Abstract
A method and device are provided for indicating wear of at least one brake pad in a disc brake having an electric motor actuator. The method adds up wear adjustment travel paths of the electric motor actuator and/or of an adjustment motor, and indicates the sum of the wear adjustment paths so obtained as the wear of the brake pad or as a residual brake pad service life.

A method for indicating the wear or residual brake pad thickness of at least one brake pad in a disc brake having an electric motor actuator, the method comprising the acts of:
- adding wear adjustment travels of at least one of the electric motor actuator and an adjustment motor;
- and
- indicating the wear or residual brake pad thickness of the at least one brake pad based on a sum of the wear adjustment travels.
A device for indicating wear of at least one brake pad in a disc brake having an electric motor actuator, the device comprising:
- a comparator module for comparing positions of the electric motor actuator and/or an adjustment motor;
- an adding module for adding wear adjustment travels;
- a display module for displaying wear of the brake pad;
- and
- a control module for controlling the comparator module, the adding module, and the display module, the control module transmitting control signals for reference adjustments of the electric motor actuator and/or the adjustment motor to the brake control unit.
A disc brake having at least one brake pad, the disc brake comprising:
- an electric motor actuator;
- a device for indicating wear of the brake pad;
- wherein the device comprises:
- a comparator module for comparing positions of the electric motor actuator and/or of an adjustment motor;
- an adding module for adding wear adjustment travels of the electric motor actuator and/or an adjustment motor;
- a display module for displaying wear of the brake pad;
- and
- a control module for controlling the comparator module, the adding module, and the display module and for transmitting control signals for reference adjustments of the electric motor actuator and/or the adjustment motor to the brake control unit.
