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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide reliable braking performance with enhanced heat dissipation and surface durability. The drilled and slotted design helps maintain consistent braking under demanding conditions by allowing gases and debris to escape, while the zinc silver coating on the rotor hat offers corrosion resistance. This product line focuses on combining functional surface treatments with vented rotor construction to support longer rotor life and stable braking for compatible vehicles like the Mitsubishi Diamante.

Product Features and Specifications

This disc brake rotor is vented to improve airflow and reduce heat buildup during braking, which helps prevent brake fade. The directional slotted and drilled surface is engineered to channel away dust, water, and gases generated during braking, improving pad contact and overall stopping power. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring clear service limits for safety. The zinc silver finish on the rotor hat provides rust resistance, extending the rotor’s service life in various driving conditions.

Common Applications and Problem Solving

• Replacement rotor for worn or warped Mitsubishi Diamante brake rotors
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Resists rust and corrosion for longer rotor durability
• Maintains consistent braking performance in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 18.4 mm. Clean the rotor surface and hub mounting area to remove any debris or rust before mounting. Use proper torque specifications for the 5 bolt holes with a 114.3 mm bolt circle diameter to secure the rotor. This rotor is directional, so verify the correct orientation during installation to maintain optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-72027L rotor to meet OEM specifications for the Mitsubishi Diamante. The rust resistant coating and vented design contribute to the rotor’s durability and consistent braking performance. Warranty details are provided by the manufacturer and should be consulted for coverage specifics.
