Detailed Description

Part number 4512-48244 is a rear brake service kit engineered for 2018-2020 Chevrolet Express 3500 and 2018-2020 GMC Savana 3500 models with the 3.54" gear ratio. The coated rotors are processed dry and ready for installation, which helps reduce prep time during a rear brake job. The pads are built for consistent friction output, and the included hardware is designed to restore proper caliper movement and spring tension on the listed applications.

What It Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weakened hardware
• Brake vibration related to rotor wear or finish issues
• Longer stopping distances from worn friction components
• Rust buildup on exposed rotor surfaces

Installation Notes and Tips

Use this kit on the rear axle only for the listed Chevrolet Express 3500 and GMC Savana 3500 applications. Inspect calipers, slides, and mounting points before installation, and verify the 3.54" gear ratio match before ordering. Clean the hub surface thoroughly and follow standard brake bedding procedures after installation to help the pads and rotors seat evenly.

Quality Assurance

DFC states that the rotors are machined to OE specifications, fully inspected for critical dimensions, and balanced where required. The rotors include a 12-month warranty against defects in material and workmanship.
