No rear brake again

[Martynbradley]

My 2020 bike had recall for new large master 18 month ago, thought it was getting a bit spongy again towards the end of last summer,but after 4 month storage,no back brake again,thought that Triumph had finally fixed it with recall, but now back to bleeding myself again.

It makes me wonder if the ABS cylinder is leaking thru. It may not have any external leaks but if the piston has a leak path, you'll get spongy brakes.

i think that the rear cyl is sucking air into the cyl.
the next time it sets try hanging a weight on to the break pedal.

In my opinion there is a design issue combined with manufacturing issue. You can rebuild all lines, ream and grind surfaces, use good quality washers.

I would think if it's a recall, Triumph is obligated to repair.

I think you you are spot on,dont think I will get anywhere taking to Triumph for them to bleed again and again.Think I will just bleed back brake myself every time I feel it getting a bit spongy as only 10 minute job.
