So, KTM keeping me busy.

Bike has been standing for a week or so, took her out yesterday and the rear brake just goes all the way down with very little bite.
No leaks anywhere to be seen, fluid level looks good and was bled 4k km ago. Pads are also still good. 🤔

Been struggling for a month or so with a pedal that needs a few good pumps to actually brake well, but now it’s worse.

Will try to bleed again and see if it improves but my gut tells me the 12-year old master cylinder probably needs to be rebuilt. Anybody have part numbers for me, or some sage advice?
