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 heat dissipation. This design helps reduce brake fade and maintain consistent braking under demanding conditions. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various environments.

Technical Specifications and Features

This rotor features a solid disc construction with a directional surface type that includes both drilled holes and slots. The drilled holes aid in venting gases and debris, while the slots help clean the brake pad surface for improved contact. The rotor measures 268 mm in outside diameter and 45.2 mm in height, with a nominal thickness of 12.1 mm and a discard thickness of 10 mm, ensuring precise fitment and performance. The zinc silver hat finish offers rust resistance, which is critical for maintaining rotor integrity over time. The rotor is designed with 5 bolt holes, each 14.1 mm in diameter, arranged on a 105 mm bolt circle diameter, matching the specifications required for compatible Buick and Chevrolet models.

Compatible Vehicles and Applications

• Buick Cruze and Cruze Limited
• Buick Encore
• Chevrolet Sonic
• Chevrolet Trax

This rotor is suitable for drivers seeking replacement parts that meet factory specifications for these vehicles, ensuring proper fit and reliable braking performance.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during extended braking
• Uneven brake pad wear due to poor rotor surface design
• Corrosion and rust buildup on rotor hats and surfaces
• Reduced braking efficiency from glazed or contaminated rotors
• Vibration or noise caused by warped or damaged rotors

Installation Notes and Tips

When installing the Dynamite Friction 631-45018R rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the bolt hole alignment matches the vehicle’s hub assembly, particularly the 5-lug pattern with a 105 mm bolt circle diameter. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Proper torque specifications should be followed to avoid rotor warping or uneven wear.
