ACDelco 18A81099C Silver Coated Rear Disc Brake Rotor

The ACDelco 18A81099C is an ACDelco Silver coated rear disc brake rotor engineered to deliver reliable stopping performance for a wide range of GM and non-GM vehicles. As part of the ACDelco Silver lineup, this rotor offers a high-quality, high-value replacement option backed by General Motors.

Key Features:

• Corrosion-Resistant Coating: Baked-on coating helps prevent rust, reduces brake pulsation, and helps prevent the rotor from seizing to the hub
• Non-Directional Ground Finish: Minimizes thickness variation and extends brake pad life for consistent, even wear
• Mill-Balanced Construction: Balanced for smooth, quiet operation and reduced noise and vibration
• Multi-Alloy Construction: Built with multiple alloys to improve heat dissipation and braking performance under real-world thermal stress
• Validated Metallurgy: Engineered to meet proper plate thickness specifications for reliable, predictable braking
• ACDelco Silver Quality: High-quality, high-value option suitable for GM vehicles and most other makes and models

Replacing worn or scored rotors with the ACDelco 18A81099C restores smooth, predictable stopping power by providing a clean, flat surface for brake calipers and pads to firmly grip. This rotor mounts directly to the wheel hub and supports the full hydraulic braking system for confident, quiet deceleration in everyday driving conditions.
