About the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface to improve water and gas evacuation. This design helps maintain consistent brake pad contact and reduces brake fade under demanding conditions. The zinc black coating on the rotor hat provides corrosion resistance, extending the rotor's service life on vehicles such as the Ford Explorer and Mercury Mountaineer.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type rotor with a 301 mm outside diameter and a 58.2 mm overall height, engineered to meet the specifications of select Ford and Mercury SUVs. The rotor features a directional surface with both drilled holes and slots, which aid in heat dissipation and debris removal during braking. The nominal thickness of 12.1 mm ensures durability, while the discard thickness of 11 mm indicates when replacement is necessary. The rotor’s hat is finished with a rust-resistant zinc black coating to protect against corrosion, and the 5-bolt hole pattern with a 114.3 mm bolt circle diameter matches factory specifications for secure fitment.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Explorer and Mercury Mountaineer
• Improves braking performance in wet or dusty conditions due to drilled and slotted design
• Reduces brake fade during heavy braking or towing
• Prevents rust and corrosion on rotor hats for longer service life
• Restores proper rotor thickness to maintain safe braking distances

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (11 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Use proper torque specifications for the 5 lug bolts (13.7 mm diameter)
• Check compatibility with Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer models
• Inspect brake pads for wear and replace if necessary when installing new rotors

Quality Assurance

Dynamite Friction manufactures the 633-54178L rotor to meet OEM standards for fit and function. The rust-resistant zinc black coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, this rotor is designed to maintain consistent braking performance and meet the demands of Ford Explorer and Mercury Mountaineer vehicles.
