As a rule, the steering mechanism with the hydraulic booster possesses high reliability and does not demand difficult service at car operation. Even in default the amplifier pump, movement on the car can be continued, though for поворачивания a steering wheel in this case it is required to put much more efforts, than even on the car without the hydraulic booster.
The reason of full refusal of the hydraulic booster is breakage приводного a pump belt more often. Regularly check a belt condition – it can be worn out or poorly tense. One of signs of a weak tension of a belt is return occurrence (a return push) on a steering wheel. Usually it is the most appreciable at трогании than the car from a place when wheels are turned to the full.
Support up to the mark quantity of a liquid in an amplifier tank. If necessary add a liquid only specified in a management on mark service. Consider that a liquid intended for АКПП, it is possible to use not for all hydraulic boosters of a steering. On sale there are many different marks of liquids. The improper liquid can spoil all epiploons in system.
As the liquid is used not only as a working body of hydrosystem but also as lubricant, it is very important that its level did not fall below norm, differently the pump can fail. Watch also cleanliness of a liquid. The dirty or delayed liquid quickly will destroy the pump and the consolidations of hydrosystem located on реечном the mechanism that will demand then expensive repair. Liquid replacement is required seldom. If you wish to merge a liquid, it is necessary to open a cover of a broad tank, to disconnect one of pipelines of system and some times to turn a steering wheel here and there for expression of a liquid from hydrosystem. The special aperture for liquid plum usually is absent. Refuelling of a new liquid is made through a broad tank. As a rule, thus in hydrosystem the air stoppers breaking its working capacity are formed. They should be removed. Most easier to make it as follows. Start the engine, open a cover of a broad tank and pump over system, turning a wheel some times from one extreme position in another. On a measure прокачивания hydrosystems liquid level in a tank will go down. Repeat this procedure until it is not stabilised. After that add a liquid to demanded level and close a cover, preliminary having checked up, whether the ventilating aperture (if it is available) is littered in it.
The most frequent malfunction of hydraulic boosters is the liquid leak. With such defect cars usually do not manage to pass checkup. At some old hydrosystems small infiltration of a liquid through bearings, shaft, etc. as they cannot be made completely tight was supposed. Regularly examine system knots from different directions for timely detection possible подтеканий from pipelines and unions, and also from not hardly fixed pipelines and other details.
Find out, whether and hoses tubes rub against a chassis and suspension bracket detail. Malfunction of a hydrowire can lead to liquid break through covers. Making check, turn a steering wheel from one extreme position in another. Small leaks can be eliminated, having entered into a liquid special герметизирующие additives which are available on sale. However it will be only a short-term measure. In case of malfunction of the pump it can be repaired, having taken advantage of the repair complete set of new epiploons. Replacement of epiploons a little that will correct, if the pump is worn strongly out.
For those who likes to do all independently, repair of the pump will not present great difficulties. However before to establish the repaired pump on the car, it is desirable to check up it at the stand. If you suspect that the pump is worn out, address to the expert in hydraulic boosters that it has checked up its working pressure and has correctly defined malfunction. Generally speaking, numerous advantages of a wheel with the hydraulic booster many times over outweigh the problems created by its possible malfunctions. Costs after you have done a bit of travelling on the car with modern system, to change on the car which does not have the hydraulic booster of steering system, and you immediately "will feel a difference".
