When I first got my YZ the brakes performed amazingly. I could do stoppies with little to no effort, and the lever feel was tight. Now, for some reason, My brakes have lost their umph and while they still stop me, the original strength isn't there anymore. I thought my pads were glazed or had maybe gotten some oil on them so I swapped my pads for a new set EBC sintered pads, and bled my brakes. The feel is still the same, squishy with no firm grab. I am going to take off my rotor and have it media blasted, but what else can I look at as a cause for a loss on brake power?
