Abstract: Disc brake having a caliper displacable on a stationary support to press a pair of brake shoes on each side of a brake disc, a brake operating device having a piston rod acting upon a rotating lever, the rotating lever rotates about a first axis perpendicular to the axis of the brake disc, the rotating lever interacting with a pressure piece by an eccentric bearing having a shaft which can be swivelled about a second axis on the rotating lever which second axis is offset with respect to the first axis of rotation of the rotating lever. The shaft of the eccentric bearing interacts with the rotating lever by coaxial cylindrical shaft situated on both sides of the pressure piece.

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.
