Just finished putting in a couple new front M/C piston seals and was bleeding the brakes when I noticed brake fluid was
spraying up a bit inside the fluid reservoir. I emptied same to see a small pinhole that would squirt fluid when the lever was depressed. Pinhole is inside the circular dimple....

I don't think this is normal behavior since a hydraulic system is closed. Can I epoxy this closed or JB Weld it, or am I screwed to replace this M/C?
