The EXC 450 I just picked up doesn't have any brakes. I argue that bikes like this do not necessarily NEED brakes, but alas, I have been outvoted and need to fix them. The bike has sat unused for 2 years. They worked when it was parked.:huh I am going to try to bleed them now that I have the DOT 5.1 fluid. (Glad in my older age I have learned to read instructions... ie, manuals) Is this a common issue? Anything I should be on the lookout for or should do?
