STORAGE STABILITY OF BRAKE FLUIDS
Abstract
The object of this study was to investigate the stability of corrosion inhibiting systems found in brake fluids approved under Federal Specification VV-H-910a after extended storage of the fluids in steel and glass containers. Corrosion and oxidation stability tests outlined in VV-H910a were conducted on twenty-two approved fluids after 2 1/2 years storage in 5-gallon steel containers and on eight approved fluids after 5 years storage in 1-gallon glass containers. In all tests conducted there was evidence of inhibitor instability or depletion. Sixteen of the twenty-two fluids stored in cans and five of the eight fluids stored in glass failed to meet minimum requirements of specification VV-H-910a. Nine of the fluids stored in cans and three of the fluids stored in glass also failed the more relaxed requirements of Society of Automotive Engineers Specification, 70R1, which is the controlling specification of the Federal Register.
