Page id only breadcrumb trail

So I am trying to configure my breadcrumb trail to page id only, I have an example of a website which I want to mimic but I am finding the breadcrumb trail php too difficult to edit.

The website I am trying to mimic is: http://fourdrubber.com/

and the code for my breadcrumbs are as follows.

if ( ! function_exists( 'presscore_get_breadcrumbs' ) ) :

	/**
	 * Returns breadcrumbs html
	 * original script you can find on http://dimox.net
	 *
	 * @since 1.0.0
	 *
	 * @return string Breadcrumbs html
	 */
	function presscore_get_breadcrumbs( $args = array() ) {

		$default_args = array(
			'text' => array(
				'home' => _x('Home', 'breadcrumbs', 'the7mk2'),
				'category' => _x('Category "%s"', 'breadcrumbs', 'the7mk2'),
				'search' => _x('Results for "%s"', 'breadcrumbs', 'the7mk2'),
				'tag' => _x('Entries tagged with "%s"', 'breadcrumbs', 'the7mk2'),
				'author' => _x('Article author %s', 'breadcrumbs', 'the7mk2'),
				'404' => _x('Error 404', 'breadcrumbs', 'the7mk2')

endif;

my site is not live and only just in the interim of being built – no content etc,

but the breadcrumb trail is displaying archives and categories which I just plainly don’t want to display.

Kind regards
