The brake mechanism for a disc brake is received in a caliper by means of pivots. The brake mechanism comprises a lever, a cross bar, a thrust yoke and an adjuster mechanism. The thrust yoke is provided with braces going diagonally from the center of the thrust yoke down to the backside of the thrust plate. The structure of the thrust yoke ensures that the force is applied in distinct, separated areas of the brake pads. The brake mechanism is held together as one unit which facilitates handling and assembly.

1. A disc brake mechanism for transmitting a brake force from a brake cylinder to brake pads via a lever, a cross bar and a thrust yoke, which is connected to a brake pad carrier, characterized in that the thrust yoke has a central aperture receiving a screw, in which a guide of the cross bar is received, and has braces that go diagonally from the area of the aperture downward and outward to the backside of a plate of the thrust yoke for distribution of the brake force on the brake pads. 2. The disc brake mechanism of claim 1, characterized in that the thrust yoke is provided with one or more raised portions on the surface facing a brake pad support and that the braces go inclined from the area of the raised portions towards a guide of the cross bar. 3. The disc brake mechanism of claim 2, characterized in that the thrust yoke has two raised portions placed on alternate sides of the centre of the surface of the thrust yoke facing the brake pad. 4. The disc brake mechanism of claim 1, characterized in that the lever has an outer surface of a non-circular shape, which surface abuts two rollers contained between the lever and the cross bar and that the rollers are received in one or two recesses of the cross bar. 5. The disc brake mechanism of claim 1, characterized in that an adjuster mechanism is attached to a splined shaft, which shaft is received in the centre of a guide of the cross bar. 6. The disc brake mechanism of claim 5, characterized in that the adjuster mechanism is attached to an adjuster shaft by means of a bushing; that a guide ring is mounted on the bushing in order to guide the lever in horizontal direction; and that the lever has guiding faces in rolling contact with the guide ring. 7. The disc brake mechanism of claim 6, characterized in that the distance between the guiding faces of the lever is less than the outer diameter of the adjuster mechanism. 8. The disc brake mechanism of claim 1, characterized in that the thrust yoke is furnished with a protective header, a bellows and a bellows clamp and that the bellows surrounds the thrust yoke. 9. The disc brake mechanism of claim 1, characterized in that the cross bar has two apertures at diagonally opposite corners for receiving spring supports. 10. The disc brake mechanism of claim 9, characterized in that the inner diameter of the apertures of the cross bar is greater than the outer diameter of the spring supports; that return springs are received on the spring supports; and that the springs are biased in a radial direction by means of a surface of the spring supports. 11. A disc brake mechanism for transmitting a brake force from a brake cylinder to brake pads via a lever, a cross bar and a thrust yoke, which is connected to a brake pad carrier, characterized in that the thrust yoke has a central aperture and has braces that go diagonally from the area of the aperture downward and outward to the backside of a plate of the thrust yoke for distribution of the brake force on the brake pads and wherein the lever has an outer surface of a non-circular shape, which surface abuts two rollers contained between the lever and the cross bar and that the rollers are received in one or two recesses of the cross bar. 12. A disc brake mechanism for transmitting a brake force from a brake cylinder to brake pads via a lever, a cross bar and a thrust yoke, which is connected to a brake pad carrier, characterized in that the thrust yoke has braces for distribution of the brake force on the brake pads and an adjuster mechanism is attached to a splined shaft, which shaft is received in the centre of a guide of the cross bar and the adjuster mechanism is attached to an adjuster shaft by means of a bushing; that a guide ring is mounted on the bushing in order to guide the lever in horizontal direction; and that the lever has guiding faces in rolling contact with the guide ring. 13. The disc brake mechanism of claim 12, characterized in that the distance between the guiding faces of the lever is less than the outer diameter of the adjuster mechanism. 14. A disc brake mechanism for transmitting a brake force from a brake cylinder to brake pads via a lever, a cross bar and a thrust yoke, which is connected to a brake pad carrier, characterized in that the thrust yoke has a central aperture and has braces that go diagonally from the area of the aperture downward and outward to the backside of a plate of the thrust yoke for distribution of the brake force on the brake pads and that the thrust yoke is furnished with a protective header, a bellows and a bellows clamp and that the bellows surrounds the thrust yoke.
