[s-cars] Motive Power Bleeders...?

Purple people eaters from the vanguard of space made Mike Sylvester say:

I thought about these two items and did this...

1. After use, clean with denatured alcohol as described in the instructions, but before you do that...
2. Just pressure push the remaining fluid out into your original container. Contaminated is relative here and cycling fluid through a clean bleeder shouldn't contaminate it.

To make this easy just use a male air chuck fitting which snaps on to the bleeder's line. If you make a male to male one of these you can also use it to push filtered shop air back through to dry it after cleaning.

The biggest reason to put fluid in the bottle is so that you don't run out of fluid in the reservoir. Don't know about you but when I do this, I move at least 1/2 liter through to the right rear before it clears. There's no way 1/2 liter of fluid is in the reservoir, so you'll have to release pressure, fill, and re-apply pressure kind of defeating the purpose. And *that* more than anything else will introduce dirt into the reservoir.

But if you want to go that route, no need to buy the pressure pump, just get the right fitting for the car (I think it's the 1100) and connect to your shop air supply.
