Abstract:
An electric-wear adjusting device of a motor vehicle disc brake is provided for adjusting friction surface wear on the brake linings and brake disc of the disc brake having. having a brake application device, preferably with a rotary brake lever. The adjusting device includes an electric motor, a gear mechanism, and an output element. The output element is connected rotationally fixed to a clamping sleeve. The clamping sleeve has inwardly projecting longitudinal ribs on an inner side configured to cooperate with axial grooves of a threaded plunger of a wear-adjuster spindle unit. Also provided is a corresponding disc brake having the electric wear-adjusting device, and a method for measuring and setting air play and measuring wear of a disc brake having the electric wear-adjusting device.

Claim (Index 20):
A method for measuring friction-induced wear of brake pads and of a brake disk of a disk brake as claimed in  claim 13 , comprising the acts of:\n defining an initial position (x initial ) of the brake pad; storing the initial position (x initial ) in the control unit; measuring a present air gap; calculating the friction-induced wear on the basis of the initial air gap, an overall wear adjustment rotational angle \u03b1 overall , a gearing transmission ratio i, the present air gap LS and spindle pitch p in accordance with the following calculation rule:\n x wear =x initial \u2212\u03b1 overall *i*p+LS  \n determining whether a brake pad change is necessary by comparing the calculated friction-induced wear with a predefined value; and if a pad change is determined to be necessary, generating and at least one of displaying and communicating an item of information indicating a need to change the brake pads.
