Technical characteristics


Control bulb of the parking brake

At the switched-on parking brake the switch closes connection with weight. Thanks to it the control bulb can light up as at the included ignition it is supplied with tension through its other contact. At the released parking brake it dies away.

Search of malfunctions


  1. The bulb does not burn at the switched-on emergency brake: check a safety lock (the head the Electrotechnical equipment).
  2. Dismantle the glow lamp and check it (the beginning of the head).
  3. If it did not result in success, then bare the switch behind the lever of the parking brake, having dismantled a back part of the average console.
  4. Disconnect a wire on the switch (behind near the emergency brake) and apply the socket to the bared metal.
  5. If the bulb burns, the switch is faulty
  6. The bulb does not die away at the switched-off parking brake: remove a wire on the switch of the emergency brake as it is described above, but leave the socket hanging.
  7. If the bulb does not burn any more, then faulty/are wrong the switch was mounted.
  8. But if it continues to burn, then the wire is wiped and will close on weight.

The switch (2) of a control bulb of the parking brake is precisely behind its lever (1 – here it is shown at the dismantled average console).
