Abstract:
A disc brake arrangement for motor vehicles, comprising at least two brake pad units supported by a brake yoke, one side of each said at least two brake pad units comprising a frictional surface, which is arranged to face a rotatable brake disc and the other side of said at least two brake pad units which is arranged to face an actuator, whereby, when in a position for braking the vehicle, each brake pad unit is arranged to be brought into an active position by means of at least two actuators acting against said other side of each said at least two brake pad units and to be allowed to be returned to a retracted, passive position, whereby each actuator comprises an end portion which is intended to transfer to each said at least two brake pad units movement of said at least two actuators towards and from said other side of said at least two brake pad units, which on said other side of said at least two brake pad units comprises a first coupling means arranged for each actuator, whereby each actuator end portion comprises second coupling means arranged for positioning of said at least two brake pad units, said adjustment device exhibits a screw rotatable in each actuator, said screw in its end facing the brake pad unit, a pivot bearing, supporting said end portion of the acutators, whereby a protective bellows may be mounted between said end portion and the brake yoke, both said first and second coupling means comprises interacting guiding surfaces, which are arranged to prevent rotation of each end portion of the actuators about an axis, transverse to said other side of said at least two brake pad units.
