Disk brake and method for manufacturing the same

1. A disc brake comprising a brake caliper, which overlaps at least one brake disc, and a brake actuation mechanism having:

an amplification mechanism comprising a brake lever being rotatable around a pivot bearing for introducing a clamping force from an actuator, the brake lever having an arm extending between an actuator connection means and a transmission means,

a thrust element in connection with said transmission means for transmitting the amplified clamping force onto the brake disc,

wherein the brake lever comprises a recess between the actuator connection means and the transmission means, which recess is traversed by the axis of said pivot bearing,

a rod extending between the amplification mechanism and the thrust element,

a mounting brace having means for receiving the rod, and

an inner recess on the brake caliper adapted to receive one end of the mounting brace and an opening opposite to the inner recess.

2. The disc brake of claim 1 , in which the brake lever is configured and arranged in relation to the thrust element so that the clamping force from the actuator is substantially directed perpendicularly to the axis of the brake disc upon brake actuation.

3. The disc brake of claim 1 , in which the amplification mechanism and the thrust element are mounted in functional cooperation in the brake caliper by means of the rod that is supported in the housing of the brake caliper so as to be non-displaceable in an axial direction.

4. The disc brake of claim 3 , in which the rod extends into said recess.

5. The disc brake of claim 4 , wherein said mounting brace traverses said recess.

6. The disc brake of claim 5 , in which the means for receiving said rod is configured to allow a force-fit and/or form-fit with the rod.

7. The disc brake of claim 5 , in which the mounting brace is releasably fixed in the brake caliper.

8. The disc brake of claim 7 , wherein the opening is adapted to allow insertion of the mounting brace into the brake caliper.

9. The disc brake of claim 4 , in which the brake lever is configured to be mounted at different angular positions around the axis of the rod.

10. A method for manufacturing a disc brake, which comprises a brake caliper, which overlaps at least one brake disc, and a brake actuation mechanism having:

an amplification mechanism comprising a brake lever being rotatable around a pivot bearing for introducing a clamping force from an actuator, the brake lever having an arm extending between an actuator connection means and a transmission means, in which the brake lever further comprises a recess between the actuator connection means and the transmission means, for transmitting the amplified clamping force onto the brake disc,

wherein the amplification mechanism with the brake lever and the pivot bearing are mounted in functional cooperation as a self-supporting first unit by means of a rod; comprising the steps of:

inserting the first unit into the brake caliper through an opening from the brake disc-side;

inserting a mounting brace through a lateral opening in the brake caliper such that the mounting brace traverses the recess of the brake lever;

connecting the end of the rod, the end facing the rear of the brake caliper, with the mounting brace.

11. The method of claim 10 , in which the mounting brace comprises a threaded passage and the end of the rod comprises a thread, further comprising the steps of:

applying a rotatable mounting tool at the side of the rod being axially opposite to its threaded end; and

rotating the rod so as to screw its threaded end into the threaded passage of the mounting brace.

12. The method of claim 10 , further comprising the steps of:

attaching a second unit comprising the thrust element to the brake disc-side end of the first unit, the thrust element comprising an inner thread and the brake disc-side end of the first unit comprising an outer thread; and

activating a reset device being in connection with the first unit thereby screwing the second unit onto the first unit.

13. A method for manufacturing a disc brake, which comprises a brake caliper, which overlaps at least one brake disc, and a brake actuation mechanism having:

an amplification mechanism comprising a brake lever being rotatable around a pivot bearing for introducing a clamping force from an actuator, the brake lever having an arm extending between an actuator connection means and a transmission means, in which the brake lever further comprises a recess between the actuator connection means and the transmission means, which recess is traversed by the axis of said pivot bearing;

a thrust element in connection with said transmission means for transmitting the amplified clamping force onto the brake disc,

wherein the amplification mechanism with the brake lever and the pivot bearing and the thrust element are mounted in functional cooperation as a self-supporting unit by means of a rod;

comprising the steps of

inserting the unit into the brake caliper through an opening from the brake disc-side;

inserting a mounting brace through a lateral opening in the brake caliper such that the mounting brace traverses the recess of the brake lever; and

connecting the end of the rod, the end facing the rear of the brake caliper, with the mounting brace thereby enabling a form-fit and/or a force-fit.

14. The method of claim 13 , the rod comprising engagement means and the mounting brace comprising engagement means being complementary therewith, further comprising the step of:

laterally shifting the mounting brace over the end of the rod thereby bringing the engagement means of both the mounting brace and the rod into engagement.

15. The method of claim 14 , the brake actuation mechanism further comprising an adjustment mechanism and a reset device cooperating with said adjustment mechanism, the reset device comprising a return spring element, wherein the adjustment mechanism, the reset device with the spring element, the amplification mechanism with the brake lever and the pivot bearing and the thrust element are mounted in functional cooperation as a self-supporting unit by means of said rod, further comprising the step of:

displacing the rod in axial direction upon laterally shifting said mounting brace over the end of the rod, and thereby

applying a defined pretension to said return spring element.
