Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors engineered for enhanced heat management and durability. The drilled and slotted design improves brake pad bite and helps evacuate gases and debris, while the zinc silver coating on the hat provides corrosion resistance. This rotor is designed to meet the specific braking demands of Toyota vehicles like the Corolla and Prius Prime.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking. The surface is both drilled and slotted, which aids in maintaining clean pad contact and improving wet weather braking. The rotor has a nominal thickness of 21.9 mm and a discard thickness of 19 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, extending the rotor's service life. With 5 bolt holes and a 100 mm bolt circle diameter, it fits securely on compatible Toyota models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Toyota Corolla and Prius Prime
• Improves heat dissipation to reduce brake fade during extended use
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust resistant coating
• Supports directional braking surface for optimized pad engagement

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 19 mm before installation. Clean the hub surface and mounting area to prevent runout. Use proper torque specifications for the 5 lug bolts to secure the rotor. The directional surface requires correct orientation to maintain braking efficiency. It is recommended to replace brake pads when installing new rotors for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for Toyota Corolla and Prius Prime models. The rust resistant zinc silver coating and vented design contribute to durability and consistent braking. While no specific warranty information is provided, the rotor is engineered for reliable service within recommended maintenance intervals.
