Pumping of brake system
Pumping of hydraulic system is made for the purpose of removal from it of the air getting to a path at performance of service of brake mechanisms, replacement of hydraulic lines or GTTs, and also when lowering below the minimum admissible value of level of liquid in the tank of the main cylinder.
If air got to system owing to falling of level of liquid in the GTTs tank, or at a detachment from GTTs of brake lines, brake mechanisms of all four wheels are subject to pumping. At a detachment of lines from any of supports / wheel cylinders will enough pump over only this concrete brake mechanism.
If the detachment of the brake line from the union located between GTTs and one of brake mechanisms was made, only this part of a brake contour is pumped over.
The main method of pumping - is required the help of the assistant
At all do not add in the tank the brake liquid which was in the use, - it is hygroscopic in the highest measure and over time absorbs in itself a lot of moisture that conducts to falling of a point of its boiling and, as a result, to decrease in efficiency of braking. Besides, presence at hydraulic system of moisture promotes the accelerated aging of a material of flexible brake hoses.
Pumping method with set use with the return valve
As tells the name, the piece of a hose equipped with the one-pass valve enters into a set for pumping. The valve prevents possibility of return of pushed-out liquid back in system and will allow to make pumping by strengths of one person, - do not forget about need of tracking of level of liquid for the tank of the main cylinder (level should not fall below MIN mark!).
Pumping with use of the compressed air
As a source of the compressed air the spare wheel can be used, - previously it is necessary to dump pressure of its rating. Act according to instructions enclosed to a set.
When using the similar device it is required to release only the gate of pumping and to wait the exit terminations from a path of air bubbles.
The main advantage of this way is that the big tank entering into a set with hydraulic liquid is not allowed by an air podsasyvaniya to the highway during pumping.
