Constant check

 PERFORMANCE ORDER

    About too low level of a brake liquid in Audi 80 you though will be warned by the indicator on a control panel, but nevertheless it is impossible to refuse the visual control: To open a cowl and if necessary to clear a rag a receiver of a brake liquid. Level of a brake liquid should be in a transparent tank between marks min and max. In this case everything is all right.

Too low level of a liquid?

If overlays of the disk brake mechanism have already a little worn out, liquid level is most likely near the bottom mark; if they new most likely it will be above. It is absolutely normal, because the pistons of the disk brake mechanism acting at worn out overlays already a few further, leave in cylinders of supports больший volume which is filled with a brake liquid.

The critical moment comes, if level of a brake liquid in a tank falls below the minimum mark. As the brake liquid does not evaporate and is not spent, it means that in system somewhere there is not tight place. Therefore it is necessary to search urgently for the reason and a leaking place, without waiting, while the brake pedal will leave in emptiness. Simply to add liquids in a tank is a self-deception!
