BMW Clutch Slave Cylinder - Febi Bilstein 21526775924

Product Information

This aftermarket clutch slave cylinder by Febi-Bilstein is responsible for controlling the operation of the shift fork inside the transmission bellhousing — a critical component in BMW's clutch hydraulic system. It works in tandem with the clutch master cylinder to convert pedal force into hydraulic pressure, allowing smooth engagement and disengagement of the clutch.

On higher mileage BMWs, slave cylinders are a common failure point. If your clutch pedal drops to the floor, doesn’t return, or there’s visible brake fluid leaking under the transmission, the slave cylinder is likely at fault and should be replaced. It is also recommended to replace the clutch master cylinder at the same time to restore full system function.

Common symptoms of clutch slave cylinder failure include:

• Difficulty shifting gears: Poor disengagement can make shifting into first or reverse especially hard.
• Soft or spongy clutch pedal: Caused by internal leakage or air in the system due to failing seals.
• Clutch pedal stuck to the floor: Severe hydraulic failure can prevent proper clutch engagement and safe driving.

Febi-Bilstein provides reliable aftermarket solutions engineered to meet or exceed OE performance and fitment standards.
