ACDelco 18A82488C Coated Disc Brake Rotor

The ACDelco 18A82488C is a coated disc brake rotor engineered to restore smooth, quiet deceleration and confident stopping power. As part of the ACDelco brake component lineup, this rotor is manufactured to meet specifications for fit, form, and function for General Motors vehicles as well as a wide range of other makes and models.

Key Features:

• Baked-on protective coating helps prevent brake pulsation, resists rotor seizing to the hub, and provides superior rust and corrosion protection against harsh elements
• Non-directional ground finish minimizes rotor thickness variation and extends brake pad life for consistent, even braking performance
• Multi-alloy construction improves heat dissipation under real-world thermal stress, supporting reliable braking during daily commutes and repeated heavy stops
• Mill-balanced design validated for proper metallurgy and plate thickness to reduce noise, vibration, and harshness (NVH)
• Direct-fit replacement mounts to the wheel hub and provides brake pads a stable, true clamping surface
• Manufactured and validated through an extensive ACDelco quality testing regimen

The "C" suffix in the part number designates this as a coated rotor variant, offering enhanced corrosion resistance compared to standard non-coated versions. This rotor supports the full hydraulic braking system and helps maintain consistent, vibration-free stopping without steering wheel shimmy or pedal pulsation.
