Article Footer doesn't go full width

I’m using the latest version of wordpress and decode.

I noticed that the top of had a hr or line that goes the full width of the article.

Right now, the footer of the article has an hr or line that only goes 85%.

If you look at my page:
http://www.vwbusblog.com/2014/03/replacing-fuel-injection-harness.html

You can see that the article .entry-meta has a width of 85%.

I can go in and change it but I’d rather have an option or have it at 100% to match the top.

Thanks, Casey
