A motorsport master cylinder is a key component in a hydraulic brake system, which is commonly used in automobiles. Its primary function is to convert the force applied to the brake pedal by the driver into hydraulic pressure that can be used to actuate the brake calipers or wheel cylinders.
Here's a basic explanation of how a master cylinder works:
Brake Pedal Input: When you press the brake pedal in your vehicle, you are applying force to a piston inside the master cylinder. The brake pedal is connected to a pushrod, which, in turn, is connected to the master cylinder.
Piston Movement: The force applied to the brake pedal causes the master cylinder's piston to move within its cylinder. The master cylinder is typically filled with brake fluid. As the piston moves, it pressurises the brake fluid.
Hydraulic Pressure: The pressurised brake fluid is then sent through brake lines or brake hoses to the brake calliper's or wheel cylinders located at each wheel. The brake fluid transmits the force and pressure to these components.
Brake Calliper's or Wheel Cylinders:
Friction and Slowing Down: The friction generated between the brake pads and rotors (or brake shoes and drums) creates a braking force that slows down or stops the vehicle.
Return Mechanism: When the driver releases the brake pedal, a return mechanism, often a spring or a combination of springs and seals, allows the piston in the master cylinder to return to its original position. This action reduces the pressure in the brake system.
It's important to note that brake fluid is crucial for the proper functioning of the hydraulic brake system. It is designed to resist compressibility, withstand high temperatures, and provide consistent hydraulic performance. Regular maintenance, including checking and replacing brake fluid as needed, is essential for the safety and effectiveness of the braking system.
