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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features such as drilled holes and slots. These features help to evacuate gases, dust, and water from the braking surface, improving brake pad contact and reducing fade. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving conditions.

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 rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor's outside diameter measures 235 mm, with an overall height of 45 mm. It includes four bolt holes with a diameter of 13 mm arranged on a 100 mm bolt circle diameter, matching the stud/lug hole pattern for secure fitment. The directional surface type with slotted and drilled features optimizes braking performance under demanding conditions.

Applications and Problem Solving

• Reduces brake fade caused by overheating during extended braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner braking components
• Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
• Maintains consistent braking performance for Ford Aspire and Kia Rio vehicles

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 100 mm bolt circle diameter and 13 mm bolt hole diameter. Proper torque specifications should be followed to secure the rotor. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor with rust-resistant coatings and zinc silver finishes to enhance durability. The part number 631-21000R is designed to meet OEM specifications for Ford Aspire and Kia Rio models. While no explicit warranty information is provided, the product is engineered to maintain performance within specified thickness limits and fitment requirements.
