Detailed Product Features and Specifications

This Dynamite Friction rotor is designed specifically for the braking systems of Ford Expedition and Lincoln Navigator vehicles. The rotor’s vented construction allows air to flow between the rotor faces, reducing heat buildup during braking. The drilled and slotted surface pattern is directional, which helps channel away water, dust, and brake pad debris, improving brake pad contact and reducing the risk of brake fade. The rotor’s hat is finished in zinc silver to resist corrosion, complemented by an overall rust-resistant coating to extend service life.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a silver zinc finish for enhanced durability and performance. This product line is designed to provide effective heat dissipation and maintain braking efficiency under demanding conditions, making it suitable for larger vehicles like the Ford Expedition and Lincoln Navigator.

Applications and Problem Solving

• Compatible with Ford Expedition and Lincoln Navigator models requiring 342 mm diameter rotors
• Addresses brake fade caused by excessive heat during towing or heavy braking
• Helps reduce brake dust accumulation on rotor surfaces
• Improves wet weather braking performance by channeling water away
• Prevents premature rotor corrosion with rust-resistant coatings

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. The 6-bolt pattern with 16 mm diameter holes and 135 mm bolt circle diameter must match the vehicle’s hub specifications. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and zinc silver hat finish contribute to long-term durability.
