Halo P1 is developed by Orthene, renowned brake fluid experts with over 48 years experience in creating high-performance brake fluids for both road and racing.

Eighteen months of extensive research with professional race teams, combined with Orthene's unique expertise as the largest specialist brake fluid manufacturer in the world, led to the launch of the Halo By Orthene brand and Halo P1 specialist racing brake fluid in 2024.

With the highest boiling point in the world and unique Fade Resistant Technology™, Halo P1 has extremely low compressibility and delivers a more consistent pedal feel across a wide temperature range - giving drivers the confidence that their brake fluid will perform from the first lap, to the last.


Purity
Crafted using the purest methyl borate ester which goes through a proprietary multi- step purification process before beginning the reaction process. Impurities degrade performance, reduce boiling point, and create instability at high temperatures. This is why we remove them.

Polarity
Halo P1 is highly polar. Polar molecules don’t like to occupy the same space, and so resist being compressed. Which is essential in racing conditions.

Extremely low compressibility
A high boiling point of 646°F / 341 °C and unique 

Fade Resistant Technology™ makes Halo P1 extremely incompressible across a wise temperature range which supports a very stable pedal feel throughout the race.

Lubricity
Lubricity at high temperatures protects and maintains the brake system at high temperatures. Halo P1 has special additives reacted into the backbone of the product to ensure the highest lubricity even at high temperature. This is particularly important for ABS systems and for consistent caliper roll-back.
