The basic idea of the prediction is founded on our previously published theory, in which the vapour lock is mainly caused by the bubble growth below the brake-fluid boiling point. According to this theory, a brake pedal becomes spongy due to the bubble growth, and fluid pressure may be lost upon further growth. Hence it is most important for drivers to be able to determine the beginning of the bubble growth in a hydraulic brake because they can predict the vapour lock. Therefore, we developed an alarm device for vapour lock, which can sense the bubble growth, using a simple sensor with 2 short conducting wires embedded in disk calliper housing. Using this device, we are altered to bubble growth in the disk calliper housing by the light of the alarm lamp. In this report, the outline of this alarm device and the significance of the adoption of the device in automobiles are explained.
