• DFC GEOSPEC coated rotors resist rust and arrive dry for installation.
• Non-directional rotor finish supports quicker pad bed-in and smoother stops.
• 5000 Advanced brake pads are post-cured for stable friction performance.
• Rubber-steel-rubber shims help reduce noise and vibration.
• Part number 4502-45073 identifies this complete brake kit.

Detailed description

Dynamic Friction 4502-45073 is a rear disc brake kit for the Buick Envision that brings together matched rotors and pads in one service package. The GEOSPEC rotor coating is designed to fight corrosion while the rotor casting and machining are built to OE specifications for durability, reliability, and stability. The pads are formulated for consistent friction, with scorching and post-curing steps that reduce initial break-in and support predictable pedal response.

This kit is a practical choice for a rear brake refresh on the Buick Envision when you want rotor and pad components selected to work together. The 4502-45073 kit also reflects the DFC GEOSPEC Rotors with 5000 Advanced Brake Pads product line, which focuses on coated rotor protection and pad refinement for everyday braking service.

What it is used for

• Replacing worn rear brake rotors and pads.
• Addressing brake noise from worn friction material or pad shims.
• Restoring braking feel after rotor wear or surface corrosion.
• Improving pad bed-in after a brake service.
• Servicing a Buick Envision rear brake system with matched components.

Installation notes and tips

Fits 2019-2020 Buick Envision, rear. The rotors are processed dry and ready to install without additional preparation. For best results, clean the hub mounting surface before installation and follow the vehicle manufacturer’s brake service procedure, including proper pad bedding after the repair.

Quality assurance

DFC states that the rotors are machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. The rotors include a 12-month warranty against defects in material and workmanship.
