## Abstract

The invention relates to a self-reinforcing electromechanical disk brake. The invention proposes to produce a lining carrier plate of the disk brake from a fiber composite material. A bending-resistant lining carrier plate can be produced cost-effectively in this way. In addition to fiber-reinforced plastic, steel-reinforced concrete can also be considered as a composite material for the lining carrier plate.

## Claims

### Claim at position 1

1-5. (canceled)

### Claim 6

A self-boosting electromechanical disk brake, comprising:
an electromechanical actuating device;
a friction brake lining disposed on a lining carrier plate;
a brake disk which is pressed against by the friction brake lining upon actuation of the electromechanical actuating device; and
a self-booster device interposed between the electromechanical actuating device and the friction brake lining, the self-booster device converting a frictional force, exerted by rotation of the brake disk against the friction brake lining pressed against the brake disk, into a contact pressure of the self-booster device, which presses the friction brake lining against the brake disk in addition to a contact pressure exerted by the electromechanical actuating device, wherein the lining carrier plate comprises a composite material.

### Claim 7 (depends on 6)

The self-boosting electromechanical disk brake as defined by claim 6, wherein the lining carrier plate comprises a laminated composite material or a fiber composite material.

### Claim 8 (depends on 6)

The self-boosting electromechanical disk brake as defined by claim 6, wherein the lining carrier plate has a rack disposed thereon which is driven by the electromechanical actuating device, and wherein the rack comprises a wear-resistant material.

### Claim 9 (depends on 8)

The self-boosting electromechanical disk brake as defined by claim 8, wherein the rack is joined to a reinforcement of the composite material.

### Claim 10 (depends on 6)

The self-boosting electromechanical disk brake as defined by claim 6, wherein the lining carrier plate has a fastening element, which is joined to a reinforcement of the composite material.
