11:13. Replacement of brake highways

Brake hose of a forward axis

Brake hose of a back axis


1. Raise the car.
2. Remove a cap nut from the brake pipeline.

At the same time brake fluid follows. Close a suitable stopper an element of connection of a brake wire in the direction of the main brake cylinder that brake fluid completely did not flow out from a tank. After repeated installation air has to be removed from the brake system. The special device therefore address to repair shop is necessary for removal of air from a brake of cars with ASR. Collect brake fluid in the vessels intended only for it.

3. Whenever possible lay the new pipeline of brake fluid on the same place.
4. At connection of the pipeline moisten a conic surface of a prileganiye with several drops brake, liquids and tighten with the moment 15 N. of m.
5. Unscrew the brake pipeline (5) or (6) from a brake hose (51). Use an open laid on wrench 9х11, holding a brake hose with Rozhkov a wrench. Close an element of connection a stopper.
6. Disconnect the holder of a brake hose (51a).
7. Unscrew a brake hose (51) from a support.


1. To establish only the brake hoses allowed for use by firm.
2. Tighten a brake hose on a support with m 20 N.' moment.
3. Screw a brake hose on the brake pipeline with m 15 N.' moment. The brake hose at installation should not be overwound. Fix a lock washer at the holder by a dodecahedron. So insert a brake hose into a lock washer that it at full turn of the operated wheels to the left or to the right did not hit against anything. 4 – the brake pipeline, 13 – a cap bolt, 59 – the holder of a brake hose.

After repair the holder (52) can be bent. Carefully correct it since even minor change of position of the holder on the basis of a frame can change passing of a brake hose therefore it can be wiped, adjoining to other parts of the car.

4. Pump over brakes.

Carry out safety control:

      – whether all brake pipelines / hoses are tightened;
      – whether pumping screws are tightened;
      – whether as it should be level of brake fluid;
      – at the working engine make tightness control. For this purpose press a brake pedal with effort from 200 to 300 N (20–30 kg) within about 10 seconds. The pedal should not move. Check tightness of all connections.

5. In conclusion make several braking on the quiet street.

Control of the amplifier of braking

Control of the amplifier of braking is made in case for achievement of sufficient effect of braking it is necessary to make too big effort to braking pedals.

1. At the stopped engine of at least 5 times strongly press a brake pedal, then start the engine at the loaded brake pedal. At the same time the brake pedal has to move noticeably under a leg.
2. Otherwise unscrew a depression hose from the amplifier of braking, start the engine. Having put fingers to the end of a hose of vacuum, check vacuum availability.
3. If there is no vacuum, check a hose for tightness and damages, in case of need replace it. Strong tighten all collars of hoses.
4. If vacuum is, measure it, in case of need, replace the amplifier of braking (work in repair shop).


Pedal / forward drive of a cable

12i. Protective cover
12. Automatic equalizer of length of a cable
94. Ottyazhny spring
85. Forward brake cable
75. Mobile level
84 century. Coupling ring
043. Razzhimny device
71. Case
73. Six-sided bolts
S12. Shtekker of the switch of the parking brake
80. Spring clip
79. Draft
71. Pedal
94. Ottyazhny spring

Removal of a brake cable

1. Remove a back seat.
2. Remove a protective cover (12i).
3. Tighten the automatic equalizer of length of a cable (12). For this purpose turn a wrench with an internal hexagon a crank (g) approximately on 1/2 turns to the right and at the same time advance it in longitudinal to a vent back until it is recorded in the case of a spring (a) in a spring clip (g). (e – the lever of the equalizer, f – the intermediate lever, 93 – a safety pin.)
4. Unhook an ottyazhny spring (94).
5. Disconnect a brake cable (85) from a mobile level on a pedal, squeeze together a coupling ring (85v) with the razzhimny device (043) and extend a cable. If is not present at the disposal of the razzhimny device (the special tool), the cable can be taken, having removed a coupling ring. At installation insert a coupling ring into a cable flute.

Removal of the device of a pedal

1. Remove the case from the device of a pedal and unscrew six-sided bolts (72).
2. Disconnect the plug of the switch of control of the parking brake (S12). For this purpose it is necessary to raise the pedal device a little.
3. Remove a spring clip.
4. Disconnect a cable of manual adjustment (79) and take the pedal device.


1. Installation is made as it should be, the return to dismantling of the device of a pedal.
2. Before installation of a protective cover to weaken the cable length equalizer. For this purpose raise the screw-driver a spring clip. After that the equalizer of length of a cable is installed automatically.
3. Several times put the parking brake in action, at the same time it is adjusted spontaneously.
