DF6689 TRW Brake Disc

TRW's DF6689 Brake Disc is used in applications where high-performance braking is required. It measures 118mm in height, 312mm in width, and 312mm in depth, providing a precise fit for vehicles with similar specifications. Dimensions are provided by the supplier and may include packaging dimensions. 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.
