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. This design helps maintain consistent braking performance and reduces brake fade. The zinc silver hat finish provides corrosion resistance, extending rotor life, especially in environments prone to rust. This rotor line is tailored for drivers who require dependable stopping power with enhanced rotor cooling and surface durability.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional surface pattern, featuring both drilled holes and slots, aids in removing brake dust and gases, which can otherwise reduce braking efficiency. The rotor’s nominal thickness is 23 mm, with a discard thickness of 21 mm, ensuring safe replacement intervals. The rotor’s bolt hole diameter and stud/lug hole diameter are both 12.75 mm, with four holes arranged on a 114.3 mm bolt circle diameter, matching the Honda Prelude’s specifications precisely.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Honda Prelude models
• Improves heat dissipation to reduce brake fade during aggressive or repeated braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Reduces brake pad glazing by efficiently removing gases and debris
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 21 mm. The rotor is designed for a four-bolt pattern with a 114.3 mm bolt circle diameter, compatible with Honda Prelude brake assemblies. Clean the rotor surface before installation to remove any protective coatings or residues. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fitment and performance on Honda Prelude vehicles. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the rotor is engineered to maintain structural integrity and braking efficiency within the specified thickness limits.
