Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This product line is designed to reduce brake fade and maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life on Ford Explorer and Mercury Mountaineer models.

Product Specifications and Features

This vented disc brake rotor features a 305 mm outside diameter and a 54.3 mm overall height, ensuring compatibility with specified Ford and Mercury vehicles. The drilled and slotted surface type enhances water and gas evacuation from the braking surface, improving pad contact and braking response. The rotor’s directional design supports optimal airflow and heat management during braking. The zinc silver hat finish offers rust resistance, helping maintain structural integrity over time.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Explorer and Mercury Mountaineer
• Improves braking performance in wet or high-heat conditions due to drilled and slotted design
• Helps reduce brake fade during extended braking or towing
• Addresses rotor corrosion issues with rust-resistant coating
• Compatible with vehicles requiring a 5-lug, 114.4 mm bolt circle diameter rotor

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.5 mm before installation. Properly clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the 5-lug, 13.65 mm diameter holes and 114.4 mm bolt circle diameter for a secure fit. Use appropriate torque specifications for lug nuts to avoid rotor warping. Directional rotors should be installed following the indicated rotation direction for optimal performance.
