Check of level of brake liquid

Continuous control

 PERFORMANCE ORDER

  1. In Audi A4 also control bulb on a control panel shows too low level of brake liquid, but nevertheless you should not refuse visual control:
  2. Open a cowl and wipe a tank with brake liquid a rag.
  3. Level of brake liquid should be in a transparent broad tank between marks of "mines" and "Max". In this case everything is all right.

Too low level of brake liquid?

If overlays of disk brakes are already a little erased, the tendency to fall of level of liquid is looked through up to the bottom mark; if they new, liquid level again exceeds the top mark. This absolutely normal phenomenon as at the erased slips put forward pistons of a disk brake are a little farther leave in cylinders of brake supports bigger volume which is filled with brake liquid. The situation becomes critical when in a tank level of brake liquid falls below a mark of "mines". As it does not evaporate and is not spent, that is a leakage place. Quickly find out the reason, the brake pedal yet did not refuse! Having added will be eyewash!
