Friction disks, such as rotors and stators, including floating wear liners are disclosed. The friction disks may include a core and a floating wear liner configured to contact a contact surface of the core. The cores may include a retention ring that is substantially concentric with the core and extends axially beyond the plane of the contact surface. The retention ring may radially constrain the floating wear liner in a position aligned with the contact surface to provide frictional contact with the core during braking.
