On a combination of devices there is an alarm lamp of an emergency condition of brake system. If the system is perfectly in order also the lever of a lay brake is lowered, the lamp does not burn. If burns, check up level of a brake liquid in a feeding tank. It is located on forward walls of a body under a cowl. If the lamp lights up during movement, it can mean that in one of contours there is no brake liquid and it does not work. The second contour, as a rule, is still efficient, and you can cautiously reach to the house. At normally working brakes level of a brake liquid can go down because of deterioration of brake overlays. Level of a brake liquid in a feeding tank should is between marks min and max (
