This little saga continues, I decided to put this here rather than start a new thread.
I've done the front so far, with new Pagid discs and yellow stuff pads. It looks like the discs were EBC and the pads were Ferodo, not sure which type.
Unfortunately whoever fitted the previous discs cross threaded the bottom bolts on both the front calipers. I haven't checked the rears yet but hoping these aren't the same. I'm going to get a tap and new bolts and attempt to fix the caliper (my tap and die set doesn't have a tap big enough) but if this doesn't work, would I be better off tapping a bigger thread and getting bigger bolts or would a helicoil be ok? I've not used helicoils before, so I'm not sure if they are strong enough for this application.
