M1200s recurrent rear brake failure, just me? 3rd time at Moto Rapido.

Hello Monster lovers. I need some help, please.

I bought a M1200s from new April 2017. In July 2017 it failed on a ride out. Moto Rápido said the manufacturer didn’t ‘bleed system prior to shipping and there was air in the system’ - odd but ok. Months later there was a recall on new ABS part - okkkeey.

Saturday I was on a slow riding course. First few exercises fine. Whilst doing u-turn no rear brake at all! I applied front brake and dropped the bike. Few scuffs and broken front brake leaver later. I am not happy!

Had anybody here had experience with rear brake failure on Monster 1200? Thanks.
