I use a Mighty Vac to flush/bleed the brake fluid on my bikes, cars, and truck...
The Mighty Vac kit came with an automatic refill bottle, I circled it in the pic below.
I don't know why, but I've never used it on my bikes....
For some reason, on the bikes I just turn the vacuum bleeder on/off to check the reservoir... maybe because I'm standing right there and not going from under the vehicle to under the hood and back...
I'll have to try it on my bikes next time.
However it works great on my cars & truck!

Put the brake fluid in the bottle then squeeze it out into the master cylinder as needed. Of course discard the fluid that is not used when you are done as it will get contaminated with moisture.

I've used them extensively on cars/trucks too and they work great.

I could do the same thing by just pouring it from the bottle into the master cylinder. I'm looking to avoid stopping/starting constantly to check the fluid level.
It looks like a cool tool! I've not seen anything like that. One of my biggest fears is getting distracted........ SQUIRREL...... while bleeding brakes/clutch and suck just one air bubble in the line and then you're screwed for and hour trying to bleed it out. Especially the front brakes where the bubble has lots of places to play hide-n-seek.

Speaking of squirrels, I was using a Mity Vac on my Audi several years ago and got distracted. After blowing all the fluid out of the master, the entire line and caliper I was bleeding, I ended up taking the car to a mechanic after bleeding for over an hour just to get half a brake pedal back.
OP: How would you attach the bottle to the master cylinder? I don't see how that would stay in place while bleeding at the caliper.
