Audi Brake Master Cylinder Reservoir - Genuine Audi 8W0611301

Product Information

A brake master cylinder reservoir stores brake fluid and feeds it to the front and rear brakes of a car. A failing brake master cylinder can cause a number of issues, including inconsistent brake performance, low fluid levels, and/or a low pedal.

• Brake pedal feels spongy: When the brake pedal feels soft or squishy, it could indicate air or moisture in the brake system. Low brake fluid levels, leaks, or improper bleeding can cause this.
• Brake fluid is contaminated: If the brake fluid is dark brown or black, it could be contaminated. This can happen when the rubber seals on the master cylinder wear out and break down.

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.
