Kelsey hayes brake calipers?
I have wondered if a left (or right) could be drilled tapped etc to have a bleeder on both sides. I guess you would have to machine for the hose as well.
Not worth the effort, labor time, for machining to do anything like that, as long as calipers are still available to be found and purchased.
They are getting pretty hard to find these days, but with some searching they can be found, in rebuildable condition, or already rebuilt.
If by chance, you're looking for calipers, look in the for sale section of this forum.
I can set you up, with a rebuilt pair of them, or just a left single.
Well, i no longer have a pair of calipers that i can sell.
They SOLD this afternoon.
