Maxima Rear Brake Caliper Problem

["Brian Berryhill" <brianberryhill@usa.net>]

This isn't directly autox related, but I thought some of you might could
help.

My sister wanted to autox her 1990 Maxima, but I told her I needed to change
the rear brake pads first since they're so worn down.

Problem is, I have no idea how the piston goes back into the caliper.
There's no retraction screw, and a C-clamp doesn't work.

Is it possible that the piston twists in?  I know how my car's rear calipers
retract, but not Maximas.

Thanks for any help,
Brian
