Abstract
A pneumatically actuated disc brake includes a caliper that straddles a brake disc, at least one brake application device, and at least one adjusting device, which is provided with an electromotive drive unit. The disc brake and a control method therefore are characterized by the fact that the at least one electromotively driven adjusting device is also used as a parking brake and/or emergency brake.

1-19. (canceled)
A pneumatic disc brake for use with a brake disc, comprising:
- a caliper which, in use, straddles the brake disc;
- at least one brake application device for applying the brake, the brake application device being arranged in the caliper on one side of the brake disc when in use;
- at least one wear adjusting device for compensating brake pad wear, the at least one wear adjusting device having at least one electromotive drive and being operatively configured to function as a parking and/or emergency brake;
- wherein the electromotive drive includes an electric motor and is operatively dimensioned to drive the wear adjusting device to function as the parking and/or emergency brake.
A method of controlling a pneumatically actuated disc brake, the method comprising the acts of:
- signaling the use of a parking and/or emergency brake function for the disc brake;
- and
- using an electromotive wear adjusting device of the disc brake to implement the parking and/or emergency brake function.
A parking brake for a vehicle equipped with a pneumatic disc service brake, comprising:
- at least one electromotively driven brake pad wear adjusting device of the pneumatic disc service brake;
- an electromotive drive including an electric motor for the brake pad wear adjusting device;
- and
- wherein the electromotive drive is operatively dimensioned to control the service brake as the parking brake.
