I remove the wire clip, then use large channel lock pliers between  
the back of the cylinder and the tab on the inboard pad.  That  
retracts the piston all the way into the caliper.  I then pull out  
the inboard pad, pull the back edge of the rotor out, and slide the  
whole thing forward and out off the hub.  It's a little close  
clearance, but never impossible.

I had to bevel the pads I got from Porterfield quite a bit with a  
file to get them to fit.  A lot of pads come that way, yes.

Tip: to remove the ridge of rust, use a carbide scraper.  Peter  
Schulz tipped me to this, and it cuts through the stuff like butter.
