• Vented rotor design for improved cooling
• Directional slotted and drilled surface for debris removal and heat management
• Zinc silver hat finish with rust-resistant coating
• 5 bolt holes with 1/2-20 diameter and 114.3 mm bolt circle diameter
• Overall diameter of 276 mm and height of 63.3 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is constructed with a plain disc finish and a zinc silver hat finish that includes a rust-resistant coating to extend rotor life. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps channel away brake dust, water, and gases, which can improve brake pad contact and reduce fade. The rotor features five bolt holes with a 1/2-20 diameter and a bolt circle diameter of 114.3 mm, matching the factory specifications for Ford Explorer and Mazda Navajo models. The overall diameter of 276 mm and height of 63.3 mm ensure proper fitment and compatibility.

About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver product line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant silver zinc finish. This line is designed to provide enhanced braking performance through improved heat dissipation and surface cleaning, while the rust-resistant coating helps maintain rotor integrity over time. The silver zinc hat finish also offers additional protection against environmental elements.

Applications and Problem Solving

• Compatible with Ford Explorer and Mazda Navajo models requiring 276 mm diameter rotors
• Addresses brake fade caused by excessive heat during heavy braking
• Helps reduce brake dust buildup on rotor surfaces
• Improves wet weather braking by channeling water away from the rotor surface
• Prevents rust and corrosion on the rotor hat and mounting surfaces

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20.6 mm before installation. The rotor is designed for vehicles with a 5-lug, 114.3 mm bolt circle pattern and 1/2-20 bolt hole diameter. Proper torque specifications should be followed when mounting the rotor to avoid warping. It is recommended to inspect brake pads and calipers during installation to ensure optimal braking performance.
