 PERFORMANCE ORDER

  1. Disunite the socket (8) of an electrical wiring of the sensor of level of brake fluid on the tank (9) brake fluids.
  2. Disconnect (11) brake lines (10) from GTTs.
  3. Disunite the socket (A7/7x2) of an electrical wiring of the electromagnetic valve / датчика-выключателя BAS otpuskaniye, and also I will corrode (A7/7x1) of the sensor of the course of a diaphragm of BAS.
  4. For the purpose of expansion of free space turn out clamping a bolt (14) of the plug of grounding of start of the engine from the external power supply.
  5. Having dumped depression by several squeezings of a pedal of a foot brake, disconnect the vacuum line (12) from the brake amplifier (A7/7), - estimate a condition of the rubber plug of fixing of the line, in case of need make its replacement.
  6. For the purpose of expansion of free space remove the control unit (C) and take him aside, without disconnecting any lines of communication.
  7. Uncover (1) under the dashboard at the left.
  8. Having turned to the left, pull and remove the sensor switch of stoplights (S9/1).
  9. Take the forelock (4) and remove a bolt (3) fastenings of a pusher to a pedal of a foot brake. Estimate a bolt condition, in case of need prepare a replaceable element, - the forelock is subject to replacement without fail.
  10. Give nuts (13), - all самоконтрящийся fixture is subject to replacement without fail.
  11. Remove the brake amplifier (A7/7) assembled from GTTs (11).
  12. Installation is made upside-down, - grease the landing surface of assembly before installation with sealant.
  13. In conclusion pump over the brake system (see the Section Pumping of the Brake System), examine its hydraulic path on existence of signs of development of leaks and make check of serviceability of functioning of stoplights.

BAS diaphragm course sensor

 PERFORMANCE ORDER

  1. Details of installation of the sensor of the course of a diaphragm of BAS are shown on an illustration of the Detail of installation of the brake amplifier (3 of 4)
  2. Several pressing a pedal of a foot brake dump residual depression in system of strengthening of brakes for the purpose of an otpuskaniye of a sealing ring of the sensor.

If the sealing ring is involved in assembly of the amplifier, the sensor should be replaced.

  1. For the purpose of expansion of free space turn out clamping a bolt (14) of the plug of grounding of start of the engine from the external power supply.
  2. Disunite the socket (A7/7x1).
  3. Having hooked the suitable tool, remove a lock ring (16b), - the ring is subject to replacement without fail.
  4. Having pulled, take the sensor (A7/7b1) from the landing nest.
  5. Installation is made upside-down, - track correctness of landing of sealing and lock rings. Before gas station of the sensor in a sealing ring moisten it in front with soap solution.
  6. Start the engine, several times squeeze out a pedal of a foot brake, then again switch off ignition and make sure of lack of signs of a podsasyvaniye of air via the sensor.
