Mark read the bit about "it may be more a design issue", peculiar to the evo brakes.
I wouldn't work on a evo, just not my thing although I admire the technology greatly, they look a pain in the arse to work on compared with a cossie, and only ever done some basic jobs on some evo's, of which the earlier ones are much more to my liking.
I wouldn't use "taxi" pads anyway.
