The Halo P1 by Orthene brake fluid is the latest in high end brake fluids, suitable for the highest brake temperatures. Halo P1 is formulated to use a very pure form of methyl borate ester, this gives the brake fluid a high polarity which reduces the compression of the fluid (even at very high temperatures). The reduction in compression means that the driver has a better, more consistent, pedal feel throughout pedal travel and when the brakes reach higher temperatures.
Halo P1 brake fluid has a dry boiling point of 341°C (646°F) and a wet boiling point of 206°C (403°F).
Orthene's Halo P1 brake fluid is suitable for high end motorsport (especially longer races) and is a single 600ml bottle.
