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 provide enhanced heat management and improved braking response. The drilled and slotted surface design helps to reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better airflow. The zinc silver hat finish adds corrosion resistance, extending the rotor's service life on Jeep models such as the Cherokee and Wrangler.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 22.2 mm and a discard thickness of 20.7 mm, ensuring it meets safety standards for replacement. The rotor's 280 mm outside diameter and 76.7 mm height are designed to match factory specifications for the listed Jeep models. The rotor includes five bolt holes with a diameter of 15.7 mm and a bolt circle diameter of 114.3 mm, compatible with the stud/lug hole pattern on these vehicles. The directional surface type, combining slotted and drilled patterns, improves braking efficiency by maintaining pad contact and reducing heat buildup during heavy braking.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jeep Cherokee, Comanche, Wagoneer, and Wrangler
• Improves braking performance under high heat conditions
• Reduces brake fade during extended downhill or towing scenarios
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad bite and reduces noise with slotted and drilled design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (20.7 mm) before installation
• Clean rotor surface to remove any protective coating before mounting
• Verify bolt hole alignment with vehicle hub using the 114.3 mm bolt circle diameter
• Use proper torque specifications for lug nuts to avoid rotor warping
• Inspect brake pads for wear and replace if necessary to maximize rotor performance
