The Service Brake Piston converts hydraulic pressure into mechanical movement that activates the braking mechanism within the braking system. It moves forward when hydraulic pressure is applied, creating the force required to engage braking components and slow or stop rotating parts. It helps deliver controlled braking performance by responding accurately to hydraulic pressure changes during operation.Attributes:• Helps control the speed of rotating components during braking.• Assists in delivering accurate braking force based on pressure input.• Supports consistent braking response when pressure is applied.Applications: The Service Brake Piston is located inside the service brake assembly, where it moves under hydraulic pressure to apply braking force that slows and stops rotating components.
