Disc brake, especially for vehicles

A disc brake, particularly for vehicles, having a stationary housing,

• at least one friction or brake lining which, when the brake is actuated, is displaced with respect to the housing,
• a lever device with a shaft including an eccentric rotatable about a first axis and with an actuating lever fastened to the shaft and extending essentially perpendicularly to the first axis such that, as a result of the rotation of the shaft about the first axis, the brake can be actuated,
• an eccentric follower displaceable within the housing along a second axis which extends essentially perpendicularly to the first axis, the follower resting with a first end on the eccentric and with a second end acting with respect to the brake lining;
• and
• adjusting means for increasing the distance separating the first axis from the second end of the follower as a function of the wear of the brake lining, wherein;
• the eccentric has two bearing sections arranged on either side of the rotating lever;
• the eccentric follower has, on its first end, a nut with a central threaded bore as well as two essentially semi-cylindrical lateral bearing shells receiving the corresponding bearing sections of the eccentric;
• the eccentric follower has a screw whose first end engages the nut, while a second end of the screw forms the second end of the eccentric follower;
• and
• the adjusting means generates a relative rotation of the screw and of the nut whereby the second end of the eccentric follower can be extended.
