11.2. Prorolling of hydraulic brake system

THE GENERAL DATA

---

The prevention

The brake liquid used in hydraulic system of brakes, is poisonous, therefore at its hit on a skin it is necessary to wash out immediately this place a plentiful quantity of water. If the liquid has got to eyes or in an organism, it is necessary to address immediately to the doctor. Some liquids have property easily to ignite and can light up even from contact to hot knots of the car. Besides, the liquid used in hydraulic system of brakes, dissolves a paint and plastic, therefore at liquid hit on a paint and varnish covering of the car wash out its plentiful quantity of water. Also this liquid гигроскопична, i.e. absorbs a moisture from air and consequently a liquid, stored in open ware, it is not recommended to use long time.

Prorolling of hydraulic system of brakes is necessary for removal of air which considerably reduces efficiency of braking. Air can get to hydraulic system owing to system depressurization at repair, replacement of separate knots or a brake liquid. In air presence in a drive specifies 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.

The prevention

Never use a brake liquid repeatedly.

At performance of operation of prorolling of brake system let's to level of a brake liquid fall below the tank middle.

If the brake liquid has left system because of leak in system, find the reason and eliminate leak before the further actions.

If the hydraulic system was separated partially and corresponding precautions have been accepted to prevent the further loss of a liquid, it is possible to pump over only a system part.

Prorolling can be carried out with the assistant or it is independent, the complete set of prorolling of brake system. Always operate under the instruction. It is recommended to use the complete set everywhere, where probably as it very much simplifies prorolling procedure. If the complete set for prorolling is not present, it is necessary to be reserved by pure capacity and a transparent plastic tube of the corresponding length which should put on densely on the prorolling union. The help of other person thus is required.

Sequence of prorolling

If it was made only partial рассоединение hydraulic brake system and corresponding precautions were observed enough to pump over only this part of system. If prorolling of all hydraulic system of brakes is made, prorolling carry out in the following sequence.

Models without ABS:

  – The left back;
  – The right forward;
  – The right back;
  – The left forward.

Models with ABS:

  – The left forward;
  – The right forward;
  – The left back;
  – The right back.
