There is brake fluid coming out of the ABS brake block located in front and forward and below the master cylinder. Fluid is leaking out of one of the unused nipples facing firewall. It is a constant drip requiring brake fluid to be added to the brake reservoir three times a week. Fluid will leak down on ABS block bracket, run forward to the electrical connections on the control box and electric motor, down to the frame, down to a hose and then to the ground. All a bad fire situation at any time. Any help or ideas?

Sounds like one of the block bleeders is leaking. It could be a simple fix if the bleeder is loose, simply remove it, clean out the port and install a new bleeder. If it is due to the bleeder being rusted out, I would replace the block because it is likely that you will not get the bleeder to back out.
