You need a hex (allen) key or socket - I forget what size but it's
weird, like 11 mm or something.  I think I ground a 12 mm one down a bit
once... tihgten, I think, clockwise on both sides, while applying some
force to the piston (with a c-clamp or something like that)

Rear calipers.  The screwing is required to undo the accumulated "self
adjusting" they do to keep the hand brake wokring.
