The clutch slave cylinder receives hydraulic pressure from the clutch master cylinder and pushes the clutch fork to disengage the clutch. A leaking slave cylinder causes a soft pedal, difficulty changing gears, and eventual clutch failure. External slave cylinders are bolted to the gearbox; concentric types sit inside the bellhousing.
Slave cylinder failure symptoms
Slave cylinder failures are usually caused by seal degradation. External cylinders leak visibly; concentric types leak into the bellhousing.
- Soft or spongy clutch pedal
- Clutch fluid leak visible on the outside of the gearbox (external type)
- Clutch does not fully disengage — difficulty selecting gears
- Clutch fluid level drops in the reservoir
- Clutch pedal goes to the floor with little resistance
Replacement advice
External slave cylinders are accessible without removing the gearbox. Concentric slave cylinders require gearbox removal and are usually replaced with the clutch.
- External: bolt-on replacement without gearbox removal, bleed the system after fitting
- Concentric: requires gearbox removal — replace with the clutch kit to avoid double labour
- Always bleed the hydraulic system after fitting a new cylinder
- Check the master cylinder condition at the same time — often both fail at similar mileages

Dažnai užduodami klausimai
What is a concentric slave cylinder?
A concentric slave cylinder (CSC) fits around the gearbox input shaft inside the bellhousing. It eliminates the need for a clutch fork but requires gearbox removal for replacement.
Should I replace the slave cylinder with the clutch?
For concentric types, absolutely — the gearbox is already out. For external types, it is good practice if the cylinder is old or showing signs of seepage.
How do I know if the master or slave cylinder is leaking?
The slave cylinder leak is visible on the gearbox. The master cylinder leak is visible at the pedal box or firewall. If no external leak is visible, the master cylinder may be bypassing internally.
Can air in the clutch hydraulic system cause problems?
Yes. Air is compressible, so even a small air bubble in the system causes a spongy pedal and incomplete clutch disengagement.
How much does clutch slave cylinder replacement cost?
The price of a clutch slave cylinder depends on your exact vehicle and the brand you choose. Enter your registration above to see parts confirmed to fit, then compare prices from the brands we stock on this page. Free UK delivery on orders over £99.
