GENERAL INFORMATION

Main brake cylinder and vacuum amplifier of brakes

1–socket of the sensor of level of brake liquid;
2–tubes of brake system;
3–nut;
4–main brake cylinder;
5–sealing ring of round section.

Removal

PERFORMANCE ORDER

1. Disconnect the electric socket from the sensor of level of brake liquid.

2. A key ОК130 430 019 unscrew brake tubes from the main brake cylinder and the ABS control unit and close them plastic jams for an exception of hit of dirt in them.
3. Turn out two nuts of fastening of the main brake cylinder.

4. Remove the main brake cylinder from hairpins of the vacuum amplifier of brakes.

Installation

PERFORMANCE ORDER
1. At installation of the new main brake cylinder adjust the provision of a pusher of the vacuum amplifier of brakes as follows:

      – establish the special adaptation ОК370 430 018 in the main brake cylinder. Turn an adjusting bolt while it will not be established in a pusher opening in the piston;
      – the vacuum pump create depression of 500 mm Hg in the vacuum amplifier of brakes;
      – overturn the special adaptation ОК370 430 018 and establish it in the vacuum amplifier of brakes;
      – measure a gap between an end face of the adaptation ОК370 430 018 and a pusher of the vacuum amplifier of brakes.

If the gap is not equal 0 mm, weaken a lock-nut of a pusher and rotating a pusher execute adjustment.

Prevention

After carrying out adjustment and installation of the main brake cylinder on the vacuum amplifier of brakes, the gap between a pusher and the piston should correspond given in the table.


The vacuum enclosed to the vacuum amplifier of brakes, mm Hg.
Gap between a pusher and the piston, mm
0
0,4–0,6
500
0,1–0,4

2. Establish the main brake cylinder on the vacuum amplifier of brakes and screw two nuts. Tighten two nuts of fastening of the main brake cylinder.

Inhaling moment: 9,81–15,7 N • m

3. Tighten nuts of fastening of tubes of brake system.

Inhaling moment: 13–22 N • m

4. Connect the socket of the sensor of level of brake liquid.
5. Remove air from a hydraulic contour of brake system.
6. Connect a wire to the negative plug of the storage battery.
