Its not a difficult job but allow plenty of time so you don't rush & forget to tighten something vital. Make sure you have got everything to hand before you start-ie brake cleaner (Halfords etc), new seal kits-experience suggests go for Yamaha seals as they are guaranteed to fit. Scrupulous cleanliness is the order of the day-plenty of clean rag, paper to mop up any brake fluid. Also you need some copper grease to apply thinly to brake pad BACK PLATES and pad holding pins. Only dismantle one caliper at a time and make sure you replace pistons in their original bores.Also clean out grooves that hold seals with a soft tool to get rid of any small particlesof corrosion/dirt/etc so new seals fit properly. lubricate pistons with brake fluid when fitting and apply small amount of RED RUBBER BRAKE GREASE to exposed ends of pistons. Use the new crush washers supplied with your new line kit-throw the old ones away-theyre not reuseable. When bleeding system wrap towelling around master cylinder to protect paintwork/tank etc-brak fluid I very corrosive. Use fresh DOT 4 fluid . Haynes manual explains it all.
