1K0721388AF Audi master cyl

This thing basically takes the force from your foot pressing the clutch pedal and turns it into hydraulic pressure. It’s a pump, really – a pretty simple one, but vital. It stores brake fluid and, when you push the pedal, pushes that fluid down the line. It also has reservoirs to keep the system full and maintain that pressure even when you aren’t actively pushing the pedal. This is part of your clutch hydraulic system. When you push down on the clutch pedal, the master cylinder pushes fluid through the line to the slave cylinder, which actually disengages the clutch. Without it working correctly, you won’t be able to smoothly shift gears. It's a key piece in getting power from the engine to the wheels. If this starts to go bad, you'll notice it. You might have a spongy or soft clutch pedal, meaning it feels like it’s giving way too easily. Sometimes it’ll feel hard to push, or you might have trouble getting into gear at all. Basically, it’s responsible for cleanly disengaging the engine from the transmission so you can shift. If it fails completely, you could be stuck in gear, or unable to get into gear. It acts like a shield, protecting the rest of the system, so if it goes bad, other components can suffer. We carry a good selection of these at Fixparts Online, and honestly, replacing it before it fails completely is a lot easier than dealing with a breakdown on the road. Long-term solution: Master Cylinder (MPN 1K0721388AF) comes with a 12-month warranty!
