FTE 8K1-721-401H Clutch Master Cylinder with Clutch Safety Switch

The FTE 8K1-721-401H Clutch Master Cylinder is a high-quality OE-supplier replacement unit engineered to restore proper hydraulic clutch operation. Mounted at the base of the clutch pedal, the master cylinder converts mechanical pedal input into hydraulic pressure, which is transmitted through the clutch line to the slave cylinder to engage and disengage the clutch pack.

Over time, the delicate internal rubber seals within the master cylinder are degraded by brake and hydraulic fluid, leading to fluid loss, a spongy or sinking clutch pedal, and inconsistent engagement. Replacing the master cylinder restores a firm, responsive pedal feel and smooth, precise shifting. This unit includes the integrated clutch safety switch.
