Seriously though, I hate those self-bleeder bottles. The magnets are garbage (particularly when they sit lower than the metal housing and you have to grind the damn thing flush to get a proper grip), and you better hope the hose doesn't pop-off lest it sprays fluid everywhere. Especially on your pads or shoes which you've then contaminated. Plus then you have the concern of still having bubbles escaping through the threads, as Dave pointed out. Which then leads to air going back into the system. Also, those check valves are great when you're working with clean fluid. Not so when you have dirt in the system that clogs them up.
Bleeder kits are cheap. If you build one yourself, it's less than $30. And with the exception of keeping them segregated for DOT3 vs. DOT4 use, it's a tool you can use over and over again on multiple cars. For club events, or other cars you own when you fabricate some additional adaptors.
Yeah, you don't over-pump the reservoir. About 13 PSI will do you just fine, and gives you like 20 or so seconds of fluid flow. Then you can witness the purging of bubbles and bad fluid first hand. Then you just go back and re-pressurize the bottle as needed. Doing this there is no risk of damaging the internal pistons on the M/C. The best part is a little trick for the reservoir adaptor. If you build your own, make sure you put a fitting onto the end of it that goes down into the reservoir. Then cut & deburr the end to match exactly with the MAX fluid level line inside. Once your work is done, lower your pressure tank BELOW the M/C, and then crack it open. What it'll do is siphon out the excess fluid and leave the perfect level behind.
Is there some "wasted" fluid? Yep. But there also are no funnels & tiny collection bottles involved. So you avoid spilling the fluid onto the floor, and especially all over the frame to destroy the epoxy. The price of an extra bottle or two of brake fluid to avoid that kind of damage is money well spent IMO.
The problem with that though is that the calipers are far dirtier than anything else in terms of grime & rust.
