I have got a 2012 STX 2wd that has done 26000k. It has an issue that the right hand inside brake pad wears out in 7000k(yes it has used 4 sets of pads). Have taken this up with our local dealer in NZ and we keep getting blamed. The ute is used for a rural mail delivery does 300k per day. I have replaced the nissan pads with aftermarket ceramic 4x4 pads and still the same happens. I think that the pistons are not releasing properly but Nissan non comittal. Anyone else have any ideas.
