Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is a vented disc brake rotor designed to meet the braking demands of Ford and Mercury full-size sedans. Its drilled and slotted surface helps to dissipate heat and gases generated during braking, reducing the risk of brake fade and maintaining consistent stopping power. The rotor features a zinc silver hat finish that provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 19 mm and a discard thickness of 18 mm, this rotor ensures durability and safety throughout its lifespan.

The rotor's directional surface pattern is engineered to optimize braking performance by channeling water and debris away from the contact surface. The 5-bolt hole configuration with a 14.3 mm diameter and 114.3 mm bolt circle diameter matches the factory specifications for the Ford Crown Victoria, Mercury Grand Marquis, and Marauder models. The vented design further enhances cooling by allowing air to flow between the rotor surfaces, which helps maintain brake efficiency during extended use.

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

The DFC Brake Rotor - Drilled and Slotted - Silver product line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking performance under demanding conditions. This line is designed to provide enhanced heat dissipation and gas evacuation compared to standard rotors, making it suitable for vehicles requiring reliable braking in both everyday driving and more strenuous situations. The silver zinc coating on the rotor hat adds a layer of rust resistance, contributing to longer rotor life and consistent performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Crown Victoria, Mercury Grand Marquis, and Marauder
• Improves braking response and reduces brake fade during heavy use
• Helps prevent rotor cracking and surface glazing caused by excessive heat
• Addresses corrosion issues with rust-resistant zinc silver coating
• Restores proper braking performance for vehicles with uneven or noisy braking

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness of 18 mm before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Use proper torque specifications for the 5 lug bolts with 14.3 mm diameter
• Check compatibility with vehicle make and model before installation
• Inspect brake pads for wear and replace if necessary to maximize rotor performance
