I need to use a Dot 3 brake fluid because the compressibility characteristics of Dot 4 and 5.1 are different and it messes up the ABS. Wildwoods 570 racing Dot 3 brake fluid handles high temperatures, but I don't know for how long. Castrol LMA Dot 3/4 sounds good if you know what LMA means: Low Moisture Activity. I'd also like to know the specs for Autozone Super Duty Dot 3 Brake Fluid. So I want to know the DOT 3 (or compatible) brake fluid which will need to be bleed of flushed the least.
