A brake bleeder screw is a small valve located on each brake caliper or wheel cylinder that allows air and old fluid to be purged from the brake system during servicing. By opening the screw, technicians can bleed trapped air, ensuring the hydraulic system is filled only with brake fluid for proper pressure and braking performance. A functioning bleeder screw is essential for safe, consistent braking.

• Difficulty bleeding brakes, due to a clogged or seized screw.
• Brake fluid leaks around the screw threads.
• Soft or spongy brake pedal, if air remains trapped because of a faulty bleeder screw.

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.

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.
