Dynamic Friction 4512-45074 Disc Brake Kit - Rear

Brake Kit Overview

This Dynamic Friction disc brake kit is built for rear brake service on the 2019-2020 Buick Envision. It combines coated rotors, ceramic pads, and hardware in one application-specific package for a complete brake refresh.

Part number 4512-45074 is a direct-fit brake service kit for the Buick Envision rear axle, with components selected to match OE-style fitment and braking performance requirements.

Key Features

• Coated brake rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings.
• Dry-processed rotors arrive ready to install without additional cleaning or prep.
• Non-directional rotor finish promotes even pad bed-in and smoother braking.
• 5000 Advanced ceramic pads are post-cured and scorched for stable friction and reduced break-in time.
• Brake hardware uses PTFE coating, vulcanized rubber, and stainless steel for OE-style form and function.

Detailed Description

Dynamic Friction 4512-45074 is a rear disc brake kit for the 2019-2020 Buick Envision. The kit pairs DFC GEOSPEC coated rotors with 5000 Advanced ceramic pads and matching hardware, giving you the core components needed for a complete rear brake service.

The rotors are cast to G3000/G11H18 specifications, machined to tight tolerances, and finished for quieter, smoother stops. The coating is designed to help protect against corrosion while remaining safe for the friction material during use. The pads are formulated for stable braking performance, and the hardware is engineered to reduce caliper movement, noise, and uneven wear. If you are replacing worn rear brakes on a Buick Envision, part number 4512-45074 provides a fitment-specific solution.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake noise caused by worn pads or fatigued hardware.
• Uneven rear braking from corroded or stressed components.
• Longer stopping distances from worn friction surfaces.
• Rotor rust and surface corrosion after service intervals.
• Excessive caliper movement related to degraded hardware.

Installation Notes

Fits 2019-2020 Buick Envision, rear. Verify rotor and pad match before installation and inspect caliper condition, slide points, and mounting surfaces during service. The rotors are shipped dry and ready for installation, which helps reduce prep time during brake work.

Quality Assurance

DFC states that the rotors are manufactured to OE specifications and inspected for critical dimensions and balance. The rotors include a 12-month warranty against defects in material and workmanship.
