Has anyone actually flushed an ABS unit on a non-integrated, non-servo 2000 LT??
If so, could you possibly post a step by step procedure on what tools (syringes??) are needed and how this is done.
If someone will post clear step by step instructions on how this is done , I will do it AND take pictures for a possible Hall of Wisdom archive.
Seems to me that if this procedure that costs nothing more than some time and the cost of a bottle of Dot 4, and has the potential to save everyone with an indication of ABS unit failure....that does it $3000...........that it should be a well documented procedure.
Get me started and I will take the pics and lets see if we can's get a clear DIY tutorial put together.

One of the reasons you probably don't see any information on non integrated ABS flush bleeding is because there isn't anything special about it. Fluid in the reservior, open the bleeder screw and flush.
Dan Martin is correct in that the fluid travels through the ABS unit and down to the calipers. However, there are two bleeder screws on the ABS unit. One for the front and one for the rear. Bleed those first until you get clear fluid and then do the calipers. (I bled the calipers first and then went to the ABS unit and was rather surprised at the amount of "garbage" that came out even though the caliper fluid was already flushed clear.)
1. Take your time it isn't difficult.
2. Remember that brake fluid kills paint. Keep things covered up.
3. Keep the reserviors full so that you don't take in any air. If you do, just bleed it out. Takes a little longer is all. No harm done.
4. You don't have to remove the handlebar covers to level the reserviors (as stated in the manual) If you turn the bars full left for the front brake reservior it makes it level enough to get the job done. (See 1 and 2 above)
5. If you remove enough body work to get the left and right side battery covers off, the ABS unit and the rear brake reservior are in the open making it much easier to access those parts.
The tips above are under the assumption that you have bled brakes before and understand the basics. I guess if you have more questions just ask.
Good Luck. It's easier than it looks.
