ACDelco 18A82311AC Coated Disc Brake Rotor

The ACDelco 18A82311AC is a coated disc brake rotor engineered to deliver reliable, consistent braking performance. Backed by General Motors, this rotor is manufactured to meet precise specifications for fit, form, and function — making it a quality replacement for a wide range of vehicles.

The corrosion-resistant coating is robotically applied and baked on, helping to prevent brake pulsation, inhibit rust from rain, snow, and road sprays, and reduce the risk of the rotor seizing to the hub. The rotor is mill-balanced and features a non-directional ground finish that helps extend brake pad life and minimize rotor thickness variation over time.

Key Features:

• Coated disc brake rotor with baked-on corrosion protection
• Helps prevent brake pulsation and hub seizure
• Non-directional ground finish minimizes thickness variation and extends pad life
• Manufactured with multiple alloys for improved heat dissipation
• Mill-balanced for proper function — no additional balancing weights required
• Quality validated for correct metallurgy and brake plate thickness
• Ready to install out of the box — no machining required
• Backed by General Motors

This ACDelco coated brake rotor is a dependable aftermarket solution offering the confidence of GM-backed engineering. MPN: 18A82311AC.
