Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on providing enhanced braking efficiency through a combination of drilled holes and precision slots. The vented design improves airflow to reduce heat buildup during braking, which helps prevent brake fade. The rotor’s directional surface pattern is engineered to channel gases and debris away from the contact area, maintaining consistent pad contact and braking response.

The rotor measures 280 mm in outside diameter with an overall height of 44 mm. It has a nominal thickness of 22 mm and a discard thickness of 19.4 mm, ensuring a long service life before replacement is necessary. The zinc silver coating on the hat offers corrosion resistance, extending the rotor’s durability in various driving conditions. The rotor features four bolt holes with a 12.5 mm diameter and a 100 mm bolt circle diameter, matching the factory specifications for Hyundai Accent and Kia Rio models.

Applications and Problem Solving

• Restores braking performance on Hyundai Accent and Kia Rio vehicles
• Reduces brake fade caused by overheating during extended braking
• Improves water and debris evacuation for consistent braking in wet conditions
• Minimizes rotor warping and vibration through vented design
• Prevents rust and corrosion with zinc silver coating

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is within the nominal range and above the discard thickness to maintain safety standards. Use proper torque specifications for the four 12.5 mm bolt holes to secure the rotor firmly. This rotor is directional; install it according to the indicated rotation direction to optimize performance and longevity.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Hyundai Accent and Kia Rio vehicles. The rust-resistant zinc silver finish helps maintain rotor integrity over time. While no specific warranty information is provided, the rotor’s design and materials support reliable, consistent braking performance under normal operating conditions.
