Abstract :Vehicles with different weights are subjected to vehicle brake tests at vehicle inspection stations at regular intervals due to government regulations. Safety and efficacy of vehicle roller brake testers are important for reliable inspections at vehicle inspection stations. Rolling-element bearing used in vehicle roller brake tester is the main cause of problems. In this study, total energy, mean, variance, cross-correlation and correlation coefficient values of median filtered signals were calculated based on the signals obtained using real-time vibration measurement data. With this study, it has been confirmed that, over time, the values acquired by all the methods go up and exceed the thresholds identified. Proposed majority rule based combined excession of these thresholds expresses that the rolling-element bearing used in a vehicle roller brake tester is too close to a mechanical fault.
