Default What do you think is causing this brake fluid leak? (near reservoir)

I had a new front-end put on my bike last weak, and every time I drive it (and pump the frunt brake) brake fluid drips from under the brake handle. Any guidance would be greatly appreciated.

Man if its coming out of the banyo fitting.... when fluid can get out, means that air can get in.
You could try crimping it tighter & hopefully stop further leakage, even then I recommend bleeding the system again. If that does not fix it, then your going to have to have the thing apart & redo it all again with new washers.

Can you post a pic of the banjo? I am leaning towards the seals around the piston have failed though.

The pics you posted arent as revealing as I would like, but my guess is that the banjo washers may be leaking. If the shop used the aluminum washers most are nowadays then it may not have sealed properly and is letting out fluid and sucking air in.I always use copper washers as they seem to seal better. Or it may be a leaking plunger seal. I have seen both happenbefore. Maybe a couple better pics?
