Detailed Product Description

The Raybestos 680977 disc brake rotor is part of the Specialty - Truck; Coated Rotor line, designed specifically for truck applications such as the Ford F-150. This rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade under heavy loads or extended use. The coated surface provides a protective layer against rust and corrosion, which is critical for maintaining rotor integrity and performance over time.

With a nominal thickness of 0.984 inches (25.000 mm) and a discard thickness of 0.906 inches (23.000 mm), this rotor ensures a balance between durability and serviceability. The drum-in-hat configuration integrates a drum brake surface within the rotor, supporting parking brake functionality common in truck brake systems. The rotor includes 7 mounting bolt holes arranged on a 5.906 inch (150.000 mm) bolt circle diameter, matching the Ford F-150 specifications for secure installation.

Applications and Problem Solving
