- Vented rotor design to reduce heat buildup
- Nominal thickness of 30.1 mm with discard thickness at 28.45 mm
- Zinc silver hat finish with rust-resistant coating
- 5 bolt holes with 1/2-20 diameter and 114.3 mm bolt circle diameter
- Overall diameter of 272 mm and center hole diameter of 70.5 mm
Detailed Product Features and Specifications
This Dynamite Friction DFC Brake Rotor (631-56004R) is constructed with a vented design that allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water, contributing to consistent brake pad contact and improved performance under demanding conditions. The directional brake surface ensures optimal rotation alignment for enhanced braking efficiency.
The rotor’s nominal thickness is 30.1 mm, with a discard thickness of 28.45 mm, indicating when replacement is necessary to maintain safe braking. The rotor features a plain disc finish and a zinc silver hat finish that includes a rust-resistant coating to protect against corrosion. It has five bolt holes sized 1/2-20 with a bolt circle diameter of 114.3 mm, matching the stud/lug hole circle diameter, ensuring proper fitment on Mercury Montego vehicles.
About the DFC Brake Rotor - Drilled and Slotted - Silver Line
The DFC Brake Rotor - Drilled and Slotted - Silver product line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant silver finish. This line is designed to provide enhanced heat management and braking consistency, particularly for vehicles requiring vented rotors with directional surfaces. The zinc silver hat finish and rust-resistant coating extend rotor life by reducing surface corrosion.
Applications and Problem Solving
- Replacement rotor for worn or warped brake rotors on Mercury Montego
- Improves heat dissipation to reduce brake fade during heavy braking
- Helps maintain consistent braking performance in wet or dusty conditions
- Addresses rotor corrosion issues with rust-resistant coating
- Restores proper rotor thickness for safe braking operation
Installation Notes and Tips
Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 30.1 mm. Clean the rotor surface to remove any protective coatings or debris before mounting.
Quality Assurance
Dynamite Friction manufactures the 631-56004R rotor to meet OEM specifications for fit and function on Mercury Montego models. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor is designed for reliable, long-term braking performance when installed and maintained properly.
