Abstract

A brake diagnosis apparatus for a self-propelled vehicle can secure the safety of the brake and the productivity of mining and quarrying and can detect widely applicable data including the history. In order to achieve this, there is provided oil temperature detecting means (23) for detecting a cooling oil temperature d immediately after the oil cools a brake; holding time calculating means, for receiving the cooling oil temperature d from the oil temperature detecting means and for calculating a holding time t thereof; and a first adding means (31a), having stored therein a first matrix A, which is sectioned in vertical and horizontal directions at every predetermined cooling oil temperature area and at every predetermined holding time area, for receiving the cooling oil temperature d from any one of the oil temperature detecting means and the holding time calculating means, for receiving the holding time t from the holding time calculating means, for adding a frequency of occurrence value An to the area of the first matrix A which includes the cooling oil temperature d and the holding time t, and for freely outputting the added value to an outer portion.
