The star wheel on a drum brake is used when removing the brake drum.

Explanation:
In drum brakes, the star wheel adjuster controls how far the shoes sit from the drum. When you’re removing the brake drum, you back off the star wheel to retract the shoes, creating the extra clearance needed for the drum to slip off the hub. That’s why this handy adjuster is used during drum removal. It isn’t about releasing caliper tension or bleeding the system, and while the adjuster does change shoe proximity over time, its immediate purpose in this context is to free the drum by retracting the shoes.
