Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on combining functional design with corrosion resistance. The rotor’s vented construction allows air to flow between the rotor faces, helping to dissipate heat during braking and reduce the risk of brake fade. The drilled and slotted surface pattern is directional, which aids in channeling away gases, dust, and water for improved contact between the brake pad and rotor.

The rotor’s nominal thickness is 26 mm, with a discard thickness of 24.5 mm, ensuring it meets safety standards for wear limits. The zinc silver hat finish and rust-resistant coating provide protection against corrosion, extending the rotor’s service life. With five bolt holes sized at 13.7 mm diameter and a bolt circle diameter of 114.3 mm, this rotor is designed to fit securely on compatible Ford Explorer and Mercury Mountaineer models.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford Explorer and Mercury Mountaineer
• Addresses brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions with slotted and drilled design
• Prevents rust and corrosion on braking surfaces
• Restores smooth and consistent brake pedal feel

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.5 mm before installation. Clean the hub surface and mounting area to prevent uneven rotor seating. Use proper torque specifications for the five lug bolts with 13.7 mm diameter holes. The directional surface requires correct orientation during installation to maintain optimal braking performance.
