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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine 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 black coating on the rotor hat provides additional rust resistance, extending the rotor's service life. This product line is tailored for drivers seeking a balance between performance and durability in their braking components.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal channels to allow air flow and reduce heat buildup during braking. The rotor's surface is both drilled and slotted, arranged directionally to optimize braking efficiency. The nominal thickness is 30 mm, with a discard thickness of 27 mm, indicating when the rotor should be replaced. The rotor features a plain disc finish and a zinc black finish on the hat for corrosion resistance. It includes five bolt holes and stud/lug holes, each with a diameter of 16.2 mm, spaced on a 120 mm bolt circle diameter. The center hole diameter measures 67.5 mm, and the overall height is 51.1 mm, with an outside diameter of 345 mm.

Applications and Problem Solving

  • Replacement rotor for worn or warped brake rotors on Buick Regal and Cadillac XTS
  • Improves heat dissipation to reduce brake fade during heavy braking
  • Slotted and drilled surface helps remove brake dust and water for consistent braking
  • Rust-resistant coating prevents corrosion in humid or wet environments
  • Maintains proper braking performance and safety on vented rotor-equipped vehicles

Installation Notes and Tips

Ensure the rotor is compatible with your specific Buick Regal or Cadillac XTS model year before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the 5 lug bolts (16.2 mm diameter) to secure the rotor. Since this rotor is directional, verify the correct orientation during installation to maintain optimal braking performance. Inspect brake pads for wear and replace if necessary to complement the new rotor.

Quality Assurance

Dynamite Friction manufactures the 633-45019L rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc black coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, this rotor is designed for reliable performance and longevity when installed and maintained properly.
