stock pads

Porterfield makes their pads in batches. And considering that the run rate 
on our application is pretty low (relatively speaking) they probably make 
smallish batches. I once received a set of pads that they'd made a mistake 
on...wrong backing they would not fit at all. My subsequent 
conversation w/ them revealed my limited insight into their production. So, 
some variability between batches could be expected although I would contend 
that quality control should be stepped up.

The whole "beveled" pad shape that you see makes no sense to me. I trust 
that you measurements are correct. But there is absolutely no reason why the 
center of the pad should be thicker than the edges. I've see a little 
bevelling at the very edges of pads before....but to have the thickness of a 
pad vary ALL the way from edge to center seems like it would have to be a 

I should mention that Porterfield did "make things right" after their error 
w/ backing plates.
