This task evaluated the compatibility of Army Silicone Brake Fluid MIL-PRF-46176B, DOT V, SAE J 1705 with a commercial Heavy Duty Anti-Lock brake system. There have been reports of possible high temperature degradation of the MIL-PRF-46176B, DOT V, brake fluid that have led to deposition and filter plugging, and subsequent braking system filter collapse. Testing of a Hydraulic Power Brake system with MIL-PRF-46176 silicone brake fluid confirmed a manufacturer claim that the fluid was incompatible with the power brake hardware. Testing with a DOT III brake fluid did not reveal any evidence of particulate formation.
