ACDelco 18K16122B Front Disc Brake Caliper Guide Pin Seal

The ACDelco 18K16122B is a professional-grade front disc brake caliper guide pin seal designed as a high-quality replacement component for your vehicle's disc brake system. Also known as a caliper slide pin boot or caliper guide pin bushing seal, this part helps maintain proper caliper alignment and movement for consistent, reliable braking performance.

The guide pin seal protects the caliper slide pins from contamination by moisture, dirt, and debris, allowing the caliper to move freely and evenly. A worn or damaged seal can lead to uneven pad wear, brake drag, or caliper seizure, making timely replacement essential to brake system health.
