Hi, I have been attempting to replace the front dics/pads on my Ypsilon (2011 model). It appears the brake caliper is held in place by a carrier which needs to be removed in order to lift out/replace the discs. Looks like it is held by 2 x bolts but the heads look strange. Does anyone recognize this and can you advise me what tool I need to remove these bolts please and where I might acquire the tool? Any help gratefully received - Steve
