Brake system (VAZ-2110)

The brake fluid level in reservoir 2 (Fig. 44), installed on the main brake cylinder 1, is checked visually using the marks on the reservoir body, made of translucent plastic. With cover 3 removed and new brake shoe linings, the fluid level should be at the "MAX" mark. If the brake hydraulic drive is in good condition, a decrease in the fluid level in the reservoir is due to wear of the brake shoe linings. A decrease in the fluid level to the "MIN" mark indirectly indicates their extreme wear. In this case, it is necessary to check the condition of the linings, and there is no need to add fluid to the reservoir, since when new pads are installed, the fluid level in the reservoir will rise to normal.



The warning light of the emergency brake system signaling lights up when the fluid level in the reservoir drops below the "MIN" mark, which, in the case of partially worn or new brake pads, indicates a loss of tightness of the system and a fluid leak. In this case, add fluid only after the tightness of the system is restored.

When checking the brake fluid level in the reservoir, do not forget to also check the correct operation of the emergency level sensor, for which press on the central part of the protective cap 4 from above - when the ignition is on, the control lamp in the instrument cluster should light up.
