Detailed Product Description
The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed specifically for Ford Bronco and F-150 trucks, ensuring precise fitment and reliable braking performance. The rotor’s vented construction allows air to flow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade. The directional slotted and drilled surface improves pad bite and helps evacuate gases, dust, and water from the braking surface, which contributes to consistent stopping power in various driving conditions.
Constructed with a plain disc finish and a zinc silver rust-resistant coating on the hat, this rotor offers durability and corrosion resistance, extending the service life of the braking system. The rotor measures 298 mm in outside diameter with a 69 mm height, and it features five bolt holes with a 16.4 mm diameter arranged on a 139.7 mm bolt circle diameter, matching the factory specifications for the intended Ford models.
