I picked up a Harbor Freight brand vacuum bleeder. How well do these things work?
Not as good as the good old pressure cap, but not bad.
Mighty-Vac, well like the name implies it sucks. No actually it's OK, I use it for bleeding brakes.
My prefered method is to:
1. Suck the old fluid out of the reservoir
2. Refill with new fluid (your choice if flavor)
3. Go in the recommended bleeding order per manafacurer, or by rule of thumb, furthest first
4. Attach overflow bottle to speed bleeder and loosen bleeder just enough to break seal
5. Have buddy pump brakes till clean fluid comes out
6. Go all the way around twice, and on the second time around pump till the fluid is really clean and there are no bubbles.
7. Optional: grab another beer and figure out what else you want to mess with on the car
+1 ... I've used both and the pressure cap can't be beat!Quote:

I'm sold on speedbleeders. Not all vehicles can use a pressure cap (cough, Windstar, cough).
I used mine last night after putting in a new clutch slave cylinder... quick and easy.
Those things can be a PITA to use. I prefer speed bleeders.
I've used one for years. I had a Fiat that took forever to do it the old fashioned way. The speed bleeders would'nt work and the tank was old and brittle, so a pressure cap was out of the question. The vacuum method was very easy and thorough. Start on the furthest from the master cylinder: right rear corner, then left rear then right front, then left front.
