
    Set of thermally conductive brake pads.

A glycol-ether based brake fluid regularly loads the system or some other fluids are also used to control the transfer of force or power between the brake lever and the wheel.

The automobiles generally use disc brakes on the front wheels and drum brakes on the rear wheels. The disc brakes have good stopping performance and are usually safer and more efficient than drum brakes. The four wheel disc brakes are more popular, swapping drums on all but the most basic vehicles. Many two wheel automobiles design uses a drum brake for the rear wheel.
