MityVac MV6830 Brake Bleeder

I bought a handheld MityVac years ago, and suffered the issues aforementioned. It's messy, sloppy, tedious, and of all the included adapters, none fit well. Even with the aquarium tubing it was a pain.

When @Igofar convinced me to buy the $15 Motion Pro tool, and the rubber children's aspirator, I knew I had been shown the easier way. Properly bleeding the brakes with his help was easier, cleaner and quicker.

Whatever works for you works I guess, but I'm always about learning an easier and better way to work on my ST. Larry is right, when it comes to these bikes, far more often than he is wrong.

(Not that I actually know when he has been wrong, but I'm sure he has been. Just because.)

Which $15 Motion Pro tool and 'children's aspirator'? Pictures and/or links?
 
I purchased the hand pump MV8000 model but don't use it. About the only thing I've used from it are some of the hoses and connectors. I'm another one that uses the Motion Pro Hydraulic Bleeder (08-0143) and children's aspirator (bought off Amazon) per @Igofar. Another example where KISS methods work best :thumb:.
 
Years ago I restored my first Guzzi and replaced all the brake hoses with new SS braided lines. My neighbor and I (he had built several and raced them as an amateur) tried to bleed the brakes but the pedal and brake lever remained spongy after several attempts. He finally pulled out his Mitey Vac, and that did the job for us. I bought one and it served me well for years, but the o-ring on the jar died as did the internal seals (this took over 20 years) and it no longer pulled a vacuum. The parent company changed the design and discontinued the repair kits. I choked on the new price. Since then, I've used my Robinair vacuum pump with an old 2 1/2 gallon metal gas can as a reservoir to bleed brakes and change oil. This is admittedly overkill, but I'd bought the pump to do some veneer work, and I had it. Any good vacuum pump makes single handed bleeding easy.

Motion Pro Bleeder Tool, here at Rocky Mtn but I got mine at Amazon.

Then there's the "childrens aspirator bulb" search results at Amazon. If you buy one at a legit drug store, you could pay as much as a whopping two dollars. Think of the nasty things some of us used to use to get the snot out of kids' noses. I had 3 younger sisters, I may have used it that way... many years ago.

Really? I'd be glad to have just two of your 'methods' - that will leave you with one to spare ... ;)
Then I could see if there are any different than what I am already doing.

If you have compressed air, something like what @ST1100Y is using works well.

In the shop I use my air-powered thing, way more comfy...

attach, open the air-valve and let it rip... this thing really draws... you'll have to keep an eye on replenishing the reservoirs...

I made my own vacuum bleeder by soldering a long and short tube to a jar lid and sealed the lid to the jar. It works ok, but the trick is to put a vacuum on the bleeder and the jar, then crack it open. A little air bubbles aren't so important if you close the bleeder before the vacuum in the bottle runs out. Nice thing about the glass jar is you can see the color of the fluid when it does go into the jar.
I have purchased a pressure bleeder and will have to make a plate for the clutch and front brake master cylinder. I have used pressure bleeder for years as a mechanic and that is the best way to go for most jobs. I hated losing access to it when I retired. I had to buy my own, DANG.
 
I have a MityVac MV6830. It does what it supposed to just fine. However vacuum bleeding has all the limitations that have been already mentioned pulling in air though threads and the like.

I would get a Motive Products power bleeder instead. I use mine frequently. I had to build my own adapters from spare master cylinder resevor lids for the ST but I use their adapters on the cars with success. There is a lot to clean up in-between uses and I tend to go through a lot of fluid but it is great when working by myself.

Tony - Like this one?

 
Yes that is the one. They have them with different caps, I'd pick one to Match one of the cars so you can get some use out of it. They have the basic red label model and a black label that is up-market somehow. I don't remember the difference but mine is a black label.
