My independent guy was not interested in this job for some reason. So I took it to my dealer (who is very good but expensive). The allowed me to bring my own part ($40 from an e bay seller as the local pick & pull gets $80 for an abs pump???) They did the work yesterday along with a bad control arm (plus alignment) for inspection. Now $600 later the car lives to fight another day (or hopefully a year longer). FYI the dealer charge for labor on this ABS pump repair alone was $225.

The dealer tech said he only ever saw one of these pumps bad back when the 850's were new and the pump was leaking. Other than that he never replaced one before. So it is a rare repair even 18 years after the car was built. The good news is used parts seem to be a good way to save on the cost. FYI, the 850's have two types of ABS pumps. These with TRACS and those W/O. I also believe later 1995 the pumps change to a square shaped unit whereas the older pumps look more like a black cylinder. You have to match the units correctly. I'm no expert in this repair so double check your part number for compatibility at the dealer.

I hope this helps someone if they get no fluid when trying to bleed their 850 brakes.
