A patient transport apparatus includes a base, a patient support deck, a plurality of wheels, a plurality of brakes, and an electro-mechanical braking system. The electro-mechanical braking system includes a linkage and an electrical braking assembly. The linkage is operatively coupled to the brakes to place the brakes in a braked state, a released state, or other state. The electrical braking assembly includes an actuator assembly that moves the linkage via a driving member. A user interface includes an input control for user engagement. A brake control circuit includes a hold circuit to generate an enable signal with a predetermined voltage in response to the user engagement with the input control, maintain the enable signal for a predetermined period following user disengagement with the input control, and operate the actuator assembly with the enable signal to move the driving member within the predetermined period.
