ditto: yes. You can flush it yourself, but the antilock portion will not get clean juice if you do... unless you do it all around and then when it's raining or such make the antilock system do some work. You'll know when the system is working Then redo all the wheels... I'd wait to redo them a couple of weeks and make sure you excercise those antilock systems in between.
In my opinion, if you have a grease monkey do it, they may not do the antilock system as they would need the right codes and the right equipement to flush the antilock portion... My bet would be they would SAY they did 'em and would just ignore it.
The antilock parts are VERY expensive to replace, so clean brake fluid is the only preventive measure. I do mine every year, flush all the old stuff out of the main parts and let nature kick the new fluid into the antilock portion when it snows or rains.
