PAD WEAR INDICATOR, PROBE FOR PAD WEAR INDICATOR, AND DISPLAY DEVICE FOR PAD WEAR INDICATOR

摘要

PURPOSE: To detect disconnection condition of each electric wire passage, and display an abrasion amount stepwise so as to inform the change timing of a pad by providing with a plurality of electric wire passages whose distances from the folding back part of a probe rubbing together with a break pad to the pad are different from each other. ;CONSTITUTION: A probe 10 is abraded from a top end side by abrasion of a break pad, the terminal 11 disconnection part of a first detecting part formed in the vicinity of the top end of the probe 10 is started on opening, the disconnection part is scraped off by being brought in contact with a break disk, and it is scraped off completely. At this time, electrification of an indicator lamp is carried out, and the character of 1/2 of the light transmitting lamp 21 of an indicator 20 is lighted. Therefore, a driver can know enough using of the probe 10, and on the other hand, the driver can know abrasion of the brake pad. When the driver is used the brake pad leaving as it is, the terminal 11 disconnection part of a second detecting part is started on opening, the disconnection part is scraped off by being brought in contact with the break disk, and it is scraped off completely. At this time, the character of change is lighted on the indicator 20, and the driver can be known a change timing. The driver can know abrasion condition so as to prevent uneasiness caused by sudden information.;COPYRIGHT: (C)1995,JPO
