No they don't. It pressurizes the container and pushes fluid through the hose to the master cylinder.

Before I bought a motive I had a selection of brake caps with air fittings on that were hooked to a regulator at low preasure

they work like a bug sprayer, the bottom of the air pump is in the fluid, every time you pump, it puts air into the fluid. You can pump them up a couple of days ahead of time and let them sit until the bubbles separate out, but I dont have time to wait. I wound up using a paint pot, it puts air pressure on top and forces the fluid out the tube. @mrblaine understands that and I dont mind poking the bear.

Crap, I'm wrong!
Not "crap" because I'm wrong (I'm wrong all of the time, just ask my wife)
Not "crap" because you're right.
"Crap" because it is aerating, to some extent at least, the fluid.



Nope.
Air "in" is from the plunger/cap assembly. You can see the flapper on the underside, if you look. Fluid "out" is the tube in the brake fluid.

Didn't Blaine say all these suck, @astjp2 do you have any luck with these?

Edit: I'd reference Blaine by his username but it's like poking a sleeping bear with a stick
Generally, anything that works for you is good and anything that doesn't is bad. What works for me is a good manual bleed. I fix a lot of gadget bled systems with a manual bleed. It is also rare that I work on a brake system that doesn't have air in it.

What are you trying to say? Maybe we need to get @Chris to intrepret?

I always use one of those vacuum brake bleeder systems. Bought one 10 or so years ago and it's always worked like a charm.

Admittedly though, I've never tried speed bleeders. Are they all they're cracked up to be?
