About 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 heat dissipation and reduce brake fade. The silver zinc coating on the hat and rust resistant finish help protect the rotor from corrosion, making it suitable for vehicles like the Toyota Mirai and Prius V that require reliable braking components with enhanced durability.

Product Details and Specifications

This solid rotor features a slotted and drilled surface type designed to channel away gases and debris generated during braking, which helps maintain consistent pad contact and braking efficiency. The rotor’s nominal thickness is 12 mm, with a discard thickness of 10.5 mm, indicating when replacement is necessary to maintain safety. The zinc silver hat finish and rust resistant coating provide protection against corrosion, extending the rotor’s service life. The rotor is directional, meaning it is designed to be installed in a specific orientation to maximize performance. With 5 bolt holes and a bolt circle diameter of 114 mm, it fits securely on compatible Toyota models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Toyota Mirai and Prius V
• Improves heat dissipation to reduce brake fade during extended braking
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion-related rotor damage
• Maintains consistent braking performance under varied driving conditions

Installation Notes and Tips

Ensure the rotor is installed in the correct directional orientation as indicated by the drilled and slotted pattern. Verify that the rotor thickness is above the discard thickness of 10.5 mm before installation. Clean the rotor surface and hub mounting area to remove any debris or rust for proper fitment. Use the correct torque specifications for the 5 lug bolts to secure the rotor firmly. This rotor is compatible with Toyota Mirai and Prius V models that match the specified bolt pattern and dimensions.
