Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction features rotors designed with both drilled holes and slots to improve brake pad bite and heat dissipation. This product line focuses on maintaining consistent braking performance under demanding conditions by reducing brake fade and helping to evacuate gases and debris from the rotor surface. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Product Specifications and Features

This solid rotor measures 285 mm in outside diameter and 57.9 mm in height, fitting the bolt pattern of 5 lug holes spaced on a 114.3 mm circle. The drilled and slotted surface is directional, enhancing braking efficiency and pad cleaning. The rotor’s nominal thickness is 12 mm, with a discard thickness of 11 mm, ensuring clear service limits for safety. The zinc silver hat finish offers rust resistance, which is critical for off-road capable vehicles like the Jeep Wrangler and Liberty.

Applications and Problem Solving

• Compatible with Jeep Liberty, TJ, and Wrangler models requiring 285 mm rotors
• Addresses brake fade caused by heat buildup during heavy braking
• Helps reduce brake dust accumulation on rotor surface
• Improves wet weather braking performance by channeling water away
• Prevents premature rotor corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed on compatible Jeep models with a 5-lug, 114.3 mm bolt circle pattern. Verify rotor thickness before installation; replace if below the discard thickness of 11 mm. Directional rotors must be mounted following the indicated rotation direction for optimal performance. Clean the rotor surface of any protective coatings before installation to avoid brake pad contamination.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for Jeep Liberty, TJ, and Wrangler vehicles. The rust-resistant zinc silver finish and precise machining ensure durability and consistent braking performance. While no specific warranty information is provided, adherence to discard thickness and proper installation will maintain safety and reliability.
