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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade under demanding conditions, making it suitable for vehicles that require consistent braking performance. The zinc silver hat finish with rust-resistant coating extends rotor life by protecting against corrosion.

Detailed Product Description

This Dynamite Friction disc brake rotor features a solid construction with a 271 mm outside diameter and a nominal thickness of 12.5 mm, ensuring structural integrity and longevity. The drilled and slotted surface enhances water and gas evacuation from the braking surface, improving pad contact and braking efficiency. The directional design of the rotor surface optimizes airflow and cooling during operation. The zinc silver hat finish with rust-resistant coating helps maintain the rotor’s appearance and prevents premature rusting, which is critical for maintaining consistent braking performance over time.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves heat dissipation for consistent stopping power
• Minimizes water buildup on the rotor surface for wet weather braking
• Prevents rust and corrosion on the rotor hat for longer service life
• Compatible with vehicles requiring a 4-bolt rotor with 103 mm bolt circle diameter

Installation Notes and Tips

Ensure the rotor thickness is within the nominal 12.5 mm specification before installation. Replace the rotor if thickness is below the discard thickness of 10.5 mm. Confirm bolt hole pattern and center hole diameter (81 mm) match your vehicle’s hub assembly. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-67004L rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to extended rotor life. While no specific warranty information is provided, Dynamite Friction products are designed to comply with OEM quality requirements for reliable braking.
