10:10. Check of the sensor of level of brake fluid

Uncover a tank and check operation of the sensor of level of brake fluid. Include ignition. Ask the assistant to watch a control lamp of level of brake fluid in a combination of devices.
The pure screw-driver lower a float in a tank. The control lamp has to light up when the float falls below a tag of "Min" and to die away when the float rises above a tag.

Fig. 10.21. Check by an ohmmeter of operation of the sensor of level of brake fluid


The sensor of level of brake fluid can also be checked the ohmmeter connected to the sensor socket. Contacts of the sensor have to become isolated when the float falls below a tag of "Min" and to be disconnected when the float rises above a tag (fig. 10.21).
