An analytical and experimental program was conducted to design a long life brake system for passenger vehicles which would have a doubled period between required servicing in comparison to conventional systems. The design approach was constrained to be compatible with existing vehicle configurations and not to differ radically in braking principle. Formal study objectives were to analyze the state-of-the-art of hydraulic brake systems, to identify system assembly and/or component design requirements which will assure a significant increase in service life without maintenance and repairs, without affecting safety, performance or fuel economy; to develop techniques which can be utilized objectively in quantifying system durability and recommened procedures suitable for use in compliance testing. Service life was found initially to be defined by friction pair maintenance in the 30000 - 40000 mile range. Subsequent servicing requirements were necessitated by a number of mechanisms derived in large part by fluid degradation, metal corrosion, and rubber deterioration. (DePo)
