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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced heat management and corrosion resistance. Featuring a vented design combined with a directional, slotted and drilled surface, these rotors help maintain consistent braking performance under demanding conditions. The zinc silver coating on the rotor hat provides additional protection against rust, extending the rotor's service life.

Detailed Product Description

This disc brake rotor is constructed with a vented design to improve airflow and reduce heat buildup during braking. The directional surface pattern, featuring both drilled holes and slots, aids in gas and debris evacuation, which helps maintain pad contact and reduces brake fade. The rotor's nominal thickness is 24.1 mm, with a discard thickness of 22.7 mm, ensuring a clear service limit for safety. The rotor's hat is finished with a rust-resistant zinc silver coating to protect against corrosion, especially important for off-road capable Jeep models like the Wrangler and Grand Cherokee. With 5 bolt holes sized at 15.6 mm diameter and a bolt circle diameter of 114.3 mm, this rotor fits securely on compatible Jeep hubs.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Cherokee and Grand Cherokee
• Improves braking performance in off-road conditions for Jeep Wrangler and TJ
• Reduces brake fade caused by heat buildup during towing or heavy braking
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances braking consistency with directional drilled and slotted surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.7 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the 5 lug bolts with 15.6 mm diameter to avoid warping. This rotor is directional; verify the correct orientation during installation to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function on Jeep models including Cherokee, Comanche, Grand Cherokee, Grand Wagoneer, TJ, Wagoneer, and Wrangler. The rust-resistant zinc silver finish and vented design contribute to durability and consistent braking. Warranty information is available through the manufacturer and should be confirmed at the time of purchase.
