The aim of this research was to analyze the thermal behavior of organic, semi-metallic and ceramic brake pads as a function of the stopping distance according to international standards. The chemical formulation of each of them is identified by micrography. The experimentation is carried out from the selection of the vehicle of the categories M1, N1. It is based on statistics from the AEADE and the selection of marketable brake pads in the Ecuadorian market that comply with the INEN 2185 Regulation. These pads are subjected to braking tests, the procedure and the selection of the necessary parameters for the braking tests are based on the ECE 13 - H regulation, verifying the minimum standards that are detailed there. The data is collected by means of a pyrometer and stored for statistical analysis to determine the behavior of the temperature generated in the brake pads with the different treatments. A variation of 34.49 °C in the organic type, 48.64 °C in the semi-metallic type and 52.98 °C in the ceramic was obtained. To validate the experiment, a multiple comparison analysis is performed using ADEVA to the temperature and stopping distance data of the treatments. The result is a probability ≤ 0.0001 for the validation of the null hypothesis. Thus, the alternative hypothesis was affirmed, the data was reliable, and the study validated. It is concluded that ceramic-type pads offer better performance with a temperature of 78.92 °C when braking at a braking speed of 50 km/h and 127.56 °C at a braking speed of 100 km/h, it was obtained an efficient braking distance at different initial braking speeds. It is recommending the use of ceramic type pads that guarantee the safety of the vehicle occupants.
