What is an Emergency Break Windup Tool Car?
An Emergency Break Windup Tool Car, often simply called a brake spoon or star wheel adjuster, is designed to retract the brake shoes within a drum brake assembly. This action is necessary when performing maintenance such as replacing brake shoes, drums, or hardware.

Types of Emergency Break Windup Tools

- Offset Brake Spoon: Designed for tight spaces or awkward angles, this tool has a bent or angled tip for improved access.

- Cube-Shaped Adjuster: Some vehicles utilize a cube-shaped adjuster instead of a star wheel, requiring a specialized tool with a square or rectangular tip.
