Shed time today. Top end on 165 done, greased front brake pins, linkage, shock n swingarm. Went to grease rear brake pins n nuthin at the pedal! Havnt ridden the bike for 3-4 months. I've tried bleeding it normally n reverse but won't build pressure! Banjos look ok n hose too. I'm assuming the seal inside the master cylinder has crapped out? Sound feasible? Havnt had much to do with brakes how do I check?
