Type 25 Clutch Master Cylinder

Replacement clutch master cylinder for Volkswagen Type 25 (T3) models. This hydraulic master cylinder is responsible for converting clutch pedal movement into hydraulic pressure, which is then transmitted to the clutch slave cylinder to operate the clutch mechanism.

Over time, clutch master cylinders can suffer from internal seal failure, fluid leaks or corrosion, resulting in a soft clutch pedal, difficulty selecting gears, fluid loss or complete clutch failure. Replacing a worn master cylinder restores proper clutch operation and hydraulic system reliability.

This economy replacement unit is supplied with the reservoir pipe bung and plastic feed pipe connection, making it ideal for routine repairs and maintenance.
