407 brake system malfunction

brake system malfunction for the first time 205 model 407 dynmc package and not working can you help me if my car has ever been encountered with such a problem before

Get well soon. Watch the video below might help. The sockets are very oxidized. Maybe your question is the same. Let's see

We connected the vehicle to the computer, says 2 brake contactor failure, we changed the abs, again giving the same fault, we cleaned the sockets, we changed the fuses again, giving the same problem. ..

Called the brake contactor. Brake sensor I guess. It may have a short circuit. Has anything been done with the brake or discs before this failure?
