Abstract: The invention relates to a disc brake with a housing, at least one brake pad, a lever device with an eccentric consisting essentially of a shaft fitted with an actuating or rotating lever, and with a pressure member or eccentric follower. The eccentric has two bearing sections on either side of the rotating lever; the eccentric follower has a bolt engaging in the central threaded hole of a nut. Two lateral bearings on the nut receive the bearing sections of the eccentric. There are mechanisms for taking up wear which extend the eccentric follower according to the wear of the brake pad by screwing the bolt out of the nut.
