The Ford HD fluid is very good fluid especially for the money, though, they have recently changed the packaging, and I haven't used any of the stuff in the new package. I have been using ATE Super blue in the contour for awhile now, and I've been very happy with it.
In our race cars, we've been running the Motul 600 which is awesome in all but the most extreme cases, where nothing short of Castrol SRF is going to work.
bigmoney, proper brake servicing is critical, as is using at least decent fluid when doing the servicing. If you want to stay super cheap, go with the Ford HD fluid; then hunt for the Super Blue (which really isn't that hard to find and isn't that expensive either) then after that you would be looking at a Motul 600 type fluid.
