Land Rover Part Number: STC100390 - Clutch Master Cylinder
STC100390 is a clutch master cylinder used on manual 4.0 EFi V8 Discovery 2 vehicles built from early 1999 to 2002. Fitted to the clutch hydraulic circuit, its piston pressurises hydraulic fluid when the clutch pedal is depressed and sends pressure through the connected pipework to the clutch slave cylinder or concentric slave so the clutch can disengage cleanly. Common service issues include fluid contamination, internal seal wear and external leaks; these faults reduce hydraulic pressure and affect pedal feel. Replacement should match the specified part number and the vehicle's VIN range to ensure the correct bore size and pipe connections for the Discovery 2 4.0 EFi V8 application.

Frequently Asked Questions
The STC100390 clutch master cylinder converts clutch pedal movement into hydraulic pressure that operates the clutch on manual 4.0 EFi V8 Discovery 2 models. When the pedal is depressed a piston pressurises fluid and sends it to the slave cylinder or concentric slave to disengage the clutch for gear changes. Common failure modes are internal seal wear, fluid contamination and external leaks, which lead to poor pedal feel or loss of hydraulic pressure; inspect the hydraulic system if these symptoms appear.
