Details on 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 reduce heat buildup. This product line is designed to maintain braking efficiency under demanding conditions by promoting better ventilation and debris removal. The silver zinc coating on the rotor hat enhances corrosion resistance, extending rotor life on compatible vehicles.

Technical Description and Features

This vented disc brake rotor features a directional surface with both drilled holes and slots, which help dissipate heat and gases generated during braking. The rotor’s nominal thickness of 29.1 mm ensures durability, while the discard thickness of 27.5 mm indicates when replacement is necessary. The rotor’s 6-bolt pattern with a 127 mm bolt circle diameter matches the factory specifications for Buick Ascender, Chevrolet Trailblazer, GMC Envoy, Isuzu Rainier, and SSR models. The zinc silver hat finish provides rust resistance, and the plain disc finish supports consistent pad contact.

Applications and Problem Solving

• Compatible with Buick Ascender, Chevrolet Trailblazer, GMC Envoy, Isuzu Rainier, and SSR models
• Addresses brake fade caused by excessive heat during heavy braking
• Reduces brake dust and debris buildup on rotor surface
• Improves wet weather braking performance through water dispersion
• Helps prevent rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

Ensure the rotor surface is clean and free of oil or debris before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s hub assembly. Use proper torque specifications for the 6 lug bolts to avoid warping. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating on the rotor hat helps extend service life. Please consult product documentation or contact the manufacturer for warranty details specific to part number 631-48052L.
