34216864900 BMW BRAKE DISC,

This BMW Brake Disc is a vital part of the vehicle's braking system, designed to handle high-performance driving in models like the 428i, 430i, and 330ix. It is specifically engineered for use in AWSD systems, ensuring optimal stopping power and control. The technical advantages of this brake disc include improved heat management, enhanced braking performance, and increased safety. Brake discs, or rotors, are metallic circular components integral to a vehicle’s braking system, mounted on the wheel hubs. They function as a friction surface for brake pads, converting kinetic energy into thermal energy via clamping force to decelerate or stop wheel rotation. Discs are typically constructed from gray cast iron, though carbon ceramic and composite materials are also utilized for performance applications. Key characteristics include diameter, thickness, venting style (solid, vented, drilled/slotted), and rotor hat offset. Variation exists between solid, vented, and cross-drilled/slotted designs, impacting heat dissipation and performance characteristics.
