If you have replaced any of the parts on your ABS/master cylinder, I would be interested in getting the bad parts. <P>My intent is to test accumulators and pressure switches. The easiest way to make a tester would be with an old/bad motor,pump assembly. I am talking with hydraulic people and we can make/buy a hand pump to pressureize the unit. A gage would be added to check pressure. This may be an option to replacing parts that we "think" are bad. <P>Let me know what you have and I will pay shipping to get parts to "play" with<P>------------------<BR>Barney Eaton Reatta technical advisor for BCA and keeper of the Reatta database.
