Why would a bleed nipple leak, when tightened.

almost 100% of the time it stops.

Just what you want from your brakes of course

Pah,Wull never bothers with those brake thingies,they only slow him down.

You should really pull that bleed screw out and make sure the seat, taper, thread and bore are clean and intact. I'd want to know or at least to be sure that it's ok, things don't fix themselves.

Seeing as the brakes have been cable tied a few times an no more issues, all I can thing that I didn't tighten the nipple the first time.

After bleeding brakes you sometimes have fluid left within the thread area that works its way out, the thread area is tapered so some fluid gets trapped in there and seeps out, I’ve had this quite a few times, all you do monitor it for a few days and almost 100% of the time it stops.

Monitoring every day, some times twice.
