abstract

  • Vehicle systems such as the steering, brakes and suspension greatly influence vehicle safety. Therefore, these systems must be inspected to guarantee that they are functioning
    correctly and to certify that the vehicle is functioning at a
    satisfactory
    safety level. In disc brakes, warping is one of the
    principal reasons for vibrations and noise, and it contributes to
    diminished
    brake efficiency. Currently, the International Motor Vehicle
    Inspection Committee (CITA) demands disc brake warping inspections
    occur during periodic motor vehicle inspections (PMVIs);
    however, the procedure to carry out this inspection is not well defined.
    In this investigation, the warping phenomenon has been
    analyzed, and a new inspection procedure is proposed.
