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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. The black zinc coating on the hat enhances corrosion resistance, extending rotor life. This product line is designed to meet the specific braking needs of vehicles like the Jeep Cherokee, Comanche, and Wagoneer, providing a balance of performance and durability.

Detailed Product Description

This disc brake rotor is vented to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface helps evacuate gases, dust, and water, improving braking response and reducing the risk of brake fade. The rotor’s directional design ensures optimal contact with brake pads, enhancing stopping power. With a nominal thickness of 21.6 mm and a discard thickness of 20.7 mm, the rotor maintains structural integrity throughout its service life. The zinc black hat finish and rust-resistant coating protect against corrosion, which is especially beneficial for vehicles exposed to harsh weather or off-road conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Cherokee, Comanche, and Wagoneer
• Improves heat dissipation to reduce brake fade during heavy braking
• Enhances braking performance in wet or dusty conditions with drilled and slotted design
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains proper rotor thickness to ensure safe braking operation

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern matches your vehicle’s hub (5 bolts, 1/2-20 diameter, 114.3 mm bolt circle). Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 20.7 mm.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for Jeep Cherokee, Comanche, and Wagoneer models. The rust-resistant coating and zinc black hat finish contribute to extended rotor life. While no specific warranty information is provided, the product is designed for reliable, consistent braking performance under normal operating conditions.
