The number of vehicles with ABS (Anti-lock Brake System) has been increasing strongly lately and in 2014 Brazil will have 100% of all manufactured vehicles with this system. Therefore, South America is passing through a process similar to the one that developed countries already passed, where all manufactured vehicles had the ABS included. This process of improving the vehicle safety through the use of the vehicle brakes has a lot to be developed in the South America and especially in Brazil, once the developed countries have stability control systems such as the ESP already included in all new manufactured vehicles. The aim of this article is to study the Brazilian's driving behavior under specific braking situations. It is proposed a testing and analysis methodology from vehicle data acquisition. The purpose of this methodology is to minimize the external effects and the effects that might disturb the data analysis from braking events acquisition, such as deceleration, pedal force, locking pressure, etc. As the South America is a growing market in the use of the ABS, it aims in understand the local market needs to generate new information to the local drivers' more effective usage of the ABS, and thus safer. The better understanding of the market may improve the system development, optimizing its application by the understanding of the drivers' behavior.
