BMW Clutch Slave Cylinder - Genuine BMW 21521159045

Product Information

A clutch slave cylinder is a hydraulic component in a manual transmission system that assists in engaging and disengaging the clutch. When the clutch pedal is pressed, hydraulic fluid is forced into the slave cylinder, which then moves the clutch release fork, allowing the driver to shift gears smoothly. It works in tandem with the clutch master cylinder to transfer force from the pedal to the clutch assembly.

• Difficulty Shifting Gears: If the slave cylinder fails, it may not fully disengage the clutch, making it difficult to shift gears smoothly, especially into first or reverse
• Soft or Spongy Clutch Pedal: A common symptom is a spongy or soft feel when pressing the clutch pedal, as the slave cylinder fails to build adequate hydraulic pressure
• Clutch Pedal Stuck to the Floor: In severe cases, the clutch pedal may stick to the floor or be slow to return, preventing proper clutch engagement and making it hard to drive.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand.

Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
