ABSTRACT:
A dual brake mechanism for a vehicle having a first disc brake assembly associated with a first output drive member and a second disc brake assembly associated with an opposite second output drive member includes a primary brake actuator for generating a force engaging the first disc brake assembly and a plurality of push elements for mechanically transmitting that force as a reaction laterally to the second disc brake assembly and simultaneously engaging both. The primary brake actuator features a single actuation chamber for providing the engagement force when pressurized. This avoids the full duplication of componentry at the opposite sides of the vehicle. The dual brake mechanism can be compactly integrated with a steering differential and a secondary parking brake actuator.
