The car is running with EBC 4x4 pads at the moment, and they have been fantastic on genuine LR discs. It's more than likely that the discs are so worn that they have caused the uneven wear to the pads, which is to both sides as is the wear to the discs. I'll check the play in the sliders when I get them apart next week and see if there is a problem with the movement. If they're all nice and tight I'll blame it on the excesive wear and just do the straight change. And yes, I'll stick to genuine LR discs, but will continue with the EBC pads as they are ab fab. Try them and you won't go back, honestly, they stop you on a penny.
