Electrically actuated disc brake assembly

A vehicle having a disc brake assembly, comprising:

• a brake pedal;
• a controller operatively connected to said brake pedal;
• a hub rotatable about an axis;
• at least a pair of brake discs supported on said hub for rotation therewith and for axial sliding movement relative to said hub along said axis and having opposite sides presenting braking surfaces;
• a non-rotatable support structure;
• a plurality of friction elements supported by said non-rotatable support structure for relative axial movement into and out of frictional braking engagement with said braking surfaces;
• a piston moveable from an unactuated position to an actuated position to effect said sliding movement of said plurality of friction elements and said brake discs;
• and
• a primary electric actuator mounted on said non-rotatable support structure adjacent at least one of said plurality of friction elements and operative when actuated to move said piston to an actuated position and to slide said plurality of friction elements and said brake discs into said frictional braking engagement with one another.
