A wheel (28) and brake (34) monitoring system for a truck (20). The system is capable of detecting looseness of any wheel assembly (28) or excessive brake travel (36). Looseness of a wheel assembly (28) is detected by sensing lateral movement of the assembly or rotational movement between two wheels of that assembly. Looseness of a wheel assembly can alternatively be detected by sensing the change in position of the edge of a wheel rim (154), in relation to a fixed point (152) on the supporting axle assembly. Brake travel (78) is monitored by sensing excessive rotational travel of the slack adjuster associated with each axle. Excessive brake wear for an automobile can also be detected through the use of an embedded sensor wire (228) within the brake pads or shoes (230). |
