Brake system with torque limiter assembly

A brake system comprising:

• an electromechanical actuation system comprising at least a first portion and a second portion, each of the first and second portions comprising:
• a torque limiter assembly setting a torque limit and comprising:
• a planetary gear meshed with a sun gear,
• a ring gear meshed with the planetary gear and comprising a first race extending circumferentially therearound,
• a pre-loaded member comprising a second race extending circumferentially therearound, and
• balls engaged between the first race and the second race;
• wherein the first race and/or the second race comprises a series of peaks and valleys, and slopes extending therebetween;
• wherein below the torque limit, the balls are engaged within the valleys causing the ring gear to remain rotationally captive and the planetary gear to orbit around the sun gear;
• and
• wherein at and above the torque limit, the balls slip over the peaks, causing the ring gear to rotate and the planetary gear to remain orbitally captive.
