7.3.1. Air removal with use of a set of pumping under pressure
GENERAL INFORMATION

For air removal from hydraulic system it is necessary to use the special equipment working from external pressure (the beefy chamber of a spare wheel). After connection of the tight chamber with brake liquid to a popolnitelny tank of brake system removal of air consists in liquid plum via the pumping union on the working cylinder of coupling until following liquid will not leave without air vials.

Prevention

Volkswagen recommends to use the compressed air submitted under the pressure of no more than 2,5 bar.

When using this method with a big tank with liquid additional protection of hydraulic system of coupling against possible hit of air is provided during pumping.

PERFORMANCE ORDER
1. According to the instruction connect the adaptation for air removal under pressure to a popolnitelny tank of brake system.
2. Put on a transparent hose (for example VAG 1238 In/3) the union of pumping of the working cylinder of coupling (In) which second end lower in the glass vessel which has been partially filled with brake liquid.
3. Unscrew the pumping union on a half of a turn and allow liquid to flow down in a glass vessel until it will not leave without air vials.
4. After air removal from hydraulic system of coupling screw up the pumping union, remove from it a hose and remove the adaptation from a popolnitelny tank.
5. Clear the pumping union of brake liquid and establish on it a dustproof cap.
6. Check level of brake liquid in a popolnitelny tank and, if necessary, add brake liquid.
