Land Rover Part Number: STC500031 - Clutch Master Cylinder
STC500031 is a clutch master cylinder that supplies hydraulic pressure to the clutch release system on manual-transmission Discovery 4 models fitted with the ZF S6-53 6-speed manual transmission. The unit converts pedal input into hydraulic pressure via a piston and reservoir assembly and transmits that pressure through the hydraulic line to the clutch slave cylinder or concentric slave to disengage the clutch; internal seals maintain pressure and the piston returns under spring force when pedal pressure is released. Regular inspection for fluid contamination, external leaks and seal wear is important to maintain consistent clutch operation, and replacement restores correct hydraulic pressure and pedal feel where internal wear or leakage has developed.
