8.7. The vacuum amplifier of brakes

Features of a design

Fig. 8.4. The vacuum amplifier: 1 – a flange of fastening of a tip; 2 – a rod; 3 – a returnable spring of a diaphragm; 4 – a sealing ring of a flange of the main cylinder; 5 – the main cylinder; 6 – an amplifier hairpin; 7 – the amplifier case; 8 – a diaphragm; 9 – a cover of the case of the amplifier; 10 – the piston; 11 – a protective cover of the case of the valve; 12 – a pusher; 13 – a returnable spring of a pusher; 14 – a valve spring; 15 – the valve; 16 – the rod buffer; 17 – the valve case; And – the vacuum chamber; In – the atmospheric chamber; With, D – channels


The device of the vacuum amplifier of brakes is shown on fig. 8.4.
The vacuum amplifier is combined enough, for its repair some skills and the special equipment are required, therefore at an amplifier exit out of operation («Check of an overall performance of the vacuum amplifier» see) replace it in gathering.

Removal and installation
It be required to you: keys «on 10», «on 13», «on 17».
1. Disconnect tips of wires from the gauge of level of a brake liquid.
2. Turn out a bolt of an arm of fastening of a tank of the hydraulic booster of a wheel...
3.... Take out a tank from an arm and take him aside.
4. Turn on two nuts of fastening of the main brake cylinder to the vacuum amplifier.
5. Without bending and without overwinding brake tubes, accurately take the main brake cylinder aside.
6. Holding the return valve, disconnect from it a hose.
7. From within salon remove lock скобу from a finger of a pedal of a brake.
8. Take out a finger of a pedal of a brake, having disconnected thereby a pusher of the vacuum amplifier from a pedal.
9. Turn away a nut of fastening of the vacuum amplifier.
10. Remove the vacuum amplifier.
11. Establish the vacuum amplifier in an order, the return to removal.
