What do you think is good enough?http://www.amazon.de/…/279-4654463-7204052?…http://www.ebay.de/…/261478163314?… Short version: I realize that it will be difficult for people who have nothing to say about writing to the subject, but I try anyway, that’s why I get a little further in the first post. It’s about changing the brake fluid. In a commercial tuning booth. Both people are well trained and with a lot of experience in What they have done so far. Gifted mechanics stop. Focus are VAG vehicles. I myself am involved in the question only as a friend of the house and should also listen to the change of the brake fluid only occasionally. They are connected either with the conversions or it dive off and to people who want to switch to more powerful fluid than the factory filled up. About the 10 times a year this is the case. Tendency is currently however slightly rising The classic 2-man method with pumps, care for the diarrhea of the brake pedal and further tricks have now been explained as suboptimal It is tedious, time-consuming and the old soup can hardly be completely banished from the system with the new one, if you do not want to blow up the 2 times the amount. So a device should be used as a remedy. A 1000€ electric device is found for oversized. First of all this is already a proper investment, then this is again a large box the somewhere. It is also not as flexible if a different liquid is desired each time.
