Product Information

Audi Brake Hoses diagram for A4 Quattro, S4, RS4, A4

A brake vacuum hose is a reinforced rubber or plastic hose that connects the engine intake manifold (or a vacuum pump in some vehicles) to the brake booster. It supplies vacuum pressure that amplifies the driver’s braking force, allowing for easier and safer braking with less pedal effort.

• Hard brake pedal – little to no power assist, requiring extra force to stop.
• Hissing noise – air leak sound near the hose or brake booster.
• Increased stopping distance – reduced braking efficiency due to loss of vacuum assist.

About Genuine Audi

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

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