| - Disconnect the connector (8) electrical brake fluid level in the reservoir (9) brake fluid.
- Disconnect from the GTZ (11) brake line (10).
- Disconnect the connector (A7 / 7x2) electrical solenoid valve / gauge-switch is released, BAS, and the connector (A7 / 7x1) stroke sensor diaphragm BAS.
- To expand the space loosen the clamping screw (14) ground terminal starting the engine from an external power source.
- Throwing a vacuum by a few push-pedal brakes, disconnect the brake booster (A7 / 7) vacuum line (12), - evaluate the state of the rubber plug fixing lines, in case of need make replacement.
- To expand the space, remove the control unit (C) and move it to the side without disconnecting any lines of communication.
- Remove the cover (1) to the left under the dashboard.
- Turning to the left, pull and remove the gauge-switch of stoplights (S9 / 1).
- Remove the cotter pin (4) and remove the bolt (3) securing the pushrod to the brake pedal. Assess the bolt, if necessary, prepare a removable element - pin must be replaced without fail.
- Give nuts (13), - the whole self-locking fasteners be replaced without fail.
- Remove the brake booster (A7 / 7), complete with the GTZ (11).
- Installation is in the reverse order - the seat surface of the assembly prior to installation with sealant.
- In summary pump over brake system (see. Section Bleeding brake system), inspect the hydraulic path for signs of leaks and make check of serviceability of functioning of brake lights.

BAS diaphragm travel sensor | - Details of the sensor diaphragm stroke BAS shown in the illustration details the installation of the brake booster (3 of 4)
- A few taps on the brake pedal reset the residual vacuum in the brake pressure for the purpose of releasing the sealing ring sensor.
 | If the O-ring will be drawn into the amplifier assembly, the sensor must be replaced. |
- To expand the space loosen the clamping screw (14) ground terminal starting the engine from an external power source.
- Disconnect the connector (A7 / 7x1).
- Having hooked a suitable tool, remove the retaining ring (16b), - the ring is subject to replacement without fail.
- Pull, pull the sensor (A7 / 7b1) from its landing slot.
- Installation is in the reverse order - track correctness of landing of a sealing and locking rings. Before filling the sensor O-ring soak it in front of a soap solution.
- Start the engine several times depress the foot brake, then again turn the ignition off and check for signs of air suction through the sensor.
