The left brake on my FA50 lately hasn't always been operating the kickstarter properly. Its supposed to make the kickstarter stiff but once in a while it will just stay loose unablr to be kicked over. Would the rear brake pads maybe have anything to do with it? I have no idea how that lever works so I hope that isn't a dumb question about the pads. If I loosen the tension on the brake cable, it usually will operate correctly then. But the brakes then are not sensitive enough.
