Hello forum! My ABS control unit is defective and, as I can see from the outside, has been repaired (case is pretty messed up). Unfortunately, the lower screw was so screwed up that I gave up the control unit after an hour. There are probably only two ways to get there: 1. To completely destroy the control unit, buy again for a lot of money and have the risk to destroy even more. 2. To expand the hydraulic unit with control unit The advantage: maybe the control unit can be saved and money saved. However, I have not yet found any useful information for venting the hydraulics and braking system after installation. I have already vented many brakes and otherwise also abundant, screwdriver experience, so that there is no lack of craftsmanship and suitable tools. Only with ABS I do not have the experience, whether it is self-exposed, white l it is very close to the brake fluid tank, or whether it is aired when the brakes are ventilated. I would be really grateful for relevant information.
