Checking the brake fluid level

Due to the operation of the front disc brakes, the fluid level, even in a perfectly serviceable brake system, decreases with increasing number of kilometers traveled. This is because the relatively large pistons of disc brake cylinders move further due to worn pads, increasing the volume of the cylinder. As a result, the liquid level in the tank drops.

Thus, a normal, slow decrease in the brake fluid level should not cause alarm. If you know exactly what the brake fluid level was with new and worn disc brake linings, then by the fluid level you can determine how worn the lining is. When the disc brake pads are changed, the pistons in the disc brake mechanism should be pushed back, due to which the fluid level in the reservoir rises again. If brake fluid has been unreasonably added to a system with worn linings, it may leak out through the vents in the cover when the pistons are pushed back.

On the left rear in the engine compartment, directly on the master brake cylinder, there is a reservoir with brake fluid (see fig.).



In a white transparent tank, the brake fluid level should be between the marks "M1N" And "MAX".

If the level has dropped, check the tightness of the brake system (read about it in the next section). In some models of cars, a special lamp in the dashboard gives a signal of a decrease in the liquid level.
