Prorolling of brake system
Prorolling of hydraulic system is made for the purpose of removal from it air getting to a path at performance of service of brake mechanisms, replacement of hydraulic lines or ГТЦ, and also at lowering below the minimum admissible value of level of a liquid in the tank of the main cylinder.
If air has got to system owing to falling of level of a liquid in tank GTTS, or at a detachment from ГТЦ brake lines, brake mechanisms of all four wheels are subject to prorolling. At a detachment of lines from any of supports / wheel cylinders will enough pump over only given concrete brake mechanism.
If the detachment of a brake line from the union located between ГТЦ and one of brake mechanisms was made, the given part of a brake contour is pumped over only.
The basic method of prorolling - 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 in the higher measure гигроскопичной and in due course absorbs in itself a lot of moisture that conducts to falling of a point of its boiling and, as consequence, to decrease in efficiency of braking. Besides, presence at hydraulic system of a moisture promotes the accelerated ageing of a material of flexible brake hoses.
Method of prorolling with use of the complete set with the return valve
As tells the name, the complete set for prorolling includes the piece of a hose equipped with the one-pass valve. The valve prevents possibility of return of a pushed out liquid back in system and will allow to make prorolling by forces of one person, - do not forget about necessity of tracing of level of a liquid for the tank of the main cylinder (level should not fall below mark MIN!).
Prorolling with use of compressed air
As a source of compressed air the spare wheel can be used, - it is preliminary necessary to dump pressure of its rating. Operate according to instructions applied on the complete set.
At use of the similar device it is required to release only the gate of prorolling and to wait the terminations of an exit from a path of air bubbles.
The main advantage of the given way consists that the big tank entering into the complete set with a hydraulic liquid does not suppose подсасывания air in a path during prorolling.
