RESUMO

Due to the necessity of launching new products and the introduction of new technologies in more and more competitive times, automobile companies develop methods in order to get the approval of its products aiming at reducing the development time and keep meeting the quality requirements. Thus, in the automobile sector test tracks are developed in order to simulate the vehicle applications main features aiming at anticipating and analyzing the reliability results of components before launching the product in the market. In order to check the effectiveness of the results obtained during the simulation test, it is necessary to compare them with warranty data. However, there are components which are considered wear items and which aren t covered by the automaker warranty making it difficult the comparison with the results obtained in the simulation tests. Thus, in order to check the effectiveness of the results obtained through a simulation to brake pads it was selected samples from many vehicle users right after its launch and it was monitored for the wear of brake pads, aiming at obtaining reliability data in real application. The objective of this work is compare information obtained in both tests, using the reliability concepts. The developed methodology can be applied to validate the tests to wear items, during the development of new products, mainly vehicles
