BMW Brake Caliper Carrier Mounting Bolt - Genuine BMW 34203414763

Product Information

A disc brake caliper bracket mounting bolt is a heavy-duty fastener that secures the brake caliper bracket to the vehicle’s steering knuckle or suspension assembly. This bolt plays a critical role in maintaining proper caliper alignment, ensuring consistent brake pad contact with the rotor for safe and effective braking. Because it endures high levels of heat, vibration, and stress, it must remain tight and in good condition to prevent brake system failures.

• Clunking or rattling noises from the brakes, often caused by loose or missing bolts.
• Uneven or poor braking performance, due to caliper misalignment.
• Excessive vibration during braking, resulting from loose or improperly torqued bolts.

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.
