Welcome to the Q&A Forum

My concern is that page 1 and page 2 are redundant. They are only redundant if they are filled with identical content.  Content about brands can be sales information or information of many other types.. how to select amount their models, how to use, how to repair, accessories available, many, many other types of information - each different, each targeting a different searcher, each capable of stimulating conversion, each a candidate for producing links. Entire websites can be made from one brand, one product line, one model... potential customers, new buyers, long-time owners, service providers, journalists, and many other types of people love this type of website.

You should not have too. However if you are concerned this has not been picked up then go right ahead - it won't hurt matters. The reason I mentioned the sitemap in the last post is if your sitemap has the updated URL included, you're already submitting the index request that way, no need to manually do it again. You can also search using site: and see if the page has been indexed/updated with the new URL yet.
