Abstract:
1. A method for measuring the wear of a disk of composite ceramic material of a disk brake comprising the following operations: measuring the temperature (T) of the disk at a predetermined frequency (f), at every temperature measurement, calculating a wear increment (Δi) as a function of the measured temperature (T), summing the calculated wear increments (Δi), comparing the sum of the wear increments with the predetermined limiting wear index (i lim ) and signaling the eventual overstepping of the limiting wear index (i lim ), wherein the operation of calculating a wear increment (Δi) comprises the following steps: comparing the measured temperature (T) with a predetermined reference temperature (T r ) and calculating the wear increment (Δi) by using a first and a second predetermined function of the temperature when the comparison shows that the measured temperature (T), respectively, does and does not exceed the predetermined reference temperature (T r ).
