- Directional slotted and drilled surface for improved brake cooling
- Vented rotor design to reduce heat buildup
- Rust-resistant zinc silver hat finish
- Nominal thickness of 30.1 mm with discard thickness at 28.45 mm
- 5 bolt holes with 1/2-20 diameter and 114.3 mm bolt circle diameter
- Overall diameter of 272 mm and height of 122.7 mm
Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver
The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with a combination of drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently than plain rotors, contributing to improved braking consistency. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life in various driving conditions.
Technical Specifications and Features
This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat generated during braking. The rotor's directional slotted and drilled surface enhances pad bite and helps maintain clean contact surfaces. With a nominal thickness of 30.1 mm and a discard thickness of 28.45 mm, the rotor ensures durability and safety margins for wear. The rotor features a plain disc finish and a zinc silver hat finish that resists rust and corrosion. It includes five bolt holes sized 1/2-20 with a bolt circle diameter of 114.3 mm, matching the Mercury Montego's specifications precisely.
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 prevent rust and corrosion on rotor hats for longer service life
- Enhances braking performance in wet conditions by channeling water away
- Maintains consistent braking feel with directional slotted and drilled design
Installation Notes and Tips
Ensure the rotor is compatible with your Mercury Montego model before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Torque the bolts to manufacturer specifications using the 5 bolt holes with 1/2-20 diameter and 114.3 mm bolt circle diameter. Check the rotor thickness regularly and replace when it reaches the discard thickness of 28.45 mm to maintain safe braking performance.
Quality Assurance
Dynamite Friction manufactures the 631-56004L rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat helps protect against corrosion. While no specific warranty information is provided, the rotor is designed for durability and consistent braking performance on Mercury Montego vehicles.
