The article presents native and foreign bench-top
and board methods to test the automobile break
systems. One can find information about some
native trailer-break stands. We have analyzed their
advantages and drawbacks such as low information
capacity, high diagnostics processing time, low
quality of regulation and maintenance operations
due to big influence of the operator’s experience,
his knowledge and individual characteristics, and
great instability of manual test modes on the results
of the investigations. To remove these shortcomings
they have had some experiments at MADI in order
to develop the module to the brake qualities stand.
When using it one can have automatic diagnoses
and flow chart is presented in the article. Due to the
existing vehicles’ state inspection mode and
diagnostic means in our country there appeared new
stands for brakes control. One can attribute to these
devices a range of brake qualities stands developed
and produced at Novgorod plant GARO. These are
STS-3, STS-10 and STO series stands for cars,
trucks, buses and micro-buses. The article also
presents some foreign stands used in Russia such as
universal brake stands STM by META firm, the
break stand IW7 Eurosystem by MAHARUSSIA
firm. We have presented in the article the results of
the analysis of simple and complicated board means
of diagnosis as “Eftor-2”, “Effect”
The article presents a technical diagnostics of a car as a complex of goals and tasks connected with
trouble-shooting of mechanisms and systems in
order to eliminate them. We have considered the
stages of computer diagnostics of different
automobile systems such as diagnosing the engine,
the brake system, steering and suspension. We have
analyzed their components, the ways of troubleshooting
and elimination recommendations. The
article presents the main troubles transferred from
the electronic control unit. The article also presents
the stages of diagnosing the engine including
external examination, listening to abnormal noises,
checking the operating fluids and the engine
management system, diagnosing the basic engine
systems and checking the cylinders being filled.
The article contains the list of main troubles and
their reasons. One can also see diagnosing the brake
system, its defects and remedies. The article
presents diagnostics and repair of the suspender and
graphics describing the check of the dismantled
shock strut at the stand and tests of the shock strut
without being dismantled. We have analyzed
computer diagnostics and the problems it solves
