Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors designed to improve heat dissipation and reduce brake fade. The drilled and slotted surface enhances water and debris evacuation, while the vented rotor design promotes airflow to maintain optimal operating temperatures. This rotor line is engineered to meet the demands of daily driving and moderate performance applications.

Technical Specifications and Features

This disc brake rotor features a vented design with a 276 mm outside diameter and an overall height of 45.8 mm, providing effective heat management during braking. The rotor surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and dust to escape. The directional surface type ensures proper rotation for maximum efficiency. The rotor’s nominal thickness is 26 mm, with a discard thickness of 24.4 mm, indicating when replacement is necessary. The zinc silver coating on the hat offers rust resistance, extending the rotor’s service life. It includes five bolt holes with a 13 mm diameter and a bolt circle diameter of 114.3 mm, matching the factory specifications for Dodge Caliber and Mitsubishi Lancer models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake discs on Dodge Caliber and Mitsubishi Lancer
• Improves braking consistency by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Resists rust and corrosion for longer service life in various weather conditions
• Maintains braking performance under wet or dusty conditions due to drilled and slotted design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify that the bolt hole pattern and diameter match the vehicle hub before installation. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system performance. Clean the rotor surface of any protective coatings or oils before installation to prevent brake noise and ensure proper pad bedding.

Quality Assurance

Dynamite Friction manufactures the 631-40024L rotor to meet or exceed OEM specifications for fit and function. The rust-resistant coating and vented design contribute to durability and consistent braking performance. While specific warranty details are not provided, this rotor is built to maintain reliable operation under normal driving conditions for Dodge Caliber and Mitsubishi Lancer vehicles.
