Final answer:
An automatic brake adjuster compensates for the wear of brake shoes, maintaining brake function. It is a component of varying brake systems, including regenerative and power brakes.
Step-by-step explanation:
The device which helps to automatically compensate for the wear of the brake shoes is known as an automatic brake adjuster. It ensures that the brakes are functioning optimally as the brake shoes wear down over time due to friction. This mechanism is part of a vehicle's brake system, which may include different types of brakes, such as regenerative brakes that convert kinetic energy into electrical energy or power brakes, which use a motorized pump to aid in braking.
