Brake Fluid

The Halo P1 brake fluid is formulated using the purest form of methyl borate ester which gives the fluid an extremely high polarity and ensures low compressibility across a wide temperature range and delivers a more consistent pedal feel over an entire race distance.
A product with characteristics that place it on another level of performance.

4 point of absolute excellence:

1 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.

2 Highest boiling point
The purity of Halo P1 allows it to reach an extremely high boiling point of 646°F / 341°C. This means that Halo P1 is able to achieve and maintain a consistent performance up to the highest racing temperatures.

3 Low compressibility
Featuring Fade Resistant Technology™, Halo P1 is a highly polar fluid. Polar molecules don't like to occupy the same space, and so resist being compressed. This makes Halo P1 extremely incompressible across a wide temperature range which gives a very stable pedal feel throughout the race.

4 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.

The bottle
The Halo P1 bottle has been selected through a rigorous selection process, testing and chemical analysis to ensure that Halo P1 is delivered in the ultimate racing brake fluid bottle.
Manufactured from aluminium 1050A and 1070A, this packaging provides high impact, tear and chemical resistance while also guaranteeing a 100% UV barrier.

PAGID RACING’s High Performance Racing Brake Fluid has been specially formulated for racing applications, where braking systems consistently operate at very high temperatures.
The typical dry boiling point of 330°C (626°F) is extremely high and guarantees maximum safety against vapor lock.
In addition to guarding against vapor lock, Pagid RBF High Performance Racing Brake Fluid maintains its excellent viscosity, lubricity and compressibility performance at extreme temperatures, helping to maintain braking system reliability and performance.

Factory R DOT 5.1 is AP Racing’s high performance non silicone based brake and clutch fluid.§

Factory R DOT 5.1 is recommended for use in the hydraulic brake and clutch systems of all cars, for which a non petroleum based fluid is specified.
Suitable for high performance applications including vehicles fitted with ABS and ESP, is suitable for road and track day use.

AP Racing Radi-CAL R2 fluid has a dry boiling point exceeding 300°C and has been developed for racing applications where high temperatures are being experienced, e.g. when using carbon discs and the ultimate in brake fluid performance is required.

 

It should be noted that before using 600 fluid, any existing brake fluid should be drained completely from the brake system.
The system should be thoroughly purged with new 600 and can be filled completely with new 600 fluid.

Radi-CAL™ R4 has been designed to perform better than any other product at the extremes of heavy duty braking performance in the top levels of racing.

With the highest dry boiling point of any racing brake fluid currently available, at 340°C (644°F), R4 stands alone.

With outstanding resistance to vapour lock / pedal fade under the most exacting conditions. A higher vapour lock point means a firmer brake pedal at the extremes of brake temperature. Enhanced lubricity, means this fluid is an even better lubricant than PRF660 itself a market leader. This helps the life of the metal moving parts of the brake system and increases system efficiency.

Note:
R4 can be mixed with DOT3 and DOT4 racing brake fluids but for maximum product performance the brake system should be thoroughly purged with R4 fluid.
