Hydraulic Brake Cylinder Cup

A hydraulic brake cylinder cup, also known as a brake cylinder seal or brake cylinder piston seal, is a component used in hydraulic brake systems. It is typically made of rubber or other flexible materials and is designed to create a tight seal between the brake cylinder piston and the cylinder bore.

The hydraulic brake cylinder cup plays a crucial role in the proper functioning of the brake system. When the brake pedal is pressed, hydraulic fluid is forced into the brake cylinder, which in turn pushes the brake cylinder piston against the brake pads or shoes, creating friction and ultimately stopping the vehicle.

The cup ensures that the hydraulic fluid remains contained within the cylinder, preventing any leakage and maintaining the necessary pressure for effective braking. It also helps to prevent air from entering the brake system, which could lead to a loss of braking performance.

Over time, the hydraulic brake cylinder cup may wear out or become damaged due to the constant pressure and movement within the brake system. When this happens, it is important to replace the cup to ensure the proper functioning of the brakes.

In summary, the hydraulic brake cylinder cup is a vital component in hydraulic brake systems, providing a seal between the brake cylinder piston and the cylinder bore to maintain pressure and prevent fluid leakage.
