Yeah reman calipers almost always ship with air in them, the boxes sit on shelves for months and that fluid settles out. Tbh the bench bleed is non negotiable for me now, takes like 10 minutes with a hose looped back into the reservoir. Did a set on my buddy's truck last summer and one of them was dry as a bone out of the box, no way that would have bled out right on the truck. Phoenix heat just makes it worse too, fluid gets thin and that air loves to hide in the lines.

A buddy of mine has a similar story with a cheap coffee grinder he got at a garage sale for like eight bucks. He's gone through three fancy burr grinders that cost over a hundred each, all of them dying within a couple years, and that little garage sale one just keeps grinding away. The thing is, those old simple machines had maybe one moving part and no circuit board to fry. My friend says the fancy ones all have some sensor or chip that fails, and when it goes, the whole unit is trash. Meanwhile the cheap one just has a motor and a switch, so there's almost nothing that can break. I keep telling him to hold onto it forever because they don't make stuff like that anymore.
