Brake envelope (contour) test

The purpose of the test is the detection of the deformation induced inside the wheel under load, in order to ensure the absence of interference with the brakes contour.
The strain measurements are detected by two sensors (magnetic inductors). The test is carried out both in static and dynamic conditions (rotating wheel).
