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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade under demanding conditions. The zinc silver hat finish and rust-resistant coating extend rotor life by protecting against corrosion, making it suitable for daily driving and moderate performance use on compatible Ford Fiesta and Focus models.

Technical Specifications and Features

This disc brake rotor is a solid type with a directional surface featuring both drilled holes and slots. The nominal thickness is 10.1 mm, with a discard thickness of 8.9 mm, ensuring clear service limits. The rotor measures 253 mm in outside diameter and 33 mm in height, fitting precisely with the 4-bolt pattern (bolt hole diameter 13.75 mm, bolt circle diameter 108 mm). The hat area is finished in zinc silver to resist rust, and the rotor surface is plain finished to maintain consistent braking performance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Ford Fiesta and Focus
• Improves heat dissipation to reduce brake fade during extended braking
• Helps maintain consistent braking performance under varied driving conditions
• Resists rust and corrosion for longer service life in humid or wet environments
• Compatible with vehicles requiring a 4-bolt, 253 mm diameter rotor

Installation Notes and Tips

• Verify compatibility with your specific Ford Fiesta or Focus model year before installation
• Ensure rotor thickness is above discard thickness (8.9 mm) before reuse
• Clean rotor surface before installation to remove any protective coatings or debris
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Inspect brake pads and replace if worn to ensure optimal rotor performance

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit and function. The rust-resistant coating and zinc silver hat finish provide added durability. While no specific warranty information is provided, adherence to installation and maintenance guidelines will help ensure reliable braking performance with part number 631-54049L on compatible Ford Fiesta and Focus vehicles.
