  "textContent": "Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader comprises a controller storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve increases as a pedal angle θ of a brake pedal increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer is equal to or less than the predetermined pedal angle θth, the controller , calculates the brake valve control pressure Pi based on the selected one control characteristic.",
