the ford Dot4 HD stuff is way over rated.
also, i was unaware of any dot3 that were "HD" let alone rated at 550°F. the dot system of brake fluid relates to it's wet and dry boiling points, what it's made from and if it is able to be used with ABS or not. most dot3s are not recommended or should not be used at all in ABS equiped cars, that is why dot4 was made which typically has a fairly higher wet and dry boiling point aswell. dot5 is silicone based, extreme duty fluid and not really suited for anything but race brake systems as the silicone fluid is not good for the rubber seals in a standard barke system. dot5.1 and the new dot6 stuff are extreme high temp fluids designed with racing in mind but to be usable on street cars aswell, Dot6 is ABS safe in certain cars, not all i believe. the dot5.1 and dot 6 also come with very high price tags.
i have boiled the Ford Dot4 HD fluid as have most of the people i raced with, running the same setups that are doing fine witht he ATE stuff. infact the time i lost my brakes from boiling the fluid was with the ford HD fluid which was only 4 weeks old after i did the TCE big brake upgrade.
the Ford dot4 HD fluid out here is like $12-15cnd for a 12oz bottle... for a full brake flush which requires about 600-850mls, it's up in the same price range. out here the ATE fluid can be found in certain places like $24-30cnd...
