A reliable method of predicting brake block wear could lead to substantial economies of time and money. This paper describes how such a procedure has been developed and gives the results of a first attempt to establish its reliability by comparing the predicted wear with that which actually occurs in an existing service. A new approach to laboratory-scale wear testing has enabled the wear per unit energy dissipated of a given composition material to be determined for any relevant combination of the three basic parameters - tyre surface temperature, rubbing speed and applied force. The values of energy dissipation, rubbing speed and brake force at any instant during a given service are calculated from a knowledge of the relevant vehicle parameters and from direct observation or calculation of the braking duties undertaken. The surface temperatures are calculated from this data using one-dimensional heat flow equations which are improvements on those developed previously. A computer program has been developed which calculates these temperatures and uses the laboratory wear data to work out the predicted wear for the service being studied. The wear results have also led to an improved understanding of the wear processes involved.
