About the DFC Brake Rotor - Drilled and Slotted - Silver Line
The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This product line is tailored for vehicles requiring enhanced braking performance with corrosion-resistant finishes, making it suitable for Dodge Charger Daytona and Jeep Grand Cherokee applications where durability and consistent braking are priorities.
Detailed Product Description
This disc brake rotor features a plain disc finish with a zinc silver hat finish that provides rust resistance, helping maintain rotor integrity over time. The drilled and slotted surface design aids in reducing brake fade by allowing gases and heat to escape more efficiently during braking. With a 5-bolt hole pattern and a 127 mm bolt circle diameter, this rotor fits securely on compatible Dodge and Jeep models. The rotor’s directional surface ensures proper installation orientation for optimal performance. The nominal thickness of 22 mm and discard thickness of 20 mm provide clear service limits for maintenance.
Applications and Problem Solving
- Improves braking performance on Dodge Charger Daytona and Jeep Grand Cherokee vehicles
- Reduces brake fade during heavy or repeated braking
- Helps prevent rotor warping caused by excessive heat buildup
- Minimizes rust and corrosion for longer rotor life
- Enhances pad bite and braking consistency in wet or dusty conditions
Installation Notes and Tips
Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify bolt hole alignment with the 5-lug pattern and 127 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 22 mm and is above the discard thickness of 20 mm. Clean the rotor surface to remove any protective coatings or debris before mounting to ensure proper pad contact.
Quality Assurance
Dynamite Friction rotors are manufactured to meet OEM specifications for fit and function. The rust resistant coating and zinc silver hat finish contribute to durability and corrosion protection. While no specific warranty information is provided, adherence to service thickness limits and proper installation will help maintain rotor performance and safety.
