Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve water and gas evacuation during braking. This design helps maintain consistent brake pad contact and reduces brake fade under demanding conditions. The zinc silver hat finish and rust-resistant coating extend rotor life by protecting against corrosion, making it suitable for Cadillac CTS and STS models requiring reliable braking components.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking performance during extended use. The rotor’s nominal thickness is 26 mm, with a discard thickness of 24 mm, ensuring safe replacement intervals. The rotor measures 320 mm in outside diameter and 48.1 mm in overall height, fitting precisely on compatible Cadillac CTS and STS vehicles. The five bolt holes, each 13 mm in diameter, are arranged on a 115 mm bolt circle diameter, matching factory specifications. The directional slotted and drilled surface improves braking response by channeling away debris and heat.

Applications and Problem Solving

• Restores braking performance on Cadillac CTS and STS models with worn or damaged rotors
• Reduces brake fade during high-temperature braking conditions
• Improves water and gas evacuation for consistent brake pad contact
• Prevents rust and corrosion with zinc silver hat finish and protective coating
• Maintains proper fitment and alignment with factory bolt pattern and dimensions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the five 13 mm bolt holes arranged on the 115 mm bolt circle diameter. Verify the directional rotor is installed with the correct rotation direction for optimal performance. It is recommended to replace brake pads when installing new rotors to ensure even wear and braking efficiency.

Quality Assurance

Dynamite Friction manufactures the 631-46020R rotor to meet OEM standards for fitment and performance on Cadillac CTS and STS models. The rust-resistant coating and zinc silver hat finish provide durability against corrosion. While no specific warranty information is provided, the rotor is designed to comply with industry quality and safety requirements for disc brake rotors.
