Brake fluids offer large temperature ranges of fluidity for dynamic braking performance. Modern brake fluids combine increased boiling points in “dry” (new fluid) and “wet” (used fluid after few years in vehicle) condition with reduced cold viscosities to achieve reduced vapor lock risks with more dynamic pressure build up performance. However, reduced lubrication performance risks have been observed within the development of first modern brake fluids. Since sealing rings in braking systems are “lubricated” by brake fluid and form tribo-systems, lubrication performance of the brake fluid is essential in vehicle application and should be part of brake fluid standardization. Automated driving and increasing noise requests due to electrification will further increase tribological requests for the pressure medium. To avoid future wear and noise problems, it is essential to develop and validate appropriate test methods to assess and prescribe lubrication performance of brake fluids. Therefore, the project TriNoWe - publically funded by the Federal Ministry for Economic Affairs and Energy (BMWi)- did identify the impact parameters, stress conditions and their dependencies based on a deep tribo-system analysis to develop appropriate test methods. A valid noise lab test method - reflecting the product results - was developed as DIN 51384-5. The final round robin test noise performed within the SAE&ISO task force brake fluid lubrication does show consistent and comparable results of already seven participants. A new EPDM disc holder - showing significantly reduced result deviation – is expected to improve observed differences in fluid differentiation and result levels. For wear, a similar test method is still in work to be published as DIN 51834-6.
