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 on the braking surface to improve water and gas evacuation during braking. This design helps maintain consistent brake pad contact and reduces the risk of brake fade. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving conditions.

Technical Specifications and Features

This rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking performance under heavy use. The directional surface pattern ensures that the drilled holes and slots are oriented to optimize debris removal and cooling. With a nominal thickness of 24 mm and a discard thickness of 21 mm, this rotor meets the necessary safety standards for replacement parts. The rotor's bolt hole diameter and stud/lug hole diameter are both 14.2 mm, with four holes arranged on a 100 mm bolt circle diameter, ensuring proper fitment on compatible Pontiac LeMans models.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Pontiac LeMans
• Improves braking performance by reducing heat buildup and brake fade
• Addresses issues with rust and corrosion due to rust-resistant coating
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Enhances wet weather braking through drilled and slotted design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 21 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the vehicle’s hub using the 100 mm bolt circle diameter and 14.2 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping. This rotor is directional; install with the correct orientation for optimal performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable performance for Pontiac LeMans brake system replacements.
