Constructed from premium-quality materials with precision-machined internal components and durable hydraulic seals, the clutch master cylinder is engineered to withstand continuous pressure cycles, temperature fluctuations and daily use. It ensures consistent hydraulic force delivery, helping maintain smooth clutch engagement, precise gear changes and optimum driving comfort.
What This Product Does:
- Converts clutch pedal movement into hydraulic pressure.
- Transfers hydraulic force to the clutch slave cylinder.
- Enables smooth clutch disengagement and engagement.
- Supports accurate and effortless gear changes.
- Maintains consistent clutch pedal feel and response.
- Reduces clutch operating effort.
- Ensures reliable clutch system performance under all driving conditions.
- Contributes to overall drivetrain efficiency and drivability.
Symptoms Of Wear Or Failure:
- Soft, spongy or inconsistent clutch pedal feel.
- Clutch pedal sinking towards the floor.
- Difficulty selecting gears.
- Incomplete clutch disengagement.
- Clutch drag when changing gear.
- Hydraulic fluid leaks around the master cylinder.
- Low clutch fluid level.
- Increased clutch pedal effort.
- Grinding noises during gear engagement.
- Complete loss of clutch operation in severe cases.
Why Replacement Matters:
- The clutch master cylinder operates every time the clutch pedal is pressed and is continuously exposed to hydraulic pressure, fluid movement and temperature changes. Over time, internal seals can wear, pistons may deteriorate and corrosion can develop inside the cylinder bore, reducing hydraulic efficiency and clutch performance.
- A failing clutch master cylinder can make gear changes difficult, increase wear on the clutch and transmission components and significantly affect vehicle drivability. If left unresolved, complete hydraulic failure can occur, preventing the clutch from disengaging and potentially leaving the vehicle immobile.
- Replacing a worn or faulty clutch master cylinder restores proper hydraulic pressure, improves clutch pedal feel and ensures smooth gear engagement. An OE Match replacement provides factory-style fitment, reliable sealing performance and long-term durability, helping maintain the performance, comfort and reliability expected from your Porsche.

Molub-Alloy Paste White T – High Performance Assembly & Anti-Fretting Paste
Molub-Alloy Paste White T is a premium high-performance assembly paste designed to provide exceptional protection against fretting corrosion, stick-slip, wear, and seizure in demanding automotive, industrial, and workshop applications.
This white assembly paste applies cleanly and appears almost colourless when spread as a thin layer, making it ideal for precision assembly work where cleanliness and protection are equally important.
Formulated for universal assembly and thin-film lubrication applications, Molub-Alloy Paste White T helps simplify component assembly and future disassembly while protecting contact surfaces against corrosion, vibration-related wear, and moisture ingress.
Its advanced formulation provides excellent resistance to both hot and cold water while delivering long-lasting corrosion protection under harsh operating conditions.
Particularly effective in applications exposed to vibration and frictional movement, the paste helps prevent fretting corrosion and reduces stick-slip behaviour, making it ideal for hydraulic cylinders, open lubrication points, threaded assemblies, sliding surfaces, and mechanical components subject to oscillating movement.
The product also helps eliminate squeaking noises and improves smooth operation in moving assemblies exposed to high loads and thermal stress.
Suitable for temperatures ranging from -30°C to +250°C, Molub-Alloy Paste White T delivers reliable lubrication and anti-corrosion performance across a wide range of workshop, automotive, and engineering environments.
