Got a 00 fzs600,all good but upon viewing,rear brake was stiff from sitti up,it hadnt much bite in it and to get some pressure we pumpd the pedal. BUT TODAY on my careful journey to the garage,i was braking with rear and gearing down..approx 20mph,slowin,then out goes the rear,it fishtaild a few feet before i held on in panick and down she went,any advice or reason? It was very unexpected,i dont understand,perfect rear tyre
