6. THE CASE OF THE VACUUM AMPLIFIER
13. THE NUT OF FASTENING OF THE VACUUM HOSE TO THE INLET PIPELINE OF THE ENGINE

On the car the vacuum amplifier of brakes with one dividing diaphragm is established. In отторможенном a condition in both cavities of the amplifier divided by a diaphragm, depression is supported. At braking in a back cavity of the amplifier air from atmosphere which has additional power influence on a diaphragm and the piston of the main brake cylinder is brought. After отпускания a brake pedal the back cavity of the amplifier is disconnected from atmosphere and incorporates through the return valve to the inlet pipeline of the engine – a depression source.

To check up

PERFORMANCE ORDER

At the idle engine some times to press a brake pedal for reduction разряжения in the amplifier. Then to press and keep a brake pedal of the pressed. To start the Engine.
The vacuum amplifier is serviceable, if the brake pedal receives at engine start additional moving downwards.
If the pedal remains on a place, the possible reason is malfunction of vacuum system: the return valve, a hose etc. To check up vacuum system.

To remove or disconnect

Dismantle of a clamp of the plug

AND. THE SCREW-DRIVER

7. THE ADJUSTING PLUG OF THE PUSHER OF THE PEDAL
8. THE CLAMP OF THE ADJUSTING PLUG

Dismantle of the adjusting plug

7. THE ADJUSTING PLUG OF THE PUSHER OF THE PEDAL
9. THE NUT

PERFORMANCE ORDER

1. The main brake cylinder from the amplifier case. To turn away a nut and to shift the cylinder a little forward. Not to disconnect brake pipelines from the main brake cylinder.

2. A nut of 13 fastenings of a vacuum hose to the inlet pipeline.

3. A vacuum hose from the amplifier case.

4. The stoplight switch.

5. A spring of a brake pedal.

6. To remove a stopper and to take out a finger of a pusher of a brake pedal.

7. On the car without the steering amplifier to turn on nuts of fastening of an arm of a pedal to the forward panel.
On the car with the steering amplifier to turn on the bottom fixing screw located behind hydraulic pipelines.

8. The case of the amplifier and an arm from the forward panel of the Body. A few to incline the case of the amplifier and to take out upwards.

9. An arm from the amplifier case.

10. A protective cover 11с the amplifier.

11. A clamp 8 from the plug 7.

12. A pusher 10.

13. To turn on and remove the plug 7 from a piston pusher.

14. To turn away a nut 9.

To establish or attach

Measurement of length of a pusher

And. DISTANCE of 278,5 mm
CENTURY THE APERTURE UNDER THE PLUG FINGER

6. THE CASE OF THE VACUUM AMPLIFIER
10. THE PUSHER OF THE BRAKE PEDAL

PERFORMANCE ORDER

1. To establish the new amplifier in a vice. To use safety linings.

2. To screw a nut 9, to establish the plug 7 on a piston pusher.

3. To insert a pusher of 10 pedals into the plug 7 and to establish a clamp 8.

4. To adjust position of the adjusting plug. The distance from the case of the amplifier to an axis of an aperture of a plug of a pusher should be equal 278,5 mm (fig. Measurement of length of a pusher see).

5. A protective cover 11.

6. An arm on the amplifier case. To tighten nuts the moment of 22 Nanometers.

7. The amplifier with an arm on a forward board. To tighten nuts the moment of 22 Nanometers.

8. The main brake cylinder to the amplifier. To tighten nuts the moment of 18 Nanometers.

9. To attach a vacuum hose to the amplifier and the inlet pipeline. To tighten a nut of fastening of a hose to the inlet pipeline the moment of 15 Nanometers.

10. To insert a finger into an aperture of a plug of a pusher and a brake pedal.

11. To establish a stopper of a finger and a spring of a brake pedal.

12. The stoplight switch.
