9.3. Prorolling of a hydrodrive of brake system

Hydrodrive of brakes pump over for removal of air which has got there at filling by a liquid after its replacement or after repair of knots of a hydrodrive, connected with its depressurization.
Signs of presence of air in a hydrodrive:
– Increase in a course of a pedal, its "softness" by unitary pressing a pedal;
– Gradual reduction of a course of a pedal with simultaneous increase in its "rigidity" by repeated pressing a pedal.
Before hydrodrive prorolling it is necessary to find out and eliminate the depressurization reason.

GOOD ADVICE
If hydrodrive prorolling is connected with repair of any one contour and serviceability of other contour prorolling only a repaired contour is admissible is obviously known.

Actions at hydrodrive prorolling same, as well as at replacement of the brake liquid described in section 4 "Maintenance service" (Replacement of a working liquid in hydrodrives of brakes and coupling deenergizings »see«). Distinction consists only that criterion of end of prorolling of the working cylinder is the termination of an exit of vials of air from a hose, instead of occurrence of a fresh brake liquid.
