A dirt scraper for a disc brake of a vehicle includes at least one scraper blade adapted to abut a braking surface of the disc for scraping off dirt when the disc rotates, and a heat sensitive structure for moving the at least one blade from a first position where it abuts the surface of the disc to a second position where it does not abut the surface of the disc, when the temperature of the heat sensitive structure increases, and vice versa.
