Abstract: In a method for producing a brake carrier for a disc brake of a vehicle braking system, wherein the brake carrier has at least one guiding shaft for guiding a brake lining in a guiding direction in relation to a receiving region for a brake disc, first a brake carrier blank is produced in a casting step and then the brake carrier blank is reworked. In the casting step, the brake carrier blank forms two converging tapers, facing the receiving region, in the region in which the guiding shaft is formed and, during the reworking, material is removed in the region of the tapers to produce the at least one guiding shaft, with the effect that the receiving region for the brake disc has a predetermined clear width transversely in relation to the guiding direction.

Abstract: A brake disc has an outer friction path on one side and an inner friction path on the other side. Between the friction paths free spaces are provided, which on the outer friction path side have a different configuration than on the inner friction path side.

Abstract: A brake actuator for an electrical parking brake comprises an electric motor and a planetary gear set. The axes on which the planet wheels are carried on the planet carrier are joined substance-to-substance to the planet carrier, i.e. formed in one piece with it or for instance mounted on its surface by means of atomic or molecular forces. Recesses on the axes can receive a lubricant. Spacers between the planet carrier and planet wheels can reduce the contact surface in the axial direction.

Abstract: Methods are described, with which by expansion of metal foam it is possible in particular to manufacture pistons for brakes. This enables pistons of a very low wall thickness and high strength.

Abstract: An axle journal (20), especially for the front axle of a front wheel drive motor vehicle comprises a main body (30) made of shaped sheet metal parts (32, 34) which enclose a circumferentially extending cavity (36). The cavity (36) houses portions (43) and (46) of mounting components (brake carrier member 42 and a combination 45 steering tie rod mount and transverse link seat) which portions stiffen the axle journal (20). The section of the cavity not taken up by the stiffening portions of the mounting components may be foam-filled. This composite-structure axle journal can be manufactured at low cost due to the reduced mechanical finishing required and can sustain heavy loads, whereby it meets present day requirements of lightweight construction.

Abstract: An electronically controllable braking system for ground vehicles, comprising a cylinder/piston arrangement (6) which is able to introduce friction forces (F.sub.akt) into a friction element (8) which is coupled with a vehicle wheel by subjecting a hydraulic chamber (4) of the cylinder/piston arrangement (6) with hydraulic fluid, is developed further in that an electrically actuatable displacement element (12) projects into the hydraulic chamber (4) of the cylinder/piston arrangement (6) which is actuatable as a function of control signals from an electronic controller (22) for increasing or decreasing the pressure acting on the hydraulic fluid in the hydraulic chamber (4) in order to increase or decrease, respectively, the friction forces (F.sub.akt) which, during a braking operation, are introduced into the friction element (8).
