Floating calliper for disc brake comprising a calliper body and a bracket, wherein the calliper body is suitable for being positioned astride the disc brake, extending from an inner side to an outer side of the calliper, the bracket comprises means of attachment of the calliper for disc brake to a relative support, the calliper body sliding in relation to the bracket in an axial direction, the calliper comprising means of coupling between the calliper body and the bracket, suitable to permit the relative sliding between these parallel to the axial direction. The bracket extends only on the inner side of the calliper and delimits a first seat housing at least a first pad to exert the braking action on an inner side of the disc brake. The calliper body delimits a second seat, axially opposite the first seat, so as to house at least a second pad exerting a braking action on an outer side of the disc brake facing the outer side of the calliper. Advantageously, the coupling means comprise a guide pin and an attachment pin, the guide pin enabling and guiding a relative sliding, in the axial direction, of the calliper body in relation to the bracket and the attachment pin angularly blocking the calliper body on the bracket, preventing its rotation in relation to the guide pin, so that the calliper body is axially guided solely by the guide pin.

Floating calliper for disc brake

A device for retracting a piston for a brake caliper is disclosed. The device is suitable for actuating at least one pad for brake calipers of the type comprising a body arranged astride of a brake disc having a rotation axis and two opposite friction surfaces perpendicular to the rotation axis. The piston is suitable for axially translating, thus bringing each pad in contact with force against a respective friction surface of the disc, generating a braking friction torque that is opposite to the rotation direction of the disc. The piston is slidably actuated within a respective seat formed in the caliper body, biased by the pressure of a brake fluid supplied by a supplying plant, in a manner that is controlled by a user to carry out a braking action.

Device for retracting a piston

Caliper bodies for disc brakes are provided. Such caliper bodies are suitable for being arranged astride a disc for a disc brake. Calipers which include such caliper bodies are also provided.

Caliper bodies for disc brakes

Brake caliper bodies and brake calipers for disc brakes are provided.

Caliper body of a disc brake

A brake caliper comprising a piston seat () wherein a piston () slides with its side surface () in contact with a radial surface () of an elastic member (). The member further comprising two axial surfaces () adapted to be affected by a pressurized fluid and being arranged at the piston coming out side facing the pads respectively. The latter surface facing with a portion () thereof, a first chamber () arranged in the proximity of the piston side surfaces, with another portion () thereof, an abutment surface () adapted to support said elastic member when it is urged by the pressurized fluid, said abutment surface being radially retracted so as to be farther from the piston side surface than said first chamber and with a further portion () thereof, at least one second chamber () arranged radially farther from said piston side surface than said abutment surface.
