Master Cylinder, clutch

The clutch master cylinder is the key component of a hydraulic clutch system, converting pedal pressure into hydraulic force and transmitting it to the slave cylinder. PartStall carries 4,656 clutch master cylinders for passenger cars, vans and light commercial vehicles from a wide range of manufacturers.

• Always verify fitment by make, model, engine type and production year — different gearbox versions of the same model may require different cylinders.
• Check the connector type, port count and hydraulic line fitting dimensions before ordering.
• Choose a part matching the OE reference number to ensure compatibility with the rest of the hydraulic system.
• After installation, the hydraulic system may need to be bled by a specialist — air in the system will prevent full clutch disengagement.

How do I know if the clutch master cylinder is faulty? Common signs include a sinking or spongy clutch pedal, lack of resistance, and clutch fluid leaking inside the cabin near the pedal.

Should the slave cylinder be replaced at the same time? It is not always mandatory, but since both components wear at a similar rate, it is worth inspecting the slave cylinder and replacing it if needed.

Can I tell if the problem is the clutch or the hydraulics? If the pedal feels soft or sinks to the floor but the clutch disc and pressure plate show no obvious wear, the fault may lie in the hydraulic circuit and should be checked with appropriate diagnostic tools.
