Abstract

The present invention relates to a method for diagnosing the wear of a disc brake arrangement of a vehicle. The disc brake arrangement comprises a disc, a first and second brake pad arranged on opposite sides of the disc, a brake pad carrier for supporting said brake pads, a brake caliper, and an actuating arrangement for pressing the first brake pad applied against said disc and causing a movement of said brake caliper thereby pressing the second brake pad against said disc. The method comprises the step of, by means of a first sensor unit, determining (S1) the stroke of the actuating arrangement for applying said first brake pad against said disc. The method further comprises the steps of: by means of a second sensor unit, determining (S2) the stroke of said brake caliper for applying said second brake pad against said disc; and determining (S3) the individual wear of said brake pads based upon said determined strokes.The present invention also relates to a system for diagnosing the wear of a disc brake arrangement. The present invention also relates to a vehicle. The present invention also relates to a computer program and a computer program product.(Fig. 4)
