About this product

ACDelco Silver Disc Brake Rotors are a quality, high value alternative for General Motors vehicles as well as most makes and models and are backed by General Motors. When your daily commute or heavy traffic driving is interrupted by annoying steering wheel vibrations or a pulsating brake pedal, it is often a sign that your braking surfaces have become warped or deeply scored. Replacing worn components with these coated disc brake rotors restores smooth, predictable stopping power by providing a clean, flat surface for the brake calipers and pads to firmly grip. These disc brake rotors mount to the wheel hub and give the brake pads a stable, true surface to clamp against, helping restore smooth, quiet deceleration and predictable stopping power in daily commuting or repeated heavy stops. Its baked-on coating helps prevent brake pulsation, helps prevent the rotor from seizing to the hub, and provides superior rust prevention against harsh elements, while the non-directional ground finish extends brake pad life and minimizes thickness variation for consistent braking. ACDelco Silver parts are a good choice for many vehicles on the road today.
