had the same problem. did not find the reason why it doesn’t work.
fix this problem by custom code:

add_action( 'content_single_product_show_this_brand', 'show_this_brand' );
function show_this_brand() {
global $post;
if ( is_product_category() || is_singular( 'product' )  ) {
$taxonomy = get_taxonomy( 'product_brand' );
$labels   = $taxonomy->labels;
echo get_brands( $post->ID, ', ', ' <span class="posted_in">' . $labels->name . ': ', '.</span>' );

/* if you want to show brand images
$t = wp_get_post_terms( $post->ID, 'product_brand' );
foreach($t as $tid){
echo get_brand_thumbnail_url( $tid->term_id, 'full' );
}
*/
}      }

*put this into the functions.php
now I can do this action everywhere I want (within archive-page or single-product-page)
do_action('content_single_product_show_this_brand');
