A heavy-vehicle brake assembly is provided. The brake assembly includes: a braking element including friction material having an engaging face, the braking element configured to be actuated in a braking operation so that the engaging face of the friction material engages a braking surface to slow a heavy-vehicle; and a wear sensor assembly. The wear sensor assembly comprises: an ultrasonic sensor for emitting and detecting high-frequency sound waves; and a sacrificial member having an engaging face arranged to face the braking surface, wherein the sacrificial member is arranged such that sound waves emitted by the ultrasonic sensor pass through the sacrificial member; wherein the engaging face of the sacrificial member is flush with the engaging face of the friction material of the braking element and the sacrificial member is configured to actuate together with the braking element during the braking operation so that the engaging face of the sacrificial member also engages the braking surface.
