• Directional drilled and slotted surface for improved brake pad bite and heat management
• Vented rotor design to reduce brake fade
• Nominal thickness of 25.7 mm with a discard thickness of 24.7 mm
• Rust-resistant zinc silver hat finish and plain disc finish
• 5 bolt holes with 12x1.75 mm diameter and 135 mm bolt circle diameter
• Overall diameter of 308 mm and height of 104 mm

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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction offers rotors designed with both drilled holes and slots on the braking surface. This combination helps to evacuate gases, dust, and water more effectively than standard rotors, improving braking consistency. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor faces to dissipate heat generated during braking. The rotor's directional surface pattern, featuring both drilled holes and slots, enhances pad bite and helps maintain clean contact surfaces. The rotor measures 308 mm in outside diameter with a height of 104 mm, fitting securely on the Ford F-150's 5-lug wheel hubs with a 135 mm bolt circle diameter. The nominal thickness is 25.7 mm, with a discard thickness of 24.7 mm, ensuring safe replacement intervals. The zinc silver finish on the rotor hat provides rust resistance, while the plain disc finish maintains structural integrity.

Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping caused by excessive heat buildup
• Helps maintain consistent brake pad contact and bite
• Protects against corrosion for longer rotor life

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 24.7 mm to maintain safe braking performance. Use the correct torque specifications for the 5 lug bolts with 12x1.75 mm diameter to secure the rotor properly. Directional rotors must be installed with the rotation arrow pointing in the correct direction of wheel rotation to function as designed.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and vented design contribute to durability and consistent braking performance.
