What brake fluid can I use with Wilwood brakes?

Here's all the different boiling points. There is not one that boils at 570*.

Not in a DOT standard, no. In a custom formulation, yes. How long does it maintain that BP? Dunno, depends on ambient humidity and service conditions.
Castrol LMA is my own choice for brake fluid. http://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/0027D9455250B6C780257AA900537025/$File/Castrol_Brake_Fluid_DOT_4_03742.pdf

I'm going to purge the Bronco of it's silicone fluid. It has two seized calipers and all of the rest of the system is normal. There have been cases where silicone has caused seal swelling when it should have been compatible. Pending evidence to the contrary that is what I'm blaming this problem on.
