Abstract
Braking system for a stroller utilizes an actuator to move two brakes close to an axis to unlock the rear wheels of the stroller and away from the axis to lock the rear wheels. Each brake comprises a long arm. The brakes are disposed at the opposite sides of the axis. When the actuator is driven to rotate about the axis, the brakes move around the axis to have axial movement close to or away from the axis.
