How Does a Master Cylinder Work?
The master cylinder is an important component of a vehicle’s braking system. It plays a crucial role in converting the pressure applied by the driver’s foot on the brake pedal into hydraulic pressure, which is then used to operate the brakes.
Inside the master cylinder, there are two pistons: the primary piston and the secondary piston. The primary piston is directly connected to the brake pedal, while the secondary piston is responsible for generating hydraulic pressure. When the driver applies pressure to the brake pedal, the primary piston moves forward, compressing the brake fluid inside the master cylinder.
This compression of the brake fluid creates hydraulic pressure, which is then sent to the brake lines. The hydraulic pressure is distributed evenly to all four wheels through the brake lines, activating the brake calipers or wheel cylinders. As a result, the brake pads or brake shoes are pressed against the rotor or drum, creating friction and slowing down or stopping the vehicle.
The master cylinder also has a reservoir that stores brake fluid. This reservoir ensures that the master cylinder is always supplied with an adequate amount of brake fluid to generate hydraulic pressure. Furthermore, the master cylinder is equipped with seals and valves that prevent any leakage of brake fluid and maintain the integrity of the braking system.
- The primary piston is connected to the brake pedal.
