Abstract
A brake actuator for an electrical parking brake comprises an electric motor and a planetary gear set. The axes on which the planet wheels are carried on the planet carrier are joined substance-to-substance to the planet carrier, i.e. formed in one piece with it or for instance mounted on its surface by means of atomic or molecular forces. Recesses on the axes can receive a lubricant. Spacers between the planet carrier and planet wheels can reduce the contact surface in the axial direction.
