Toyota RAV4>> Brake system>> Prorolling of a hydraulic drive of brakes
Prorolling of a hydraulic drive of brakes is necessary for removal of air which considerably reduces efficiency of braking. Air can get to a hydraulic drive owing to system depressurization at repair or replacement of a brake liquid. In air presence in a drive specify the increased course of a pedal of a brake and its softness. Before air removal check up tightness of all knots of a drive of brakes and their connections.
At partial separation of elements of hydraulic system and acceptance of corresponding precautions for prevention of the further loss of a liquid it is possible to pump over only a corresponding part of system.
Prorolling carry out together with the assistant.
Press a brake pedal some times at the idle engine to create in cavities of the vacuum amplifier the identical pressure close to atmospheric pressure.
Uncover a tank of brake system, add in it a brake liquid and establish a cover into place.
In the course of prorolling of brake system watch, that level of a brake liquid did not fall below the tank middle.

       THE PREVENTION
In the course of prorolling of brake system constantly watch presence of a brake liquid in a tank, without supposing an exposure of its bottom as thus air again will get to system.

Remove a dustproof cap from the union of prorolling of the working brake cylinder of a back right wheel, clear it and put on it the pure transparent hose which other end lower in the capacity partially filled with a brake liquid.
Sharply press a pedal of a brake of 3-5 times with an interval 2–3 with, and at the pressed pedal of a brake turn on on half of turn the prorolling union. Continuing to press a pedal, supersede a liquid being in system together with air through a hose in capacity. After the pedal will reach extreme bottom position and вытекание liquids through a hose will stop, wrap the prorolling union to the full. Repeat these operations, the air outlet from a hose will not stop yet.
Keeping a pedal in the pressed position, wrap the prorolling union against the stop and remove a hose from the prorolling union.
Wipe the union of prorolling and establish a protective cap.
Repeat these operations for other wheels in a following order:
– The left back wheel;
– The right forward wheel;
– The left forward wheel.
Pure brake liquid store in a tight vessel as it absorbs a moisture from air therefore the temperature of boiling of a liquid goes down and conditions for corrosion of details of brake system are created.
Check up level of a brake liquid in a compensatory tank of brake system and if necessary finish it to norm.
After the prorolling termination press against the stop a brake pedal, thus it should pass about half of course
