Yep, I can vouch for that. I had brakes after using just the pressure bleeder, but a mushy pedal. And that's on *both* of my Supers which suffered MC failures at the same time, so I just ran thru this on both cars.

Yeah, slight drag. I could spin the wheel easily by hand, but I didn't have them so that they roll freely for more than a turn. I have in the past roasted the brake fluid by leaving them too tight.

Yep, same clicks back off per star...give or take a click.

| mines a snap-on....it has quick a quick disconnect that'll puke a little when it goes on or off and the cap that screws onto the master is a joke so if it doesnt seal right you have a flood...but what do you want from a $200 garden sprayer... |

The motive cost me $50 about 3 years ago. Guess I got a good price!

| Read my instructions early on in this thread. I recommended to adjust the shoes tight against the drum and to not put fluid into the container to avoid spills all over your paint and an unnecessary clean up. |

74 Thing, not sure if you're addressing me, but I got the Motive bleeder on and off w/out spilling any on my paint.

I’d like to make this modification to my power bleeder, but I’m having trouble finding this swivel fitting.
What are the size specs and where can get one?

That looks like a 3/8” Hydraulic fitting or possible a gas fitting . Might have something like that in the propane barbecue section of local hardware store. |

I found this to be the easiest/cheapest 1 man bleeding system they have. These sell on Amazon for around $7-9, it's just an inline one way ball check valve. You put a small 6" piece of clear tubing on one end, and a longer piece on the other side farthest from the bleeder. Get an old 2 liter plastic bottle, place the longer end in there. The short end of course connects to the brake bleeder making sure you have the correct direction of flow. Crack the bleeder, and start pumping. That's it!!.
The ball valve will only allow the fluid to flow one direction, it allows you to pump all the air out, and never let any air back-flow into the system. I have been using this method for over 20yrs, never has failed me

Interesting idea.
I assume you flush the check valve with water after your job is finished.

I blow it out w high pressure air from both sides. i've used the same ones on so many vehicles over the last 15 years, no way could I ever count. But I do know that, this is the most fail proof one man bleed job you will ever come across. you can even use it to gravity bleed the system solo. Hook it up, and let science do it's thing. The only worry with this system, is forgetting to stop and fill the reservoir. But even then, I have done it many times, and fill it up, then go back to pumping pedal until all the air is gone. |
