BMW Brake Drum - Genuine BMW 34211101742

Product Information

A brake drum is a cylindrical braking component used in drum brake systems, typically found on the rear wheels of many vehicles. When the brake pedal is pressed, brake shoes press outward against the inside surface of the drum, creating friction that slows or stops the wheel. Made of durable cast iron or steel, brake drums must withstand high heat and stress while providing consistent braking performance.

• Reduced braking efficiency, often requiring longer stopping distances.
• Pulsation or vibration when braking, caused by an out-of-round or warped drum.
• Grinding or scraping noises, indicating excessive wear or damage to the drum surface.

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.
