Product Information

BMW Brake Boosters diagram for M3, M4

A power brake booster vacuum pump is a component that provides the necessary vacuum pressure for the brake booster, ensuring consistent braking assistance. This is especially important in vehicles with turbocharged, supercharged, or diesel engines, where natural engine vacuum may be insufficient. By supplying stable vacuum pressure, the pump allows the brake booster to reduce pedal effort, improving braking efficiency and driver control.

• Hard or stiff brake pedal, requiring more effort to stop the vehicle.
• Longer stopping distances, due to reduced brake assist.
• Unusual noises (whining or clicking) from the pump, often signaling wear or failure.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

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