I have just notice it recently and the adjustment dial is @ 5 right now. Sometimes they are ok and sometimes they feels tight when I break. I have just a little over 15,000 mi on my 03. My break fluid is fine. Is it time for them to be chg. I haven't anything to them since I had the bike. Meaning that when time I squeeze them they brake instantly instead of a little play before max. pressure kicks in. What is the problem?
