A method and apparatus for analysis of brakes in automotive vehicles, and related aspects of engine performance and like applications, senses heat energy which is generated internally of an article to be analysed. Spot-type infra-red thermometers are employed to sense localised temperature elevation produced by brake application from a remote location using visual positioning guides to enable the spot zones sensed to be accurately located on, for example, wheel nuts/studs, which provide a thermal transfer route from the brake drums or discs. Analysis of the thermal data from the sensors includes a peak detect-and-hold function to avoid the need for maintenance of accurate alignment of the sensors. Comparison of the thermal data enables detection of braking imbalance.

[ We claim:] [1.] A method for analysis of the performance of a machine comprising the steps of:remotely sensing temperature at a defined spot or zone location on a first portion of the machine after the machine has effected a machine operation;then repeating the remote sensing step in relation to a second portion of the machine spaced from the first portion; andcomparing data from the temperature sensing steps to determine the degree of thermal imbalance between the first and second portions of the machine as a basis for operational diagnosis of the machine.
