I have the version that hooks to a tire for the air feed source. Minus the air hose adapter being really cheap and plastic, the system works great. After the 3rd or 4th use, the plastic connector started sticking/leaking air. I plan to buy a nice metal fitting or canibalize a bicycle pump, since those seem to have nice Schradeur valve adapters. It makes flushing the brake system insanely easy and only takes a few minutes from start to finish. In the time it takes to gravity bleed one caliper, you will have all 4 corners done and cleanup started.

Anyone ever use these type of bleeder-bottles w/ built-in check-valves?


Seems like a better solution than using those speed-bleeder-screws. (I’ve used those screws/valves in the ‘90s, but I never liked the idea of using a more complex bleeder valve/screw with added tiny internal parts… I always preferred solid oem bleed screws/valves).


But, that hand-pump seems like an even better idea! (no need to jump in&out of the cabin to pump brakes all the time)
Never seen that method before, but I think I will try it next time!

Do you have a link for this?

Do these work by pressurizing the master cylinder brake fluid container and letting the old fluid out at the brake bleeder?

Yep. These force clean brake fluid into the master cylinder by pressurizing that bottle. Appears to work off a tire and not a compressor so it's about 35psi. Open each bleed valve and the pressurized fluid should flow more quickly than gravity will push it.

The other options are the devices that suck it out at each brake cylinder and the bog slow gravity method (which I gave up on after a few cc's in an hour).

$75 - $100 (like this or the YS4000B vacuum pump) is a lot of money for a device you're only going to use once every five (5) years but "group" use could make this reasonable.

I'm going to check the Harbor Freight (AKA One Time Use) bleeders next time I'm over there. $20 every 5 years seems reasonable.
