I recently lubed my splines,and while installing everything I forgot to put that center spacer back in the hub and tightend it all down.I herd a pop inside like a deep metal thing,and the tire wouldnt rotate.Low and behold theres a metal spacer over there on the tool box and realized what I done,took it all apart and put it back together,everything seems fine.I adjusted the brake and went for a ride.During the ride I noticed that my back break wasnt catching until pushed way down(had to use my heel to push it far enough to get breaking force) but it worked fine..The extra travel needed to activate the brake seems to be inside the drum,I was planning to take off the lever at the drum and preload it a tooth or two and adjust until a very slight drag.What you think? P.S about how long will the rear brake last.
