Audi Brake Hydraulic Line - Genuine VW Audi 8E0611721A

Product Information

A brake hydraulic line is a high-pressure tube or hose in a vehicle’s braking system that carries brake fluid from the master cylinder to the brake calipers or wheel cylinders. It’s a critical part of a hydraulic braking system, where brake fluid pressure is used to apply the brakes.

Hydraulic lines can be made of steel tubing (hard lines) or reinforced flexible rubber/stainless braided hoses (flex lines, usually near the wheels to allow movement).

• Spongy or Soft Brake Pedal: Air or fluid leaks in the line reduce pressure, making the pedal feel soft or sink lower than normal.
• Reduced Braking Power / Increased Stopping Distance: A leak lowers fluid pressure, so brakes won’t engage as strongly.
• Brake Fluid Leaks: Visible puddles or drips under the car, usually near a wheel or along the undercarriage. Brake fluid is typically clear to light brown and slippery.

About Genuine VW Audi

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 VAG to build your car are available as replacement parts under the “Genuine VAG” brand. Manufactured under the direction of VAG, expect excellent quality and a premium price since these parts are available exclusively through the VAG Dealership network.

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

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct 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.
