undo the pad pins and then undo the brake caliper it has 2 13mm headed hex bolts then put a flat bladed scewdriver between the old pads and twist it to force the caliper pistons back in then fit the new pads and the pad pinds and refit it to the fork then pump the brake lever until you have a good brake,im pretty sure the front pad pins are just two stainless stell spring clips that are shoved through the caliper and thay just need pulling out ,the pads are fa 115's well on the 50cc it is the 100 may be different but i dont think it is.
