Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Black is a solid rotor designed to meet the braking demands of Ford Explorer, Explorer Sport, Mercury Mountaineer, and Ford Ranger models. The rotor features a drilled and slotted surface type that helps improve heat dissipation and reduce brake fade during heavy braking conditions. The directional brake surface ensures proper alignment for optimal performance and longevity.

The rotor’s nominal thickness is 12 mm, with a discard thickness of 11 mm, indicating when replacement is necessary to maintain safe braking. The zinc black coating on the hat provides rust resistance, extending the rotor’s service life in various driving environments. With 5 bolt holes sized at 14.5 mm diameter and a bolt circle diameter of 114.3 mm, this rotor is designed for precise fitment on compatible vehicles.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking efficiency. This product line is engineered to provide improved heat dissipation and debris removal, which helps maintain consistent brake pad contact and reduces the risk of brake fade. The black zinc finish on the rotor hat adds corrosion resistance, making it suitable for vehicles exposed to varying weather conditions.

Applications and Problem Solving

• Compatible with Ford Explorer, Explorer Sport, Mercury Mountaineer, and Ford Ranger models
• Helps reduce brake fade during heavy or repeated braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust and debris buildup on the rotor surface
• Provides corrosion resistance to extend rotor lifespan

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (5 holes, 14.5 mm diameter, 114.3 mm bolt circle) matches the vehicle hub. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 11 mm. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction manufactures the 633-54142L rotor to meet industry standards for durability and performance. The rust-resistant zinc black finish on the rotor hat helps protect against corrosion. While no specific warranty information is provided, Dynamite Friction products are generally designed to comply with OEM specifications for reliable braking performance.
