The high level of reliability of virtual analysis for suspension system development should not be thinking only for comfort and performance purpose, considering the `growing number of failures due to the touch between components in dynamic condition.
The study establishes a simple and optimized methodology, able to predict more accurately the flexible brake hose path subject to the steering motion and associates with the independent suspension course, aiming the best route in order to achieve a low cost and robust design.
In turn, the flexible brake hose non-linear model invalidates the multibody study to get the best route. However, with the aid of motion making use of NX9  CAD  software was prepared dynamic movement that subjects front independent suspension system that establishes a Cartesian routine that maps 977 points, much higher than 9 points from previous studies, comprising a more accurate path performed by the hose.
This data served as input to the IPS  software for the construction of flexible model to be simulated, were assigned mechanical and geometrical properties for each component.
Finally, it was set to IPS software the dynamic suspension system routine, thus yielding the flexible brake hose behavior under certain circumstances, verifying the effectiveness of the component to the package requirements, avoiding undesired dynamic interference and early degradation of the flexible element.
