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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. This product line features a zinc silver coating on the rotor hat to resist corrosion, extending rotor life. The vented design further supports cooling, making it suitable for trucks like the Ford F-150 that require consistent braking under load.

Technical Specifications and Features

This disc brake rotor features a vented design with a directional surface that is both drilled and slotted, enhancing braking efficiency by reducing heat buildup and preventing brake fade. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. With an outside diameter of 336 mm and an overall height of 45 mm, it fits precisely on compatible Ford F-150 models. The rotor includes six bolt holes, each 15.8 mm in diameter, arranged on a 135 mm bolt circle diameter, matching the vehicle's hub specifications. The zinc silver hat finish provides rust resistance, while the plain disc finish maintains a clean braking surface.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford F-150 trucks
• Improves heat dissipation to reduce brake fade during heavy towing or hauling
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances braking performance in wet conditions by channeling water away from the pad surface
• Prevents rust and corrosion on rotor hats to extend service life

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify that the rotor thickness is within the specified nominal and discard limits. Use the correct torque specifications for the six 15.8 mm bolt holes on the 135 mm bolt circle diameter. The directional drilled and slotted surface should be installed following the rotation direction indicated on the rotor to maintain optimal braking performance.
