But if there is no problem with the front brake, then the front brake will not be happy with the front brake, but the front brake will not be happy with the front brake, which was in front of the front brake hose and front brake hose change (and more) with ABS still closed by the previous owner, is too lax and has too much difference. I have changed the brake cheeks and front brake hoses, had to fry 1x each axle and had to run the brake fluid empty. All connections are tight, it has been repeatedly with the device and pedal ventilated and there are no more bubbles to be found, but now it is hissing my BKV or HBZ when braking. Do I still have air in the system, and how can I get that out? Does that hang with the clutch hydraulics together? (coupping feeling is unchanged) Did I have my BKV or HBZ and how did I test it? Only indication are the brake pads installed by the front brake owner, but the last side would not have been happy with the brake plate.
