Brake assembly with active piston retraction

A brake assembly comprising:

• a brake piston configured to be movable for a brake apply or release, the brake piston having an inner wall forming a piston cavity;
• a linearly movable structure positioned within the piston cavity of the brake piston, the linearly movable structure configured to be linearly movable within the piston cavity in response to rotation of a rotatable structure operably coupled to the linearly movable structure;
• and
• a magnet disposed between the brake piston and the linearly movable structure so that the brake piston is movable toward the linearly movable structure in response to linear movement of the linearly movable structure by magnetic field generated by the magnet,
• wherein:
• the magnet is mounted to the inner wall of the brake piston, and
• the linearly movable structure has magnetically-attractive material attractable by the magnet so that an attractive magnetic force is generated between the linearly movable structure and the magnet mounted to the brake piston.
