5.3. Experimental Process In addition to requiring a simulation process, the experiment process needed. The real situation provides from the simulation process overview can be explained for the next testing. One of that is to use the experiment process on the testbed. Using a testbed, you will get a controlled testing system. Control of this test is needed to obtain data following the objectives of the study. Wang (2019) researched experiments on disk brakes commonly used by trains. The effect of heat generated by the braking process could affect the condition of the braking components used. The results show that the experimental process will give result in changes in the structure of the disk used shown in Fig. 8.

6. Conclusions The braking system is one of the most crucial driving safety guarantees. In general, braking failures occur due to mechanical damage to the braking component. One that often happens is damaged disc brakes, and brake shoes are used. Damage to the disk brake usually occurs because of the risk of the design used, failing due to cracking. As for brake shoes, a lot of damage occurs due to the use of inappropriate material. Braking system failure due to component damage will be hazardous to cause an accident. The solution used to improve braking performance is used to modify the design of the disc or brake shoes. In doing optimization, braking needs analysis needs to be done; the calculations made can also be helped by the modeling or simulation process. An experimental process can also support the simulation process. With the support of the results of experiments and simulations obtained, it will be able to provide a general description of the use of changing these parameters. In the future research can be conducted on the application of appropriate materials using designs that can give excellent performance.
