VW Clutch Master Cylinder - Genuine VW 5Q0721388H

Product Information

The clutch master cylinder is a critical component of a hydraulic clutch system in manual transmission vehicles. It is responsible for converting the mechanical force applied by the driver’s foot on the clutch pedal into hydraulic pressure, which then engages or disengages the clutch. The master cylinder is connected to the clutch pedal and the slave cylinder via a hydraulic line.

• Difficulty Engaging or Disengaging the Clutch: A failing master cylinder can make it hard to press the clutch pedal down or may result in the clutch not fully disengaging, causing difficulty in shifting gears
• Spongy or Soft Clutch Pedal: If there are air bubbles in the hydraulic system due to a leak or failure, the clutch pedal may feel spongy or soft, requiring more effort to engage the clutch
• Fluid Leaks: Visible leaks around the clutch master cylinder or along the hydraulic line can indicate a failure. This may be noticed as fluid pooling under the vehicle or around the clutch pedal area

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW 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 VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
