Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. This product line is designed to maintain braking efficiency under demanding conditions while providing corrosion resistance through a zinc silver coating on the rotor hat. The 631-46038R rotor exemplifies these features, making it suitable for performance-oriented applications on compatible Cadillac and Chevrolet vehicles.

Technical Description and Specifications

This disc brake rotor features a vented design that allows air to flow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface enhances water and debris evacuation, improving braking response in wet or dusty conditions. The rotor's nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring a clear service life indicator. The zinc silver coating on the hat provides rust resistance, extending the rotor's durability. With 5 bolt holes sized at 16 mm diameter and a 120 mm bolt circle diameter, this rotor fits securely on the hub. The directional surface design requires correct orientation during installation to maximize performance.

Compatible Vehicles and Common Applications

• Replacement rotor for Cadillac ATS, CTS, CT6 models requiring vented, drilled, and slotted rotors
• Suitable for Chevrolet Camaro models needing enhanced braking performance
• Addresses issues such as brake fade under heavy use
• Helps reduce rotor warping caused by excessive heat
• Improves braking consistency in wet or contaminated conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern (5 holes, 16 mm diameter, 120 mm bolt circle) matches the vehicle hub. Clean the rotor surface before installation to remove any protective coatings or residues. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 30 mm and is above the discard thickness of 27 mm.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-46038R rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating on the rotor hat helps prevent corrosion, contributing to longer service life. Warranty details are provided by the manufacturer and should be consulted for specific coverage information.
