Remove add link for custom post type

Hi , I am trying to remove the “add” link from some of my post types. Find som code that remove the add link from de “main/side menu” but there is still a add link at the top of the page when I wiew the post, how can I remove that?

This is the code that removes the add link from the menu…

function disable_new_posts() {
    // Hide sidebar link
    global $submenu;
    unset($submenu['edit.php?post_type=footer'][10]);

    // Hide link on listing page
    if (isset($_GET['post_type']) && $_GET['post_type'] == 'footer') {
        echo '<style type="text/css">
        #favorite-actions, .add-new-h2, .tablenav { display:none; }
        </style>';
    }
}
add_action('admin_menu', 'disable_new_posts');
