I let my 2015 Full Throttle sit for a year. The battery died, 5 years old, that's expected. Even though the tender was still green like it was OK.
So when I changed out the battery, the bike started right up, no problemo. But when I first turned on the key, the speedo didn't do the sequence like usual. It lit up (the speedo) and made a funny noise from under the seat I have never heard before. THEN it did the usual start up sequence. I started to ride, then the rear brake pedal went all the way down to the bottom! No rear brake! No pressure, no nothing!
Has anyone had this happen? Is the ABS unit messed up? I don't know. There aren't any Ducati dealers around here anymore. (they got closed - Seattle area). I'm screwed. I'm not a mechanic. Any advise??
Thanks very much!

Extremely common Ducati issue. My wifes Monster did exactly the same thing when left unused for a while. the shop knew all about it. I have heard of plenty of others with the issue as well.
Somewhere along the line air bleeds into the rear brake system when it sits and we all know what happens when air gets into the brake system.
I tried a fluid change on the Monster but couldn't get it working but I had nothing other than basic tools. The the shop fixed it easy with their gear.
The system is pretty straightforward there may not be a Ducati shop handy but any motorcycle repair place or even (car) brake repair place should be able to sort it easy enough. There are no special Ducati parts in the brake system.

Hi K1W1,

Thank you for your kind advice. Talking with a couple others, seems like it needs to get beld out. I know the basics of it, but have never done it myself. I was also wondering about the fact that there is an ABS unit in the line. Would that interfere with bleeding the brake line? When I turned on the key (very first time), the speedo lit up, but not like normal. No numbers, just light. Then was when I heard the weird noise from under the seat. A noise I have never heard before. I assume that maybe it was the ABS unit doing something?

That's why I hate bells and whistles. More stuff to break!

I hate it! My bike is all nice and clean. Got a new battery. My knee feels better so now I can actually ride. The weather has started to be nice, finally. Now I can't ride cause Mr. Moto won't STOP.

Any other advise would be most appreciated!

Thanks!

Also sorry guys, I am new to this forum. Don't know how things work.

Take the bike to a brake specialist or motorcycle dealer. It is your brakes you are talking about here not how to adjust the mirrors.

Right, K1W1 !!

As a follow up, I did watch a vid on how to bleed the rear brakes. So I got some Motul 600, and went at it.

I was surprised cause there was NO pressure at all. But I got the drain tube and reservoir, found the right size wrench, pumped and opened it up, POOF some actually came through! So I just kept at it. All kinds of air bubbles and darker looking fluid. At one point, it was all orange and frothy. Finally after tons of pumping, and a half bottle of fluid, it came through nice and clear and no bubbles. Now I have nice firm pressure and awesome brakes again. It has been 3 days now and they are holding fine. I am prepared to do it again if needed.

Thanks to K1W1
