Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking performance. This design helps reduce brake fade by allowing gases and debris to escape while maintaining consistent pad contact. The zinc silver hat finish provides corrosion resistance, complementing the rust resistant coating on the rotor surface. This product line is tailored for commercial and fleet vehicles requiring dependable stopping power and durability.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 18 mm and a discard thickness of 15 mm, ensuring a long service life before replacement is necessary. The rotor’s overall height is 22 mm, matching the height of the hat section. The 6-bolt hole configuration with a 13.8 mm diameter and 148 mm bolt circle diameter ensures compatibility with specified Ford Transit models. The directional slotted and drilled surface improves water and dust evacuation, enhancing braking efficiency in various driving conditions.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford E-Transit and Transit series
• Improves heat dissipation to reduce brake fade during heavy-duty or frequent braking
• Helps maintain consistent braking performance in wet or dusty environments
• Addresses rotor corrosion issues with rust resistant coating and zinc silver hat finish
• Supports fleet maintenance with durable, long-lasting rotor design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 15 mm before installation. Clean the hub surface and verify bolt hole alignment with the 6-bolt pattern and 148 mm bolt circle diameter. Use proper torque specifications for the 13.8 mm diameter lug holes to secure the rotor. The directional surface requires correct orientation to maintain optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Ford E-Transit and Transit models. The rust resistant coating and zinc silver hat finish contribute to corrosion protection and extended rotor life. Warranty details are available through the manufacturer or authorized distributors.
