So I am getting my Akebono's powder coated tomorrow and I need to strip down everything including the pistons. I see you need compressed air to push it out. But I don't have that currently to my use. Is there anyway around it than using compressed air?

 

Why not just bring to a local shop and borrow a few sprays of their compressed air?

A grease gun is pretty common but messy. A GOOD bike pump can do it but the best way, is while the caliper is still connected to the stock lines. Just pump the brake pedal and boom. Just be careful, once its loose, it tends to come out like a rocket..

 

I get off @ 6:30, majority of auto shops are closed by then. And my appointment is @ 7 in the morning that's why I needed a different way. Oh well I'll just tell them I could not get it off.

 

I highly doubt there is any bike pump in the world that can produce enough CFM to push the pistons out. Also it will be tedious to pump the brake pedal and push all 12 pistons out equally because if any one of them get popped out prematurely, you will lose all pressure.
