Hello together, I had to change the front brake hoses with my vehicle, because the old porous and barely permeable ones were. Then I logically wanted to vent the brake and with the help of a cheap ventilator, as you get it at ebay, amazon and Co.. Unfortunately, the device did not put up any pressure, then I pumped the pedal, which had the same effect in the end. But after the first test drive I had the impression, that the braking effect was already better and wanted to air out a second time. With the rear brake calipers this worked immediately, but at the front then directly air bubbles came with and more and more air and finally only air. It looked from the outside at least as if brake fluid had flowed continuously into the container. But then I screwed up the container and found that it was almost empty. I finally filled up by hand and the chi ng-thing thrown into the corner and wanted to try it without, but no matter how often I pump over the pedal, there is nothing, neither left nor right. But the container is still full, so there seems to be nothing to follow. What now, do I have so much air in the system that no pressure can be built up at all? If so, how can I get the (possibly with home supplies) out again? Plan B would be driving to the next workshop, but they have a. no time and are b. lying on the mountain. At least in the rear circuit there would have to be still liquid and thus also brake pressure, so a short drive should be possible within the place, I would still have to have the hand brake. But what irritates me a little is a warning in the workshop manual: it says, you should not let the servo pump run for more than 2 minutes at a time during the venting. Now I wonder, what happens to the servo pump, if I drive with air in the system, the then also hot? Supposedly one drives with a defective brake hose and one of the circuits runs empty, as the pump should not give up the spirit? Thanks and greetings Olli
