Also I find that topic a bit confusing because the topic starter has a quote that he's referencing in his topic that says.....
"The mechanical difference boils down to the updated caliper being much larger to hold a larger pad....The early style pad (in the 13WE caliper) will be less than 5” (4-11/16” or 199.5 mm) in width; the (pads in the) later update (13WL caliper) is more than 5” (5-5/16” or 231 mm). Both of the calipers have the same dimensions on the mounting bosses......The update (to 13WL calipers) will replace the (13WE) calipers with a larger set that will provide additional swept area and fluid capacity for heavy-duty use.

The math in that quote is not accurate ..."(4-11/16” or 199.5 mm)" and "(5-5/16” or 231 mm)".... 4-11/16' = 119.0625 or 119mm not 199.5mm and 5-5/16'= 134.9375 or 135mm not 231mm.
The only thing I can think of is his math is referencing the width of the caliper in mm for a 4-11/16" and 5-5/16" pad and not the pad itself.
