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 brake pad bite and reduce heat buildup. The silver zinc coating on the hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of drivers requiring consistent braking performance under varied driving conditions, specifically tailored for vehicles like the Cadillac SRX and Saab 9-4X.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases and debris from the brake pad interface, reducing brake fade and improving wet weather braking. The rotor has a nominal thickness of 23 mm and a discard thickness of 21.5 mm, ensuring it meets safety standards for wear limits. The overall diameter measures 315 mm with a height of 48 mm, fitting precisely on compatible vehicles. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time. The rotor includes six bolt holes with a diameter of 16.06 mm and a bolt circle diameter of 120 mm, matching the stud/lug hole pattern of the specified vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Cadillac SRX and Saab 9-4X
• Improves heat dissipation to reduce brake fade during heavy braking
• Slotted and drilled surface helps maintain braking performance in wet conditions
• Rust-resistant coating prevents corrosion-related rotor damage
• Directional design optimizes braking efficiency and pad contact

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the vehicle manufacturer. Verify that the rotor thickness is within the nominal and discard limits before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Use proper torque specifications for the six lug bolts to secure the rotor firmly. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system performance.

Quality Assurance

The Dynamite Friction 631-46045L rotor is manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, Dynamite Friction products typically adhere to industry standards for quality and reliability.
