Vision spongy rear brake pedal
After a period of storage it’s common for the Vision’s rear brake to collect air and become spongy. The air is easily bled out from the front right caliper as seen in the video.

Note: I never suck tubing…I use a syringe or turkey baster. I then open any bleeder with the tubing attached. I then pull the handle/pedal and strap it in the “open” position. This allows gravity to do the work rather than pumping and possibly introducing air into the system. I continue to maintain a visual on the reservoir and keep it topped off with DOT fluid until the bleeder valve has clear fluid coming out. I also use speedbleeders-a one way valve but that’s my preference.

I used the speed bleeders all around about 2 years ago. Next spring will do again but most likely with a mighty vac. Its suggested to use a vac because of the ABS components. Also when pumping up the rear pedal you really need to do it slow. Any fast mashing of the peg will just put air bubbles in the fluid regardless of anything.

My 08 VV is pre ABS so that is a factor in my method

Storing the bike upright will avoid the spongy pedal after storage. It has everything to do with storing on the side stand.

The 2016 I recently bought sat for a while and has less than 3K miles on it. I’ve bleed the brakes from the front and back calipers with a vacuum bleeder and I still have spongy brakes. I take it from the manual the next logical step is a new master cylinder. Is this common with a Vision that’s sat for long periods of time? Also what size speed bleeder does the Vision take? It’s not listed in the manual.

Got tired of bleeding mine every spring. There was an issue with the crimp on the rear brake line that somehow let air in to the system after sitting for a period of time. I replaced the entire rear brake line and haven’t had an issue since.

Ok. Now it’s my turn. With the added difficulty of being in Spain.
My 2010 Victory Vision Tour with 99.000kms has a spongy rear brake pedal. After reading several posts and learning about this well known problem, I took my bike to the Indian official garage in Madrid. Unfortunatley there aren’t many Victories around in Spain.
They bleeded the breaks, but it showed no improvement. When I press the break, it only shows effect at the very bottom as if it had no power steering, but if I press it again it breaks as it should.
The garage asked the Polaris headquarters in Spain and they gave them new bleeding procedure instructions (including leaving the bike several hours). They just did it, but unformtunatly with no improvement.
I’m running out of ideas…

Update on my previous post:
I’ve just seen a video in Youtube showing the valve pointing to the rear of the bike. The one in the middle.

I just sent it to my garage and they told me that they tried to bleed it always from the upper valve, not the other one. They will try it now, and I will post the result.
Thanks in advance.
