Abstract

A hydraulic circuit for an adaptive park braking system and method of operation thereof. The method of operating an adaptive park braking system includes providing a vehicle having a motor, a front axle system, a rear axle system, wherein the front axle system has one or more front axle braking systems and the rear axle system has one or more rear axle braking systems. Identifying when the vehicle is engaged in a digging operation. Disconnecting the front axle system or the rear axle system from driving engagement with the motor of the vehicle. Activating the one or more braking systems of the disconnect axle system to apply an amount of force to the disconnected axle system of the vehicle. Then applying an amount of torque with the motor to the axle system in driving engagement with the motor.
