Sorted it! I had already lubed the pad sliders (not sure that's the
correct term but the bits of the backing plate that stick up) and
backs with copper grease when I replaced the discs, but after
searching about on the net I found a few other makes (mostly MGB's and
people who have fitted EBC performance brake pad/disc combos to
Imprezas and Skylines) suffer from the same problem and the solution
is to file off the leading edge of the brake pad so it doesn't grab
the disc. So I rounded the leading edges off all the pads and cleaned
and re-lubed the pad sliders with copper grease and hey presto 99.5%
reduction in squealing. Not bad for half an hours work - and to think
I've been living with it for the past four years!
