1. 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, wherein a groove is formed on the inner wall of the brake piston;
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 resilient material, wherein at least a part of the resilient material is located within the groove formed on the inner wall of the brake piston and an other part of the resilient material is disposed on an outer surface of the linearly movable structure positioned within the piston cavity of the brake piston so that the resilient material is engageable with side walls of the groove formed on the inner wall of the brake piston to move the brake piston by a restoring force of the resilient material in response to linear movement of the linearly movable structure,
wherein the resilient material does not contact a circumferential surface formed between the side walls of the groove of the brake piston so that the resilient material is movable between the side walls of the groove of the brake piston without contacting the side walls of the groove of the brake piston.
