You might want to try to determine exactly where it's leaking from, first.
I've seen the banjo fitting leak. You snug them up just a bit and the leak stops.
I've seen the caliper fitting start leaking. You can try snugging it as well or just re-Teflon tape the fitting and reinstall and bleed.
and here's a strange one, chopper brakes "sometimes" are hard to bleed and completely remove all of the air out of the system due to their long brake lines.
"IF" the brakes are bled "improperly", and air remains within the system. I've seen them leak around the piston seals & boots in spot about the size of a quarter, during the overnight period.
If this is the case re-bleed, taking the following necessary measures that will allow the fluid & "air" to escape, but "NOT" allowing any air to re-enter the system during the return stroke of the bleeding process. This is easy to accomplish by attaching one end of piece of rubber tubing to the bleeder valve nipple. Place the other end of the rubber tube into the bottom of the can, in the fluid itself, of brake fluid "after" you've filled the brake reservoir. Then bleed system like normal, and slowly taking your time, until no more air bubbles are returning into the brake fluid reservoir. :2thumbs: Then button everything up, clean thoroughly and continue to watch for any signs of a leak.
Just a little info, hope it helps. :2thumbs:
