I know there are several brake piston spreader options, but here's what I came up with.
First, I ordered one of these--yes, I know, its a Corvette site, so don't flame me. ;D

It does a great job on 2 pistons, but we all know that pushing one pair back sometimes causes the other pair to push out.
So I modified it into a 4-piston design.
I bought an 1/8" x 1 1/4" piece of strap iron, cut pieces 2" long, and welded them to the sides.
I welded on the inside so the outside that pushes the piston is smooth.
Sandblasting and paint makes it look pretty good.
To use, slide it into the caliper, and gently turn the handle until pistons are set back far enough to get replacement pads installed.
