Brake Kit for Heavy-Duty Jeep and GM Trucks

The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit is built for front brake service on select Jeep and GM truck applications. Part number 4512-48147 combines coated rotors, ceramic pads, and brake hardware in one service kit for a cleaner, more complete brake job.

Key Features

• DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pad surface to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• OE-style hardware with PTFE coating, vulcanized rubber, and stainless steel construction
• Non-directional rotor finish for more even pad bed-in and quieter stops
• Dry-to-install rotor coating with no oil removal required

Product Details

DFC designed this brake service kit to match OE-style form, fit, and function while addressing common wear points in the braking system. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required. The ceramic pads are formulated for stable friction performance, and the included hardware is engineered to restore proper spring tension and caliper movement on worn brake assemblies. This part number 4512-48147 is a practical choice for drivers servicing Jeep J20 and Chevrolet/GMC front brake applications where corrosion resistance, consistent pedal feel, and reduced brake noise matter.

What It Helps Address

• Brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weak hardware
• Longer stopping distances from worn friction material
• Rotor rust and surface corrosion on exposed brake components
• Harsh braking feel from inconsistent pad-to-rotor contact

Installation Notes

Inspect calipers, hoses, and slide points before installation. Clean the hub face, verify rotor runout, and follow the vehicle-specific brake service procedure for pad bedding. The coated rotors are shipped dry and ready to install, which helps reduce prep time during a front brake service on Jeep J20, Chevrolet K20, and GMC K2500 applications.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, processed to tight machining tolerances, and checked through final inspection for critical attributes. The rotors include a 12-month warranty against defects in material and workmanship. DFC 5000 Advanced pads are post-cured and scorched for stable friction performance, and the hardware kit uses corrosion-resistant materials to support consistent brake operation.
