leaking abs module I was attempting to bleed my brakes when I used the motive power brake bleeder to test for leaks. I pumped it to 10psi when i noticed a leak falling on my garage floor (after a few minutes). I kept looking and looking at the fittings and as far as I could tell, they were bone dry. I crawled underneath to see what was going on and could see a drip coming from the bracket where the abs module sits on. Unless my eyes are playing tricks on me....it seems to be coming from the bottom of the abs module. Does this make any sense at all? Has this ever happened to anyone before? Could it be that I shouldn't have pressurized the system?

Still have not found one that will do the pump. Everybody seems able to do the electronics part. I have encountered a similar problem and since GM no longer lists the 4ch replacement pump its off to ebay for few renaming used ones. once those go away guess its time to throw the car away
Or you could just delete the abs unit and add a proportioning valve. We drove cars for years without antilock breaks. It's not a big deal
