the brakes are fantastic on these bikes so something sounds amiss,if the fluid hasnt been changed for a while then do it anyway,its a 20 min job to change it all and bleed it all up,it could be that you have a sticking piston or air in the system etc if there not great and possible the rubber hose is past its best ,iv just rebuilt the back one on mine and much improved with new piston seals,pads,new hose etc but my fronts are great still,bleeding brakes is simple all you need is some new fluid and a jar(jam jar etc)and small piece of hose clear if possible,the worst bit is if the bleed nipples are rusted shut !
