Design of brake bleeding tool for four wheeled vehicles using pneumatic system

Abstract

Used bottles and pipes are the tools that have been utilized in the manual process of bleeding. There are several weaknesses in using these tools for bleeding, thus there is a need to create a new design using the existing tools. With the used bottles and pipes, a great amount of energy is needed to pump the brake pedal, and two people are needed for the job. Furthermore, the use of used pipes and bottles is less efficient because it requires a longer time to complete the bleeding process. Upon evaluating this issue, a tool to complete the bleeding process more effectively and efficiently is needed. Thus, the tool to minimize the need of more mechanics in the bleeding process is important. For this, the brake bleeding tool for 4 wheeled vehicles using the pneumatic system is designed. This tool utilize the vacuum resulted from the T junction, and with it, an effective and efficient bleeding process is attained. It is especially efficient in terms of manpower because one person is enough to finish the job, and the bleeding process time is more efficient. Based on the test conducted, the average time needed to manually bleed a vehicle is 542 seconds. As for the brake bleeding tool for 4 wheeled vehicles using the pneumatic system, the average time needed is 389 seconds. The test results show that the design created is able to accelerate the bleeding process by 28,2% faster than the manual method.
