• Directional slotted and drilled surface for improved cooling and debris removal
• Rust-resistant zinc silver hat finish to reduce corrosion
• 6 bolt holes with a 13.2 mm diameter and 139.7 mm bolt circle diameter
• Outside diameter of 308 mm and height of 80.75 mm for precise fitment
• Center hole diameter of 93 mm compatible with specified Ford models

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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots in a directional pattern. This design aids in reducing brake fade by allowing gases and heat to escape more efficiently during braking. The zinc silver coating on the rotor hat provides additional rust resistance, extending the rotor's service life in various driving environments.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 24 mm and a discard thickness of 22 mm, ensuring clear guidelines for rotor replacement to maintain braking safety. The rotor’s surface is finished plain, while the hat is coated with a zinc silver rust-resistant finish. The rotor includes six bolt holes with a diameter of 13.2 mm arranged on a 139.7 mm bolt circle diameter, matching the Ford Bronco and Ranger bolt pattern. The directional slotted and drilled surface type improves braking performance by enhancing heat dissipation and reducing brake dust accumulation.

Applications and Problem Solving

• Compatible with Ford Bronco and Ranger models requiring 308 mm diameter rotors
• Helps reduce brake fade during heavy braking or towing
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup for cleaner braking surfaces
• Resists rust and corrosion for longer rotor life in wet or humid conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 6-bolt pattern and 139.7 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping or uneven wear.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust-resistant zinc silver coating on the rotor hat helps maintain structural integrity over time. While no specific warranty information is provided, adherence to discard thickness guidelines ensures safe and reliable braking performance.
