Problem on the page with downloads (robots.txt enlisted pages still show up in search result)

[satm83234586]

This is the content of the file "robots.txt" that I created that in theory tells google robots not to show in the internet searches the pdf that is hosted on the page.

User-agent: *
Disallow: * .pdf $
Disallow: * .rar $

but it does not work, it finds them the same, I change the name to the pds, I upload them again to the web page and to the ftp and after 20 or 30 days I find them again.

It might help to not throw in extraneous spaces. You know, in the computer world spaces are valid characters, not just hot air to be ignored.
