I got trapped with dead pads one weekend and _had_ to change the rears without 
the special tool.
 
I made one from the bar that clamps a television aerial onto a mast.  These 
things are fitted with wing nuts - I took a rod out of a clamp, dropped one 
wing nut into the channel on the bar, and wound the other one on the other 
end.  This fitted nicely into the caliper to exert pressure on the piston while 
I turned it with a pair of thin-jawed water pump pliers.
