Evening all

I’m having an issue with the rear brake on my 1200GSA. Primarily in that I don’t have one. I suddenly lost all pressure at the pedal while on a ride. I’ve bled them and pressure bled them and there is fluid in the M/C and at the caliper, but absolutely no pressure at pedal or caliper. Not getting anything at all. Any ideas?

Suddenly?

I've had 3 LCs and they've all had issues with rear brake performance

Pretty much what I’m thinking, unfortunately. I’m going to pop into my local indie shop tomorrow and see if they can have another go at bleeding it in case I’ve fucked it up. Otherwise, I know what I’m getting for Xmas…

I just hope Santa brings you some fresh vaseline for your visit to the dealership. When my rear master cylinder started leaking on my hexhead, the cost of a replacement BMW branded Brembo item was stupid so I got a warranted used one off a low-miler from motorworks.
