In _____ brakes, the springs in brake shoe react & expand from pressure in piston. The brake shoe then applies pressure to the inner surface of the drum.

Explanation:
In drum brakes, hydraulic pressure from the master cylinder pushes wheel-cylinder pistons outward, causing the brake shoes to expand so their linings press against the inner surface of the rotating drum. This friction slows the wheel. When the pressure releases, return springs pull the shoes back away from the drum. This is different from disc brakes, where pads are pressed against a rotor by calipers, and there isn’t a drum with shoes expanding from a piston. ABS is a braking system feature, not the basic brake type.
