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 feature both drilled holes and slots on the braking surface. This design helps to reduce brake fade by improving heat dissipation and allows for better water and gas evacuation during braking. The zinc silver hat finish and rust resistant coating contribute to longer rotor life, making it suitable for Chrysler Grand Caravan, Pacifica, and Voyager models requiring dependable braking components.

Product Description and Specifications

This disc brake rotor is engineered with a 320 mm outside diameter and a nominal thickness of 12 mm, ensuring compatibility with specified Chrysler vehicles. The rotor’s surface is both drilled and slotted, which enhances braking performance by allowing heat and gases to escape more efficiently. The directional brake surface is designed to optimize braking force and reduce uneven wear. The zinc silver hat finish and rust resistant coating protect against corrosion, extending the rotor’s service life. With five bolt holes measuring 14.6 mm in diameter and a bolt circle diameter of 127 mm, this rotor fits securely on the hub. The center hole diameter of 72.5 mm and a height of 35.4 mm complete the precise fitment specifications.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Chrysler Grand Caravan, Pacifica, and Voyager
• Improves braking performance by reducing heat buildup and brake fade
• Addresses rotor surface corrosion with rust resistant coating
• Helps eliminate brake noise and vibration caused by uneven rotor wear
• Suitable for vehicles experiencing reduced braking efficiency under heavy use

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify that the rotor thickness is within the nominal range of 12 mm and above the discard thickness of 10.4 mm. Use the correct torque specifications for the 5 lug bolts to avoid rotor warping. The directional surface requires installation in the correct orientation to maintain optimal braking performance. It is recommended to inspect brake pads and replace them if worn when installing new rotors.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for Chrysler Grand Caravan, Pacifica, and Voyager models. The rust resistant coating and zinc silver hat finish provide added durability against corrosion. While no specific warranty information is provided, the rotor is designed for consistent performance and longevity when installed and maintained properly.
