Resumen
The objective of this study was to analyze the braking efficiency of a sedan-type vehicle with
an ABS, using two brands of brake pads based on their working temperature. An electronic
temperature monitoring system was created for a Chevrolet Sail vehicle year 2018 to perform
the analysis. An infrared sensor for capturing temperature was adapted to the brake calipers
in the front tires of the vehicle for the braking system. These sensors were placed 5mm away
from the brake pads. The obtained data through the infrared temperature sensors were
processed in real-time employing an Arduino card and then stored in a computer. The
investigation was based on the brake system, which involved thermodynamic phenomena
caused by the friction between the disc and the brake pads since it does not have a stable
behavior. It was observed how the pads temperature influences the braking efficiency of the
car with the implementation of the monitoring system. The study used three samples from
two brands of brake pads: DBL and BREAK PACK. To obtain brake pad temperature data,
five follow-up tests were performed on each selected sample, these tests were performed by
ISO 21944:2007. From the obtained results, it can be seen that the changes in temperature of
the BREAK PACK brand of brake pads dissipate heat in a better way, thus improving braking
efficiency, which demonstrates the difference in marketing costs. It is important to point out
that before putting the system into operation, it must be optimally calibrated to avoid possible
inconsistencies in data collection.
