bleeding brakes

Wasn't implying that pulling air in past the cylinder seals was a good thing, just not sure that it's bad beyond now having more air to get out of the system..

Ya know when I used to drive up into Mom and Dad's house I did NOT come driving in through the back woods, which is what you are arguing here. If pulling air in "is not good," then it "must be bad" Air is either good or bad, in this case bad. So don't get this twisted around in some sort of alternative logic.

I don't use pressure bleeders and won't allow their use on my own stuff, even when available. The reason is simple and has little to do with pressure bleeding itself. It has to do with the brake fluid in the unit. How long has it been out of the bottle absorbing atmospheric moisture? I'm not going to guess or take a chance. I want the fluid going in to have the highest boiling point possible, and that isn't going to happen with fluid coming out of a pressure bleeder.

There is NO reason to assume that just because you are pressure bleeding a system you are using contaminated fluid. Bleeding by pumping the pedal IS pressure bleeding. What, you have a 55 gallon pressure bleeder? I sure as hell don't. Mine holds about a quart of fluid


This is quickly getting to be the silliest argument I've seen lately. I have a suggestion. Go ahead. Get out the vacuum pump. Pull a Great Big vacuum on YOUR system if that's what makes you happy. Hell I've got at least two pumps sitting here from my HVAC /R days. I sure as hell don't use 'em on brake systems.
