ABS Unit Leak

ABS Unit Leak
So I'm slowly leaking brake fluid onto my driver's side fender of my car below the ABS unit, joy! Before I have to take it apart and troubleshoot it, does anyone, A: know what might be the culprit or have seen this before? and B: have any diagrams or information on the unit?
My car is an 89 745 Turbo

So, it's been a few months and no one has posted anything about bleeding the ABS system. I'm still looking for ideas, now the breaks have gotten worse (the pedal goes to the floor) and the clutch pedal also lowers over time (it kills cruise control). It looks like I have a good bit of plumbing to do. I think I need to rebuild both master cylinders. While I'm at it I might replace the flexible hydraulic lines, I'm thinking steel braided. Anyway, any suggestions on the ABS or master cylinders (rebuild, new or something else) would be great. Also, one last thought, the clutch slave cylinder could be leaking, but I don't know if it's likely or not (I need to get under the car and look for leaks but it's over 2000 miles away for now). So I'm looking to see if anyone has had some experience with this as well. Thanks.

The pressure bleeder is the ONLY way to go. The 240's have a very specific order the brakes must be bled in. It's not your typical setup, some of the calipers have 2-3 bleeders each.If you don't follow the correct sequence it won't purge all the air. And as far as I know, the only way to bleed ABS is with a pressure bleeder.
Now that I look at my Bentley book, ABS bleed sequence is as follows. Left rear, right rear, left front, right front. This contradicts general procedure which would be Right rear, left rear, left front, right front. "I.E. start from the farthest point from the master cylinder, and work towards it"....good luck hope this helps BUY A BENTLEY MANUAL THEY'RE FANTASTIC!!
