A vehicle braking control method is provided. When a driver intends to drive a vehicle after the delivery of the vehicle or a factory mechanic intends to test the vehicle before the delivery of the vehicle after the engine is turned on even when a warning light is turned on due to the insufficiency of the brake fluid, a warning signal indicating that a level sensor is malfunctioning is generated using an instrument cluster, or driving torque of the engine is limited while a warning phrase indicating the insufficiency of the brake fluid is displayed using the cluster. Therefore, the vehicle may travel at a minimum speed. Thus, the driver is enabled to drive the vehicle to a safe place. Accordingly, a secondary accident is prevented and a subsequent maintenance operation is easily performed.
