yes, higher boiling point, but also as I understand it there are some brake fluids out there that have a better chemical structure to avoid piston freezing on the calipers. The Calipers themselves are aluminum, and the pistons are stainless steel. Oxidation can occur between the piston wall and caliper...hence using certain chemical compounds and needing a higher boiling point!
