ACDelco 18A2679C Silver Coated Rear Disc Brake Rotor

The ACDelco 18A2679C is an ACDelco Silver coated rear disc brake rotor engineered as a high-quality, high-value alternative for General Motors vehicles as well as most makes and models, and is backed by General Motors. This rotor delivers reliable stopping power and is ready to install straight out of the box with no machining required.

Key Features:

• Robotic-applied, baked-on coating helps prevent brake pulsation, resists rotor-to-hub seizing, and provides superior rust protection against rain, snow, and corrosive road spray
• Non-directional ground finish minimizes rotor thickness variation and helps extend brake pad life
• Multi-alloy construction improves heat dissipation and overall braking performance
• Mill-balanced design ensures smooth rotor operation and reduces noise and vibration — no additional balancing weights needed
• Quality-validated metallurgy and correct brake plate thickness confirmed through rigorous testing
• Application-specific vane configuration maximizes airflow to keep the rotor running at optimal temperatures
• Backed by General Motors and tested to ACDelco quality standards

The ACDelco Silver line (formerly known as ACDelco Advantage) offers a dependable, cost-effective solution for everyday braking needs. The 18A2679C is the coated version of the 18A2679 rotor, providing added corrosion protection for extended service life.
