About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced surface features such as drilled holes and slots. These design elements help to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life. This line is tailored for drivers seeking reliable braking components compatible with specific Buick and Chevrolet models.

Technical Details and Specifications

This solid disc brake rotor measures 278 mm in outside diameter and 50.7 mm in overall height, ensuring compatibility with the specified vehicle models. The rotor features a plain disc finish combined with a zinc silver hat finish that resists corrosion. The drilled and slotted surface type is directional, designed to optimize braking performance under various driving conditions. The rotor includes five bolt holes and lug holes, each with a diameter of 14.2 mm, arranged on a 114.3 mm bolt circle diameter, matching the factory specifications for Buick Allure, LaCrosse, Chevrolet Impala, and Monte Carlo.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves heat dissipation to reduce brake fade during heavy braking
• Addresses rust and corrosion issues on rotor hats and surfaces
• Enhances braking response for vehicles experiencing reduced stopping power
• Suitable for restoring factory-level braking performance on compatible Buick and Chevrolet models

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9 mm before installation. Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify bolt hole alignment with the vehicle hub using the 114.3 mm bolt circle diameter and 14.2 mm bolt hole diameter. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-45011R rotor to meet or exceed OEM standards for fit and function. The rust-resistant coating and precision machining contribute to durability and consistent braking performance. Warranty details should be confirmed with the product documentation or supplier, as coverage may vary.
