ACDelco 18A2677C Gold Fully Coated Disc Brake Rotor

The ACDelco 18A2677C is an ACDelco Gold fully coated disc brake rotor engineered as a high-quality alternative to Original Equipment (OE) parts. Manufactured to meet strict specifications for fit, form, and function, this rotor is a trusted replacement choice for General Motors vehicles as well as a wide range of other makes and models.

Key Features:

• Full-coverage protective coating on the hat, vanes, and braking surfaces helps prevent rust and corrosion, extending rotor service life
• Baked-on coating helps prevent brake pulsation and reduces the risk of the rotor seizing to the hub
• Full cast iron construction delivers strength, durability, and consistent thermal performance under repeated braking cycles
• Non-directional ground finish minimizes thickness variation and extends brake pad life for smooth, consistent stopping
• Independently tested for balance, noise/vibration/harshness (NVH), and durability to ensure quiet, reliable brake operation
• Quality validated for proper metallurgy and correct brake plate thickness with tighter tolerances aligned to GM OE specifications
• No ABS sensor ring included — direct replacement design

ACDelco Gold brake rotors are backed by General Motors and validated through an extensive testing regimen to deliver the quality, performance, and dependability expected from a trusted OE supplier. The 18A2677C is sold individually and is designed for straightforward installation as a direct OE-style replacement.
