1. Method for the reconditioning of a friction pair (3) comprising a lining and a rotor in a service brake (2) of the drum or disc brake type forming part of a brake system of a vehicle, which in addition to the service brake (2) comprises one or more auxiliary brakes (10) and a control system (11) for distribution of the requested brake power between the service brake and auxiliary brake or auxiliary brakes, the method comprising the following stages:
determination (30, 41) of a parameter value (I) for a reconditionable surface characteristic;
reconditioning (33, 43, 44) the friction pair through the supply of a defined braking energy (E), as a function of said parameter value (I) determined for said friction pair (3) and wherein said parameter value is estimated from the set of parameters through the formation of a function In+1=In+ΣαaACA, where In+1 is the current value of the parameter value and αA is a weighted function for a parameter CA.
