Type 25 Clutch Master Cylinder - ATE

Premium quality ATE clutch master cylinder for Volkswagen Type 25 (T3) models. ATE were the original equipment supplier for many Volkswagen hydraulic braking and clutch systems, making this the ideal choice for owners seeking OEM quality, reliability and long service life.

The clutch master cylinder converts movement of the clutch pedal into hydraulic pressure, which is transmitted to the clutch slave cylinder to disengage the clutch. As the master cylinder wears, internal seals can fail causing fluid leaks, loss of hydraulic pressure, difficulty selecting gears, a sinking clutch pedal or complete clutch failure.

Replacing a worn master cylinder restores smooth clutch operation and ensures reliable hydraulic performance. This ATE unit is manufactured to OE specifications for precise fit and dependable operation.
