'07 CBR 600RR.
Bled my brakes in anticipation of the track day on the 18th. Everything felt good, went for a ride. When I returned, I found some fluid seeping from the right side caliper bleed screw, coming straight from the threads. Not gushing or anything, but a very small gradual seep. See pic below.
I went to the dealer and bought a new bleed screw, thinking it might be defective. There is no o-ring or seal of any kind in this caliper. It is screw and caliper. That's it. So it's one or the other.
I pulled the old screw out (without draining fluid) put the new one in and re-flushed the brakes because now I introduced air into the system.
Rode around, brakes felt fine, but when I got home I found a tiny bit of fluid again, just enough to cover a small spot on a towel. See pic below.
So it's not the screw.
How do I proceed? Before you ask, out of warranty.
I think I'm going to drain the fluid tonight, and clean the caliper threads with a q-tip.
