So the issue with derailleur is now fixed. It wasn't installed properly. I checked the manual and installed the right way.
Regarding brakes I think this adapter will fix the issue: SM-MAF220P/PL
I adjusted another time, but it's seem the problem is in cassette, the biggest (50T) gear. The cassette has only 300km. Also, I added a new chain. When under pressure the chain wont sit properly. Maby a better cassette will fix this issue?
The rear brake is now ok. Front brake it's not ok. On first photo you see I removed washers. On second photo you can see upright original Shimano adapter, down is this adapter, that is installed. It's not the same dimensions. Still if I install original Shimano adapter there is still 2-3mm too...
I observed (and adjusted correctly) but the problem is under load that on granny gear the chain don't sit nicely to this gear. Maby the cassette is of bad quality.
Another issue is with granny gear. In other gears it's working normal. See video for issue. How can be fixed? Tnx
@temon10 did you have same issues?
Youtube video with issue: Granny gear not usable on Cyctrac EM5
@temon10 I have some problems with bike. Did you have same issues as I have.
The wearing on brake pads it's not even. This is very dangerous. This problem is present on frond and rear brake. How can I solve this issue?
