1. A method of actuating a brake on a caster wheel of a patient support apparatus to stop motion of the apparatus, the patient support apparatus including a support frame and a plurality of caster wheels supporting the frame, a patient support surface supported by the support frame, and at least one manually operable brake for manually braking the caster wheels, the patient support apparatus further including an actuator for selectively outputting a driving force and a control system, said method comprising: electrically coupling the control system to the actuator;generating actuating signals with said control system based on input at the patient support apparatus;transmitting the actuating signals to the actuator to thereby actuate the actuator to output a driving force; andmechanically coupling the driving force of the actuator with the manually operable brake to thereby actuate the manually operable brake and thereby brake the caster wheels. 2. The method according to claim 1, further comprising providing a user actuatable device responsive to pressure and selectively applying pressure to the user actuatable device wherein said applying pressure to the user actuatable device initiates said generating actuating signals. 3. The method according to claim 2, further comprising positioning the user actuatable device at or near the patient support surface. 4. The method according to claim 3, wherein the patient support apparatus includes a headboard, a footboard, and siderails, said positioning the user actuatable device includes positioning the user actuatable device at or near the headboard, a footboard, or siderails. 5. The method according to claim 1, further comprising supporting the support frame on a forward pair of bearings and a rearward pair of bearings, and providing a brake for each pair of bearings. 6. The method according to claim 5, further comprising providing an actuator for each brake. 7. The method according to claim 1, further comprising selectively drivingly decoupling the actuator from the brake to provide an override. 8. The method according to claim 1, further comprising providing a lock mechanism selectively prohibiting the release of the driving force. 9. The method according to claim 8, wherein said transmitting comprises releasably linking the actuator with the brake. 10. The method according to claim 9, further comprising selectively releasing the linking to thereby provide an override of the transmitting of the actuation force to the brake. 11. The method according to claim 8, further comprising monitoring the status of the brake, and displaying the status of the brake. 12. A patient support apparatus comprising: a patient support surface, said patient support surface being configured to move across a floor or ground surface;a manually operable brake operatively associated with said patient support surface; andat least one electrically powered actuator; andan electrical control system, said electrical control system selectively powering said actuator to actuate said brake. 13. The patient support apparatus according to claim 12, wherein said actuator is coupled to said brake, further comprising a manual override mechanism for drivingly decoupling said actuator from said brake. 14. The patient support apparatus according to claim 12, wherein said electrical control system has a button or a touch screen, said actuator powered by said control system in response to actuation of said button or said touch screen. 15. The patient support apparatus according to claim 12, further comprising a plurality of bearing members for moving said patient support surface across the floor or ground surface, each of said bearing members including a brake operatively associated therewith, and one or more of said brakes being configured to be actuated by said actuator. 16. The patient support according to claim 13, further comprising a locking mechanism selectively operable to prevent decoupling of said actuator and said brake, said locking mechanism controlled by said electrical control system. 17. The patient support according to claim 12, further comprising a mechanical link between said actuator and said brake and an override mechanism, said override mechanism configured to selectively drivingly decouple said actuator or said brake from said mechanical link. 18. The patient support according to claim 17, wherein said override mechanism comprises a manual override mechanism. 19. The patient support apparatus according to claim 12, further comprising a visual brake status indicator, said indicator indicating a status of said brake as one chosen from braking, steering, and neutral.
