A method of measuring thickness of a braking component in a heavy vehicle brake assembly of the kind comprising a braking element including friction material having an engaging face, the braking element being configured to be actuated in a braking operation so that the engaging face of the friction material engages a braking surface of the braking component to slow a heavy vehicle. The method comprises: determining when an ultrasonic device comprising an ultrasonic emitter is in an engaged state in contact with the braking surface; when the ultrasonic device is in the engaged state, emitting high-frequency sound waves through the braking component with the ultrasonic emitter and detecting the high-frequency sound waves with an ultrasonic sensor; and calculating a thickness of the braking component based on a time delay between emitting and detecting the high-frequency sound waves.
