Abstract: Flexible sheathing for the protection of piston-cylinder units for disc brakes are provided. Such flexible sheathing may be arranged in a retracted condition wherein the piston is completely accommodated within the cylinder and in an extended condition wherein the piston is completely extracted from a caliper body defining the cylinder. Pistons incorporating such flexible sheathings and calipers incorporating such pistons are also provided.

Abstract: The invention illustrates a caliper body (1) for a disc brake, suitable for being arranged astride of a disc (40) for a disc brake, said disc (40) defining a first braking surface (41) and a second braking surface (42) opposite the first braking surface (41); said caliper body (1) comprising a first half-caliper (2) and a second half-caliper (3), which are obtained by casting without machining and are suitable for being connected together at respective contact surfaces (4?, 4?) defining a joining plane (P) of the half-calipers; said first half-caliper (2) comprising a wheel-side elongated portion (5), extending in a tangential direction, which is suitable for facing an axially inner surface thereof towards the first braking surface (41), and at least one first projecting portion (11), projecting in an axial direction provided with a first contact surface (4?) suitable for connecting with the second half-caliper (3); said second half-caliper (3) comprising a vehicle-side elongated portion (6), extending in a t

Abstract: Flexible sheathing for the protection of piston-cylinder units for disc brakes are provided. Such flexible sheathing may be arranged in a retracted condition wherein the piston is completely accommodated within the cylinder and in an extended condition wherein the piston is completely extracted from a caliper body defining the cylinder, said piston having a piston outer surface suitable to co-operate with a cylinder inner surface of the caliper body which accommodates the piston, said outer surface having a predefined piston diameter and said cylinder inner surface having a predefined cylinder diameter, wherein said piston comprises a piston body and a head thereof suitable to press against a pad of the disc brake.

Abstract: Disk brake comprising an electrical wear sensor with an electrical connector (17?), a caliper (10) having an opening (8) and at least one pin (13) fixed to the caliper between two opposite sides of the opening and means for fixing the connector (17?) to the caliper (10). To avoid special processing operations of the caliper body and to provide an easy and rapid assembly of the connector, the fixing means comprise a carrier element (20) made of shaped sheet metal that has a first part (21, 26) to which the connector (17?) is fixed and a second part (23-25) that engages with the pin (13) and the edges of the opening (8) to provide a firm attachment of the carrier element (20) to the caliper (10).

Abstract: The protective device can be associated with a caliper body of a disc-brake caliper having a median plane of the caliper body which can be superimposed on a median plane of the disc arranged perpendicularly relative to an axis of rotation of the disc, the caliper body being arranged with a central portion astride the brake disc so that side walls thereof are arranged on opposite sides of the disc, the side walls of the central portion being connected to side portions so that the side portions are at least partially at the sides of the disc, each of the side portions comprising an opening of a hydraulic brake-fluid circuit defining an opening centre, the openings being in fluid communication with one another by means of a brake-fluid pipe arranged astride the central portion, the pipe supplying brake fluid between the side portions, the protective device comprising a shell for protecting the brake-fluid pipe and fixing means for fixing the shell to the caliper body, wherein the fixing means comprise at least o

Abstract: A disc brake pad is suitable for cooperating with a fixed-caliper disc brake comprising a caliper body provided with a seat suitable for housing the pad. The pad seat is defined by a side wall with which the abutment surface of the plate of the pad is brought into abutment during braking.
