Ok not sure what happened here and am stuck. Was bleeding the brakes per the service manual. Had the vacuum on the bleeder and was slowly pumping the rear brake and getting old discolored fluid out. Got about one res of fluid out and kept it full the whole time, but all of a sudden it stopped sucking fluid and the pedal doesn't push any fluid out.

Can't seem to get the cylinder primed I guess is the best way to put it.

Any help to get the fluid flowing again would be appreciated.

Thanks!

Get another helping hand. Fill res and then pump break pedal and hold down. Now have the helping hand open bleeder. Keep pedal down till they tell you bleeder is closed. Pump pedal hold down and them open bleeder. Hold pedal down till they tell you bleeder is closed. Do this over and over till you get a solid stream out of bleeder screw

Im not sure what going on with your brake system, here's what I've done: Replace your stock bleed screws with SpeedBleeders- my Vision took the SB8125's & I'm guessing the Cross bike's are the same. Ditch the Mity-Vac and simply open the speedbleeder and pump the lever/pedal while topping up the reservoir. It makes it so easy you'll be changing your fluid before it's called for on the maintenance schedule. I have these in all my vehicles. I also highly recommend Motul 5.1 full synthetic fluid-I've been using it for years and it's top shelf stuff & fully compatible with DOT 3 & 4 fluid.

Thanks for the replys. Here's the one issue that is stumping me. The pedal isn't pumping fluid all of a sudden. Like I had said it was going perfect then with one pump I lost prime for lack of a better word.

I did see a tip on another site I will try later when I have time. That was to put some thread tape on the bleeder threads to help them seal while the bleeder is cracked open so the threads don't leak.

Ok I am a total and complete idiot of the highest degree! Clear head today so I can think.

I put my vacuum on the bleeder nipple and pull a steady vacuum. Take off the banjo bolt. Yep got suction. Put back together. Pull another vacuum open bleeder. No suction. Go to master cylinder and pull banjo bolt. Yep I have suction and now completely empty lines.

Ok now what??? Well I decide to empty the brake reservoir. What the heck? I pull out the rubber top seal that had gotten pulled down and blocked the flow of fluid thru the system.

My Kaw's never had that on the rear, but only on the front and in my fairly dark basement garage I didn't notice that black piece of rubber.

Take the rubber out and fill it and reprime the system and guess what. I have brakes. LOL everyone laugh at me cuz I am.

At least I know I have a total and complete flush job now! Sometimes I can be such a Dolt!

One last thing of note now after test ride. Since I got air in the system I had to hit the rear brakes hard to get the air out of the ABS unit. Then come back and bleed just a couple pumps of the brakes and now they are back to 100 percent.

The fronts were simple since I didn't let air into the system. One complaint though. The rear and right front calipers both take an 8mm wrench and will suck air past the bleeder threads. The front left takes a 10mm wrench and doesn't suck air around the threads.

Hope this helps someone else down the road.

mity vac no pumping

when i recently did my dual disc on 2013 hammer i just kept suction on + master full, closed bleeder only to dump fluid in mity vac collector. strapped brake lever overnight with master just covered by a clean rag, rock hard brakes from fully empty setup. speed bleeders sound good for sure
