PURPOSE:To detect whether a brake tube contains the air or not automatically. CONSTITUTION:The pressure in a brake tube is detected by detecting the variation in the diameter of the tube by means of an inner presure sensor 11 installed on the outer side of the brake tube. The standard value of the inner pressure of the tube when a brake pedal is depressed is stored in a memory 22 beforehand, and the measurement value of the inner pressure detecting sensor 11 and the standard value are mutually compared. The result of the comparison is displayed on a display 24. As a result, it can be detected whether the air is enough in the brake tube of a brake system or not easily without requiring any skill.
