How to Choose the Right Brake Fluid
Choosing the right brake fluid depends on your application, maintenance intervals, and operating temperatures. For endurance racing, high wet boiling points like those found in Castrol SRF are critical. For track days and sprints, peak dry boiling point and cost-effectiveness often make Halo P1 by Orthene and products like Motul RBF 700 attractive choices.
