It is very important and unquestionable that we need to have a clear technical requirement for Air Brake Systems and its components, since it is one of most important regarding safety. Looking to heavy commercial vehicles and possible air brake system failures, everything becomes clearly to pay total attention for these normative and regulatory requirements.
Historically, the development of Brakes technology has started on EUA and Europe and consequently two strong and distinct requirements were structured: FMVSS 121 and ECE-R13.
From decades people are trying to harmonize these requirements and for passenger cars, the evolution was faster. However, for commercial vehicles there are more peculiarities considering regional applications and some of them cultural and implementation time.
As globally market is growing so fast as well new markets around the world, become fundamental the clearly understanding of these similarities, variants, peculiarities and correlated requirements.
This article shows a bibliographic and the North America and Europe requirement history also discussing the influence on the Brazilian commercial vehicles considering technical view as well strategies for last level of global technology introduction.
Other historically fundamental bases for the development and validation of the brake system, such as ISO and SAE standards will also be addressed, considering its interface with auditing standards published by ABNT. It will show Brazilian scenario for searching improvements and development for new requirements and standards updating to reinforce Brazilian regulation (CONTRAN) bases focusing at vehicles safety.
