Hydroboost trucks use power steering pressure to assist the brakes, so this return hose carries fluid from the hydroboost unit and the cooler back to the reservoir. A leak here drops fluid level quickly, and on a hydroboost system low fluid means hard steering and a hard brake pedal at the same time, which is why it is worth fixing promptly.
