Super, got it! I had a small leak when I pressed the syringe hard. Tape was put on the thread, which sealed it 100%. It's cheaper than just the Avid kit and gives you the option to use any brand of brakes. Surely it will be useful in the future. Including brake pads. I think it's said, but it was a pleasant surprise for me. Lessons in Chinese. It's okay, I never read them until it's too late. I don't know exactly what petroleum jelly is for. I thought maybe to seal the syringe? I tried a bit but didn't completely remove the washer to make it work. I still got a "thump" in the vacuum during the "outgassing" of the liquid, but that happened in the tutorial videos, which I also watched, so I guess it's ok. My brakes are tight, both pistons are moving.
