My front brakes on my 2003 fzs600 are sticking, it's only done 8,000 miles from new. I've just wound pistons back in.re fitted. And there still binding .is it worth talking the caliper off, pulling pistons out, lightly cleaning and re fitting, WITHOUT, buying a new seal kit, which are quite expensive for both sides, if buying genuine. I've heard using 1500 grit sandpaper on pistons, and leaving old brake & dust seals in. Then just refit nice clean pistons. Any thoughts , anyone ?????
