Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to aid in heat dissipation and debris removal. This design helps maintain consistent braking performance under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This part number 631-54007R is a representative model within this line, tailored for specific Ford and Mercury vehicles.

Technical Specifications and Features

This rotor features a vented design that improves airflow to reduce heat buildup during braking. The drilled and slotted surface enhances water and gas evacuation, which helps maintain pad contact and reduces brake fade. The rotor's nominal thickness is 24 mm, with a discard thickness of 22.4 mm, ensuring clear service limits for safety. The 4-bolt hole pattern with a 108 mm bolt circle diameter matches the specified Ford Escort, Mercury Lynx, and related models. The zinc silver hat finish offers rust resistance, while the plain disc finish supports consistent braking friction.

Compatible Vehicles and Applications

• Ford Escort (various years)
• Mercury Lynx
• Ford LN7
• Ford Tempo
• Mercury Topaz

This rotor is designed to replace worn or damaged rotors on these vehicles, restoring braking performance and safety.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven braking due to rotor warping or scoring
• Corrosion and rust on rotor surfaces
• Reduced braking efficiency from worn or glazed rotors
• Brake noise and vibration related to rotor surface condition

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.4 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants. Verify the 4-bolt hole pattern and 108 mm bolt circle diameter match the vehicle hub. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal performance.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit and function. The zinc silver coating provides rust resistance to extend rotor life. While specific warranty details are not provided, Dynamite Friction products typically undergo rigorous quality control to ensure durability and performance on compatible Ford and Mercury models.
