An Opel Agila passenger car was used for the research, on which various brake system faults were simulated. It was determined which of the simulated faults could be clearly identified on a roller brake tester and which could not. General ranges of braking force changes caused by individual faults were also provided.All vehicles in operation wear out, and this applies to all components from which they are built. To be able to accurately determine which of them is responsible for the vehicle’s malfunction, a diagnostic test of the vehicle must be performed. The speed and accuracy of the diagnosis, which allows for the elimination of the fault, play an important role for both the safety of the vehicle’s movement and the people traveling in it. A quick diagnosis can be obtained by performing a non-invasive test. Such a test is the examination of the brake system on a roller brake tester using the quasi-static method. Every car undergoes such a test at least once a year during a periodic technical inspection. It is, therefore, an opportunity to verify the correct functioning of individual vehicle systems. One of the most important systems that has a direct impact on road safety is the brake system. The article attempts to answer the question of whether, based on the data obtained during such a test (…)
