A brake shoe that wraps into the drum as it is applied is said to be a/an:

The situation describes self-energizing action in a drum brake. When the brake is applied, the geometry and rotation of the drum cause the lining to wrap into the drum, which increases the clamping force and braking torque without extra input from the wheel cylinder. This is why this behavior is generally called energized or self-energizing—the brake shoe uses the drum’s motion to enhance braking. The term flush-fit describes how tightly the shoe sits against the drum face, not the self-wrapping action, so it doesn’t match the described effect.
