At ATC, tests on the two water intolerant silicone fluidswere discontinued because of possible (crystallization at low temperatures and were replacedmidway through the first year with fluids having improved low-temperature properties Thesefluids were superior to the N11-11013910 arctic brake fluid after one year's service.

[it I1967. because of the success of silicone fluids iii hyd raulic applications, makersof these fluids became interested lin developing a single all-purpose lid to overcomethe# water -wnsitiv~ih~ of current fluidIs as well as to p~rovidet all-weather and] preservativeprope-rties. The producers were encouraged to develop) such a fluid since it wouldreduce miaintenane and] logistics costs substantially by providing increased brake sys-

Nears, dieficiencies such as poor lubrication properties and rubiber Incompatibilitywhichi shiowed up in laboratory testin wrlesndy(t-e incorporation of small
amounts of additives to the fluidls. Laboratory evaluation, including stroking testsbased on SAE specitications and storage tests for packaging and preservative properties,estaldislied that a silicone fluid could bx- formnulawcd tu pros ide heavy-duty and arctic-type performance and the preservative properties required by the current brake fluidsand packaging fluid. The remaining question of suitability under all operating condi-tions required the( cond~uct of a field test. During March and April 1973, therefore.tests were initiated( to obtain experience with silicone! fluids in operational vehicles
Three silicone- fluids (two water-intolerant and one water-tolerant) and a conven-tional specification fluid were installed in the brake systems of vehicles operated byArni> units in three areas representing climatic extremes: tropical (Tropic Test Center,Panama Canal Zone); extreme cold (Arctic Test C;enter. Fort Greeley, Alaska); ariddesert (Yuma Proving (;round, A.rizona).
The first year inspection was covered in USAMERDC Report 2132.* This por-tion of the test showed that the silicone brake fluids will equal or exceed the perfor-mance obtained from current specification fluids. The most significant improvementwas found in Panama where nume-rous malfunctions due to corrosion occurred withbrake syste~1s using the specification fluid. There were no malfunctions with the sili-cone brake fluids.

Tlhiree siliconie fluid,, (two water-intolerant an(] otie water-tolerant) and a conl-%eiitional specifiration fluidl (V V -B680) were used in Panama and Yumna. These. sili-cones were used iicitiall% in \laska. lestinig on tile water-int~1erant. fluids was dis-c-ontinuedl idw a% through the teAt, lie~ever, because of possible crystallization atteniperatures below ininius 46'C (5f 0 '), aiid two new silicones with improved low-temiperature properties were substituited aii(l compared to) coniventional NIIL-l 1-13910arctic b~rake fluide.
For these tests, new brake cylincder sets were packaged with fluid in the labora-ton. and shipped with new brake hoses to the appropriate area for installation on\1 15 1, "4-tori cargo vehicles and NI 715. I'/4-ton vehicles. After one year, half thecylinders from Paniama and Yumia were torn (]owui on sitce and examined for conditionI of the mectal parts and rubber compoundls atiol for appearance of the fluid. Samples ofthe fluids were sent back to the laboratory. The cylinders were then reinstalled andhrouight back to level with fresh fluid, and the vehicles were returned to operationl.I Cylinders of the other vehicles were left undisturbed. After two years' operation allcylindlers, hoses, anol samples of the fluid were returned to the laboratory for finale~valuation. In Alaska, all cvlinders were returned for examination after one vear'soperation. In addition to visual examination of the fluids, water pick-up wasdetermined 1y the Karl Fisher Method.
1l1. DISCUSSION
In Panama (Table! 1), three oif the four vehicles using the VV-13-680 fluid com-pleted the second year of operation without a brake malfunction (numerous failuresoccurred duing the first year) even though the cylinders were severely corroded. TIhe
* fourth vehicle was reported missing in February 1975, and no data are available.* During examination of the brake parts, a srong odor of gasoline and swelling of the

Fluid performance was comparable to the Panama portion of the test.Visual inspection andl pertinent data are shown in Table 2.I ~ At Fort G;reeley, Alaska, the vehicle containing NllL-lI1-139 10, Arctic Brake Fluid,showed heavy corrosion of the wheel cylinders and scoring of the pistons. All thevehicles with the water-intolerant silicones gave comparable results, showing only slightstain of the cylinders and, with the exception of one vehicle using the D.C. fluid,showed no piston scoring (Table 3).

'[lis program has shio%u that silicone b~rake fluid will equal or exceed fte per-torniaiice obtaiiiet fromt current specification fluids in conventional hydraulic brakesystems. The water-intoleratit silicones show considerably less corrosion titan eitherflit- con'.ntiouial fluids or fte- water-tolerant silicone fluid after the two-year period.After onec year in fte arctic, both fte water-Intolerant and flit! water-tolerant siliconeswere coinparabile iii perfornmance.
Basedl on this study and previous laboratory evaluations, silicone brake fluids havedlemonstrated their potential for uts( in the bulk of fte Army fleet, which is composedof vehicles under I10,000) pounds gross weight aiid equipped with conventional hy-draulic brake systems.
During this test period, however, laboratory tests conducted by a brake partsmanufacturer indicated a potential problem with silicone fluids in vacuum over hydrau-lie brake systems used on vehicles of over 10,000 pounds gross weight. Since the Armyfleet includes vehicles with this type of hydraulic brake system, further studies and
tests are being conducted to resolve the problem.
Thue swelling of the rubber cups in the master cylinders of vehicles equipped withthe deep-water fording kit can produce brake system failures regardless of thle fluidused.
