A braking system for a final drive for a wheel assembly of an independently powered wheeled vehicle. The system includes a service brake having a displaceable element actuatable to retard rotation of the individual wheel assembly. A park brake is positioned closely adjacent to the service brake and is actuatable independently of the service brake to displace the displaceable element to retard rotation of the wheel. Both the service brake and park brake are accessible without disturbing an electric motor with which they are associated.


1. A braking system for a final drive for a wheel assembly, the braking system comprising: a brake housing having a bore with at least one uniform diameter section; a service brake actuator disposed within the bore of the brake housing, the service brake actuator being an annular element configured to be axially displaced under fluid pressure to retard rotation of the wheel assembly by engaging one or more brake discs contained within the brake housing;a park brake actuator disposed within the bore of the brake housing adjacent to the service brake actua...
