I've been noticing the free-play in my front brake lever keeps increasing. Seems like I have 3/4 free play and only the last 1/4 where the brake actually starts to grab. I checked the pads, they're almost dragging on both sides and the adj screw on the lever is almost all the way out. So Hmm, I thought. Maybe they need bled. Half a can of DOT 4 later, still no improvement. I notice that there isn't really any sponginess to them; just on the first 3/4 of the piston stroke a little bubble of fluid actually shoots up out of the hole in the bottom of the reservoir. I may have had the lever too tight, dropped the bike and forced the lever in and blown up something in the master cylinder. Anybody else experience this?
