Slave cylinders are a critical component within the hydraulic brake and clutch systems of passenger cars and commercial vehicles. Located near the brake calipers or clutch release fork, these cylinders receive pressure from the master cylinder and translate it into mechanical force to engage the brakes or disengage the clutch. They utilize a piston and seal assembly within a cylinder bore to amplify the hydraulic pressure, ensuring efficient and reliable operation. Common failure points include seal degradation leading to fluid leaks and reduced braking/clutch performance. Examples in this Brakes > Brake Controls > Slave Cylinder category include Bosch slave cylinders (MPN KS00003312), Febi units (MPN FEBI12333), and heavy-duty options from MAN (MPN 81.51101-6509 and 81.51101-6508).
