A prior study with MIL-PRF-46176 silicone brake fluid and SAE J1703 DOT 3 brake fluid in a hydraulic power brake system revealed deposits only with the silicone brake fluid after 20,000-cycles of testing. These results are published in Interim Report TFLRF no. 445. The overall conclusion is that the root cause of deposit buildup in the system reservoir, that caused testing with silicone brake fluid to halt in FY13, is due to formation of a thin Styrene-Butadiene (SBR) elastomer residue on the servo valves. This conclusion has been substantiated through a number of conclusions from static soak and dynamic seal tests, followed by a series of conclusions from physical and chemical characterization tests. Increased wear seen with the silicone brake fluid on brake system parts was substantiated by laboratory bench wear tests of the brake fluids.
