Indicator of the brake system

At inclusion of ignition the indicator of the brake system blinks for action check, at the working engine it has to go out.

If it blinks longer or flashes during the movement, it is necessary to check immediately the level of brake fluid (the head the Brake system). Perhaps, there was a depressurization and by that refusal of one brake contour that can also be noticed on the increased free wheeling of a pedal (in more detail about it in the head the Brake system).

Search of malfunctions of the indicator of the brake system


  1. Check of the indicator: see the text "Check of the indicator" in the section "Search of Malfunctions of the Indicator of Cooling Liquid".
  2. If the indicator blinks at the working engine in spite of the fact that the level of brake fluid in a tank costs above the mark "min", try to disconnect the plug from the tank level sensor with brake fluid.
  3. If the bulb dies away, so the sensor in a tank is faulty – to replace a tank.
