Description

What does a clutch master cylinder do?

This clutch master cylinder serves as the primary component in the hydraulic clutch system, converting the mechanical force applied to the clutch pedal into high-pressure hydraulic fluid movement. This pressure is then transmitted through the hydraulic lines to the slave cylinder to facilitate seamless gear engagement and disengagement.

Compatible vehicles and engines

Designed for heavy commercial vehicle applications, this unit is compatible with Mercedes-Benz models. It is a complete assembly, meaning it arrives factory-assembled with the housing, piston, sealing group, spring, and push rod to ensure reliable operation and simplified installation in the field.

Installation and maintenance

To ensure correct fitment during replacement, technicians should verify the mounting-hole spacing and port thread specifications against the existing unit. Maintaining a clean hydraulic system and monitoring fluid levels are essential practices to prevent air entry or seal wear within the assembly.

Selection guidance

Consult your authorized distributor to confirm exact compatibility for your specific vehicle application.
