Monitoring apparatus for wheel units of an automobile
In a monitoring apparatus, a conductive coupling member is embedded in a brake pad of a brake system and is spaced apart from a first brake member by a thickness of the brake pad when wearing of the brake pad has yet to reach a predetermined worn-out state. A wear detecting circuit is coupled to the coupling member for detecting wear condition of the brake pad, and is capable of outputting a wear signal when the brake system is activated and the brake pad ceases to space apart the coupling member from the first brake member. A pressure detecting unit generates a pressure signal in accordance with pressure condition in a pneumatic tire. A processing unit receives the wear signal and the pressure signal, and enables an indicating unit to indicate the pressure condition in the pneumatic tire and the wear condition of the brake pad.
