Use of the complete set of prorolling under pressure demands giving to it of the compressed air for what it is possible to use the beefy tyre of a spare wheel. Reduce pressure in the tyre to the size specified in the maintenance instruction of the complete set.
The prevention Opel recommends to use the compressed air submitted under the pressure of no more than 2 bar.
At prorolling by this method the considerable quantity of a liquid for hydrosystem is necessary to prevent air hit in the main brake cylinder in the course of prorolling that often occurs, if liquid level in a tank is not supported.
Prorolling by pressure is especially effective, when the system is difficult for prorolling or when full prorolling of system is spent during usual replacement of a brake liquid.
| PERFORMANCE ORDER |
| 1. Connect the filled brake liquid the container to пополнительному to a tank of the main brake cylinder. |
| 2. Prorolling process begins after unscrewing of the union of prorolling on half of turn. |
| 3. After when will stop вытекание a brake liquid with vials of air and the pure brake liquid will follow only, screw up the prorolling union against the stop. |
