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

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which is critical for maintaining braking performance during extended use. The rotor's nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary. The rotor measures 320 mm in outside diameter and 47.8 mm in height, fitting precisely on Acura MDX and TLX models. The 5 bolt holes, each 12.7 mm in diameter, are arranged on a 114.3 mm bolt circle diameter, ensuring proper fitment. The directional slotted and drilled surface enhances braking by channeling away debris and moisture.

Applications and Problem Solving

• Improves braking performance on Acura MDX and TLX vehicles
• Reduces brake fade during heavy or repeated braking
• Helps prevent rust and corrosion with zinc silver coating
• Maintains consistent brake pad contact through slotted and drilled design
• Supports heat dissipation to extend rotor and pad life

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 28 mm. Proper torque specifications should be followed to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures this rotor with rust-resistant coatings and precise machining to meet OEM standards. The zinc silver finish on the rotor hat provides additional corrosion protection. While no specific warranty information is provided, the rotor’s design and materials support reliable performance for Acura MDX and TLX brake systems.
