Checking the brake fluid level
The brake fluid level must always be between the marks «max» and «Min».
A slight drop in the brake fluid level occurs during the operation of the vehicle due to wear of the brake linings and automatic adjustment of the brake pads. This is quite normal.
If the level of the brake fluid has dropped noticeably in a short time or has dropped below the mark «Min», the reason may be a violation of the tightness of the brake system. Too low level of a brake liquid in a tank is signaled by the control lamp of brake system.
Brake fluid change
Brake fluid absorbs moisture. Therefore, during the operation of the car, the brake fluid takes a certain amount of water from the surrounding air.
Too much water in the brake fluid can eventually cause corrosion of parts in the service brake system. In addition, this significantly reduces the boiling point of the brake fluid.
Attention: If the brake fluid is very old, vapor bubbles may form in the system when the service brake system is heavily loaded. This has a negative effect on the efficiency of the service brake system and thus on traffic safety.
