Hi all, didn't find anything on this subject so I have to ask. When I press my front brake lever in to stop the bike, it "kinda" sticks a little and when I give extra pressure, the lever "unsticks" and pulls back further than I want and the front brakes goes on harder than I intend. I then have to let up and "speed-press" on the lever to get the bike to stop at the rate I want. This is new to me, so I was curious - Is this a WD-40 fix or fluid change? Or????
