Hydraulic braking systems prevail as the most popular type of modernized braking application. This braking system is most efficient due to the controlled use of braking fluid. Supply line failures and damaged oil tanks deteriorate the functionality of the system, which inherently leads to accidents with a loss of control. This research aims to develop an alternative fluid supply line to the master cylinder for cases of emergency. Advantages such as less space, automated operation, and ease of manufacturing and assembling have been identified as key promoters for this development. A gravitational means of fluid transportation is encouraged. When the master cylinder chamber requires braking fluid, the main fluid reserve supplies theamount needed. With this alternative supply, even if the main supply system fails, the master cylinder will receive enough fluid oil when needed. This system will be helpful in emergencies until drivers can find a repair station to fix the braking system failure. The device was formulated with the minimum number of components necessary, namely, a level sensor, a non-return valve, a reserve tank, and a few fluid lines. The application of a prototype to 25 selected vehicles highlighted that 30% of the samples were able to utilize the fluid management system in an appropriate manner. Its drawbacks include the misalignment of the flow systems and an inadequate supply to ignite the engines. In addressing these limitations, a pump can be incorporated to undermine the issues of reserve tanks. Thus, brake fluid level management rectifies the drawbacks of a conventional setup while minimizing emergencies.
