HELP ON BRAKES R 2012 RT Camera Head SPONGY brake SUCKING SOUNDS

OK< I read all the posts, Have a spongy front lever for the 2012 ABS system , decide to bleed rear.
so did it normal, Nothing comes out of the rear, Pump, close, pump, close, etc.

So I put a clear hose over the bleeder valve loosened it, pumped sucked, closed, pumped sucked close, some fluid came out and lotssa bubbles, than no fluid (from the bleeder holes, I think)......I should be getting fluid, nothing coming out...BOY was my wife laughing at me while she pumped...NOT FUNNY SAYS I..Ha says she..

ARRGH What is going on no fluid means no brakes in the rear, I have not taken it out on the road yet, but the light was NOT ON BEFORE.

suggestions please. HEY Maybe I have to use the rear brake peddle??? instead of the front lever

I will assume that is a joke.

"Standard method" will work fine but it is nice to also get any bubbles out of the ABS block also with a GS911.

For rear I:

Pulled caliper and blocked caliper pistons back/in.

Cleaned out resevoir to just a couple drops left.
Fill with new DOT4 and keep mostly full as it goes down
Press down peddle open bleeder, close bleeder
Repeat until clean fluid comes out.
Then I did GS911 procedure but could have done that in middle of sequence.

I had just changed a leaking master cylinder so I got out some bubbles.

Speed bleeders are nice for old guy like me, makes it much easier.

Did same for front.

Check to see if the brake line is not twisted under the rear fluid reservoir.
I don't know if it's different on the 2012 but on my 07 the reservoir tends to turn a little in the holding clamp when you tighten the cover.
I you don't pay attention to it, eventually, the brake line becomes twisted to the point where the fluid cannot go through anymore.
DAMHIK

FIXED the problem, For some reason, LINKED NOT

OK well the front brake system and the rear are separate, I was pumping the front brake lever and trying to bleed the rear (super dumb)

I found the reservoir under the seat..Problem solved

Than it was easy to do the front, all is good now, thanks
