• Unique proprietary formulation
• Designed for the most demanding motor racing applications
• Race only formulation
• Highest temperature resistance. Lowest compressibility

Halo P1 uses Methyl glycol ethers because they have the highest polarity of the glycol ether series. Molecules of P1 have polarity or an electrical charge. This means that if compression is applied to P1 the charge of the molecules acts to keep them apart – low compressibility. This action acts to transfer to force between the molecules very efficiently. 

This leads to the outstanding properties of P1 and maximum connection between the driver and the brake calipers. The compressibility of P1 is very stable over a wide temperature range and compared with other racing brake fluids there is very little change in the hydraulic  properties from 55 ° F to 555 ° F

The lubricity of P1 is amongst the highest of any racing brake fluid and is maintained at very high temperatures. . High lubricity between rubber to metal and metal to metal. 

This is achieved by unique set of additives which are produced by chemical reaction and ensures very consistent performance in areas such as caliper piston roll back and protection of the brake system even under extreme loading situations.
