I'm trying to convert my drums to discs, so I bought a pair of second hand
discs that I needed to recondition. while changing out the discs and pads
and brakes hoses, the caliper pistons got so close together that I can't get
the pads around the discs. what's the correct way to retract the pistons.
thanks

I usually lever the pistons back into the cylinders with a big screwdriver
or tyre lever.
But I do it with the OLD pads in place, rather than the new ones.

There is a proper tool you can buy, but a flat lever is usually OK. If you
have fluid in the system, open the bleed screw to make it easier to push
them back.

Not very successful as there is insufficient leverage with the tool = as
mentioned a big screwdriver or tyre lever with the pads in.

The screwdriver / pry bar trick is ok, but the best way is with a
large enough c-clamp, or "channel lock" (expandable plier), and, with
the one pad on the piston, squeeze it back in slowly. Don't forget to
open the master cylinder cover. (I prefer to open the cover over the
bleeder screw, as sometimes you may get air in the line that way.)
