12.10.3. Pumping – use of a set of pumping under pressure


When pumping by this method a large amount of liquid for hydrosystem is necessary to prevent air hit in the main brake cylinder in the course of pumping that often occurs, if liquid level in a tank is not supported.

Pumping by pressure is especially effective, when the system is difficult for pumping or when complete pumping of system is spent during usual replacement of brake liquid.

1. Use of a set of pumping under pressure demands giving to it the compressed air for what it is possible to use the beefy tire of a spare wheel. Reduce pressure in the tire to the size specified in the maintenance instruction of a set.


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

2. Connect the filled brake liquid the container to a popolnitelny tank of the main brake cylinder.
3. Process of pumping begins after unscrewing of the union of pumping on a turn half.
4. After when the effluence of brake liquid with vials of air will stop and only pure brake liquid will follow, screw up the pumping union against the stop.
