I've never had to deal with ABS problems myself, thankfully.  But I'll 
share a weird one that may be of use or just make you go "WTF".  Brother 
in-law's minivan (the Ford/Nissan thing, whatever that was called) 
developed ABS weirdness on a road trip to our place.  ABS pump kicking 
in at odd times making dangerously reduced braking.  Turned out the 
toothed sensor ring on the end of a front CV axle was loose and 
literally spinning freely around on the thing!  Thus confusing the hell 
out of the ABS computer.

Sounds like 1 in a mill, but maybe something to check.
