A brake of disc brake type with at least one brake block, which is non-rotatably supported and can be pressed against a rotating brake disc. In this connection a brake disc is a denomination comprising any rotating element with a substantially axially directed friction surface, against which a brake block is actuating. The brake surface can also exhibit a conical shape. It is an object of the invention to provide a safe braking means of simple construction preferably with a servo effect and fit for universal use at the same time as it is well suited for application in connection with bicycles and similar vehicles. According to the invention the brake block (5) is supported by a support (6) extending along the friction surface of the brake disc (2), said support being supported in a bearing (8), which for one thing is movable away from and towards the friction surface of the brake disc and for another thing is displaceable relative to the support along said friction surface against bias of a yielding force, the bearing being adapted to the effect that said movement in direction towards the friction surface of the brake disc is obtained by force, when the brake block with the support belonging to the same is displaced along the friction surface against bias of said yielding force, which tends to return the support with its brake block to its starting position. |
