Accessory guideBrake Pad Spreader and Caliper Tool

This guide provides a complete, professional walkthrough for using a brake pad spreader and caliper tool to retract disc brake pistons without damaging seals, boots, or the caliper housing. It is written for working mechanics and serious DIYers who already understand basic brake service but want a disciplined, repeatable method for piston retraction across the many caliper designs found in modern vehicles. You will learn how to select the correct spreader or rewind tool for single, twin, and integrated parking-brake calipers, set it up safely, execute the retraction step by step, and interpret the results with worked examples drawn from real diagnostic jobs. By the end, you will be able to retract pistons confidently, recognize when a caliper is beyond a simple spreader's reach, and know exactly when to stop and call in a professional.
