This paper refers to the impact of the design of passenger vehicle braking systems on their durability. The braking system of a passenger vehicle has to meet the criteria of the shortest possible stopping distance, reliability, stability and maneuverability during braking. Traffic safety is one of the most serious problems nowadays. Every day there are numerous traffic accidents, which often end with tragic consequences, i.e. the loss of human lives. In order to protect human lives, traffic safety should be raised to the highest possible level. With the aim to increase the safety of the road transport and of transportation in general, modern technologies, which enable the decrease of the traffic accidents, have been developed. That is mostly related to the system which controls vehicle stability and braking, which represent the main cause of the most accidents. Modern vehicles are equipped with the electronic system, which represents important tool in critical situations by assisting the driver to avoid the accident. Built in computer system in the vehicle receives the data on road conditions, driving mode, climate conditions and other potential risks, based on the sensor reading at various parts of the vehicle. Using these data, the computer system is capable to correct driver’s inattention in split second timing and make the driver’s reaction to be faster and safer.
