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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps maintain consistent braking by allowing gases, dust, and water to escape, reducing brake fade and improving pad bite. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Description and Specifications

This disc brake rotor is vented, which means it has internal vanes between the two braking surfaces to promote airflow and heat dissipation during braking. The rotor's nominal thickness is 20 mm, with a discard thickness of 18 mm, indicating when replacement is necessary. The rotor surface is directional, meaning it is designed to rotate in a specific direction to optimize slot and drill performance. The rotor features four bolt holes with a 100 mm bolt circle diameter, compatible with Toyota Echo and MR2 Spyder models. The zinc silver finish on the rotor hat provides rust resistance, while the plain disc finish maintains a clean appearance.

Applications and Problem Solving

• Compatible with Toyota Echo and MR2 Spyder models requiring vented, drilled, and slotted rotors
• Helps reduce brake fade during aggressive or repeated braking
• Improves water and debris evacuation from the rotor surface for consistent braking in wet conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Maintains braking performance by preventing pad glazing and uneven wear

Installation Notes and Tips

Ensure the rotor is installed with the correct directional orientation as indicated by the slot and drill pattern. Verify that the rotor thickness is within the nominal range before installation and replace if below discard thickness. Clean the rotor surface of any protective coatings or oils before mounting to ensure proper pad contact. Use the correct torque specifications for the four bolt holes with a 100 mm bolt circle diameter to secure the rotor properly.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fitment and performance. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, adherence to installation guidelines and regular inspection of rotor thickness will ensure reliable braking performance.
