Removing seized Kelsey Hayes pistons

Removing seized Kelsey Hayes pistons

Air psi had ZERO effect at approx 140. TONS more psi AND effect with a grease gun lol, not sure if its safer or not but mission accomplished.
Mike, when I went to post info in "how to", I posted it to "steering/suspension/brakes" no idea how it got here, but like you said info is out that's the main thing.

Another advantage is its a bit safer using the grease gun and hydraulic pressure instead of compressed air.

I saw your "how to" thread and ok'd it. I see this is in Brakes now. :BangHead::BangHead: At least your information is out there. I forgot about the grease gin approach to force pistons out. I have never rebuilt calipers but These KH's are hard to come by. Getting the rust pits out of the housings would be the hardest. I imagine the rebuilders machine to a larger bore and use a different piston.
