Abstract: A bake piston, which is arranged on a brake caliper of a disc brake of a vehicle, has a first and a second tubular piston body portion which are connected together at a first axial end of the brake piston via an annular end wall. The second piston body portion forms a receptacle in which a spindle nut of a spindle drive is accommodated so as to be axially displaceable and not rotatable relative to the brake piston, and receives a drive spindle. The first piston body portion has a radially inwardly directed floor region. The end wall is axially stepped towards the outside and has a radially outer portion and a radially inner portion which each have an end face pointing axially away from the brake piston, wherein the end face of the radially inner portion is axially offset relative to the end face of the radially outer portion in the direction towards the second axial end of the brake piston.

Abstract: The present disclosure relates to a brake caliper for a disk brake comprising a supporting structure having a bridge and at least one bridge finger. The at least one bridge finger has a brake lining side, an outer side and a bore, that extends into the outer side. The bore has a bore axis and a bore wall. A profiling is recessed into the bore wall. A faceplate having a peg, projects into the bore and has a peg circumferential surface. A sleeve, which has a sleeve body is arranged between the bore wall and the peg circumferential surface. The sleeve has a spring arm, which is bent outwardly in the radial direction away from the sleeve body. The profiling is designed in such a way that the outwardly bent spring arm can latch into the profiling at various points of the profiling in the axial direction of the bore axis.

Abstract: A brake piston is described which comprises a first tubular piston body portion and a second tubular piston body portion. The second piston body portion is connected to the first piston body portion and lies, in an axial view, radially completely inside the first piston body portion, thus forming an annular hollow space. Furthermore, a length of the second piston body portion along a piston longitudinal axis is at least 50% of a length of the first piston body portion. An inner circumferential surface of the second piston body portion comprises an anti-rotation contour which also forms an axial guide contour for a brake piston drive. Moreover, a method for manufacturing such a brake piston is explained. A brake caliper for a disk brake of a vehicle is also presented, which brake caliper comprises such a brake piston.

Abstract: An electric parking brake for an automotive vehicle comprises a brake caliper having first and second bores. A first piston is mounted in the first bore and a second piston is mounted in the second bore. A first actuator supports the first piston and a second actuator supports the second piston. The first and second actuators are controlled individually.

Abstract: A disc brake for a motor vehicle, wherein it is possible to displace the actuating piston in the housing both by hydraulic pressure activation of a hydraulic chamber formed in the housing and via a mechanical actuator, wherein the sealing ring is accommodated in an annular groove formed in the housing. Provision is made here for the annular groove to have a groove floor, which runs substantially parallel to the longitudinal axis of the piston, and two groove walls, which adjoin the groove floor, wherein—as seen in the direction of the longitudinal axis of the piston—a first groove wall is directed away from the hydraulic chamber and a second groove wall is directed towards the hydraulic chamber, wherein the first groove wall merges into the groove floor via a rounded or bevelled transition region at a varying distance from the longitudinal axis of the piston.

Abstract: The invention relates to a disk brake for a motor vehicle brake system having a frame-type housing, at least two brake pad arrangements, which are accommodated in the frame-type housing and between which a brake disk that is rotatable about an axis of rotation may be accommodated, and at least two guide bolts, which are mounted on the housing and on which at least one of the brake pad arrangements is guided with play in an axially displaceable manner. To avoid undesirable noises in this disk brake it is provided that on the brake pad arrangement guided on the guide bolts at least one spring element is mounted, which biases said brake pad arrangement relative to the guide bolts into a position corresponding to a tilting movement that results during braking of the brake disk from a braking torque acting on the brake pad arrangement.

Abstract: The invention relates to a disc brake having a brake carrier which is fastenable to a vehicle frame and provided with studs for guiding at least one brake lining axially with respect to a brake disc, wherein the brake lining includes U-shaped recesses for the studs into which the studs engage, and wherein during braking tensile forces and/or compressive forces are exerted upon inner surfaces of the recesses. The invention is characterized in that an inner surface of at least one of the U-shaped recesses, which surface bears against a respective stud during a brake actuation, is angled with respect to a central plane of the brake lining such that a force that arises between the said surface and the respective stud during braking presses the brake lining into a stable position with respect to the studs. The invention also relates to a brake lining for use in such a disc brake.
