Claim:
1. A method for providing a clamping force generated by an automatic parking brake, comprising: activating a brake motor to move a brake piston toward a brake disk to generate the clamping force a first time; and after a first predetermined time period has elapsed after the first application process has been completed, activating the brake motor to move the brake piston toward the brake disk a second time; detecting an amount of rotation or electrical resistance of the brake motor over a second predetermined time period, the amount of rotation or electrical resistance detected being indicative of losses in clamping force; after the second predetermined time period has elapsed, carrying out a secondary application process as a function of the detected amount of rotation or electrical resistance of the brake motor over the second predetermined time period, wherein the secondary application process is carried out independently of information on a temperature of the brake disk temperature.
