A method of controlling a vehicle during a braking operation includes providing a first and a second brake actuator, a brake input device, a steer input device, and a cross-drive transmission having two outputs and a controller. The method includes detecting a first output speed at the first output and a second output speed at the second output, and receiving a brake input request and a steer input request. The method also includes determining a differential output speed based on the first output speed and the second output speed, and comparing the differential output speed to a first threshold, the brake input request to a second threshold, and the steer input request to a third threshold. The method includes determining the first or the second output is locked during the braking operation, and controlling the first or the second brake actuator based on which output is determined to be locked.
