I forgot to mention that the failure of the fixed lights appeasr when purging the deposits of the handlebar and the one in the rear wheel. that is to say, when purging from the 6 purgers that there are in the servo. I have started purging those of the front and rear brake calipers and since this has to be done with the ignition on, I have seen that at that moment the lights did not fail. At the end of purging the 6 purgers is when I hit the contact, the fault has appeared. Brakes work OK
I have good power assist using either front lever and rear pedal. The rear brake light work OK Tomorrow i will try the ABS on a slippery surface and see what happens.
