Just changed my rear brake pads on my 94 honda magna. They are drum brakes and I re-installed all compononets correctly and testing the stopping ability while the bike was still on the lift-worked fine- but once I took it off the lift and rode it around the rears dont work at all. Its almost as if they arent there. I thought maybe a spring popped off or something came loose so back up on the lift it went. Tried spinning tire while on lift and it stopped just fine. Took the wheel off and inspected everything and it was fine. Tested stoppage one more time on lift-fine. Took it off lift and rode around and same problem again. No stopping at all. I messed with some of the tension adjustments on the brake rod (or whatever you call the things that connects to the hub on the wheel) and no change. Do I need a new drum or is something else going on?
