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 an ottormozhenny condition in both cavities of the amplifier divided by a diaphragm, depression is supported. When braking in a back cavity of the amplifier air from the atmosphere which has additional power impact on a diaphragm and the piston of the main brake cylinder is brought. After an otpuskaniye of a brake pedal the back cavity of the amplifier is disconnected from the atmosphere and incorporates via the return valve to the inlet pipeline of the engine – a depression source.

To check

PERFORMANCE ORDER

At the idle engine several times to press a brake pedal for razryazheniye reduction in the amplifier. Then to press and hold 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 down.
If the pedal remains on a place, the possible reason is malfunction of vacuum system: return valve, hose etc. To check vacuum system.

To remove or disconnect

Dismantle of a clamp of the plug

AND. SCREW-DRIVER

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

Dismantle of the adjusting plug

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

PERFORMANCE ORDER

1. The main brake cylinder from the case of the amplifier. To unscrew nuts and to shift the cylinder a little forward. Not to disconnect brake pipelines from the main brake cylinder.

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

3. A vacuum hose from the case of the amplifier.

4. Stoplight switch.

5. 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 amplifier of a steering to unscrew nuts of fastening of an arm of a pedal to the forward panel.
On the car with the amplifier of a steering to unscrew 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 up.

9. An arm from the case of the amplifier.

10. Protective cover 11с amplifier.

11. A clamp 8 from the plug 7.

12. Pusher 10.

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

14. To unscrew a nut 9.

To establish or attach

Measurement of length of a pusher

And. DISTANCE of 278,5 mm
CENTURY. A OPENING UNDER THE FORK FINGER

6. CASE OF THE VACUUM AMPLIFIER
10. 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 opening of a fork of a pusher should be equal 278,5 mm (see fig. Measurement of length of a pusher).

5. Protective cover 11.

6. An arm on the case of the amplifier. 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 opening of a fork of a pusher and a brake pedal.

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

12. Stoplight switch.
