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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with enhanced surface features such as drilled holes and slots to improve brake pad bite and heat dissipation. This product line focuses on solid rotors with a directional surface design, providing consistent braking performance and resistance to rust with a zinc silver coating on the rotor hat. The 631-54194L rotor is a part of this line, tailored for specific fitment on select Ford, Mazda, and Mercury SUVs.

Technical Specifications and Features

This rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 11 mm, ensuring durability and safety margins. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape during braking. The directional surface type improves water and dust evacuation, maintaining effective braking in various conditions. The rotor hat is finished with a rust-resistant zinc silver coating to extend service life and reduce corrosion. It features five bolt holes with a diameter of 14.15 mm and a bolt circle diameter of 114.3 mm, matching the stud/lug hole pattern for secure installation.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Escape, Mazda Tribute, and Mercury Mariner
• Improves heat dissipation to reduce brake fade during heavy braking
• Slotted and drilled design helps maintain consistent braking performance in wet or dusty conditions
• Rust-resistant coating prevents premature corrosion and extends rotor life
• Directional surface design enhances braking efficiency and pad contact

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 11 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 114.3 mm bolt circle pattern. Proper torque specifications should be followed to avoid rotor warping. This rotor is designed for direct replacement on compatible Ford Escape, Mazda Tribute, and Mercury Mariner models.

Quality Assurance

Dynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Silver to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat enhances durability.
