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 combine drilled holes and slots to improve braking efficiency and rotor longevity. The silver zinc coating on the rotor hat provides corrosion resistance, while the vented rotor design helps maintain optimal operating temperatures. This product line is tailored for drivers seeking a balance between performance and durability on specific Cadillac models.

Technical Specifications and Features

This disc brake rotor measures 304 mm in outside diameter and 128 mm in overall height, with a center hole diameter of 77.8 mm. It includes five bolt holes sized 1/2-20, arranged on a 127 mm bolt circle diameter, matching the stud/lug hole circle diameter for secure fitment. The rotor’s nominal thickness is 31.67 mm, with a discard thickness of 30.86 mm, ensuring clear service limits for safety. The rotor surface is directional with both slots and drilled holes, designed to reduce brake fade by improving heat dissipation and removing gas and debris from the pad surface. The zinc silver hat finish adds rust resistance to critical mounting areas.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Cadillac Commercial Chassis, DeVille, and Fleetwood
• Improves braking performance by reducing heat buildup and brake fade
• Helps prevent rust and corrosion on rotor hats for longer service life
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Maintains consistent braking under heavy load or frequent stop conditions

Installation Notes and Tips

Ensure the rotor is installed on compatible Cadillac models as specified. Verify bolt hole alignment with the 1/2-20 bolt size and 127 mm bolt circle diameter. Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction to maintain performance benefits.
