A vehicle braking system having first and second brakes configured to apply a brake torque 50 to first and second wheels, a drivetrain coupled to the wheels and configured to transfer torque between the wheels, and a controller configured to detect a failure condition 52 resulting in one of the wheels becoming a non-braked wheel 54 and command the drivetrain to transfer brake torque to the non-braked wheel 56. A method of braking a vehicle is also disclosed, wherein the drivetrain transfers braking torque from the second wheel to the non-braked wheel. Preferably, the drivetrain transfers braking torque by locking a differential, through a transfer case, or through a transmission. The first and second wheels may be a combination of front and rear wheels, or both front or both rear wheels. The failure condition may be a failed hydraulic brake circuit, electrical brake circuit, or brake control module.
