I do not think they need any correction. However, I would understand each one this way:

  1. … if you like = if you like it. (the brochure)
    1a. … if you like to = if you like to take. (the brochure)

I would not interpret those sentences in the way Anglophile does.

1 = Take one of these brochures if you (would) like (to do so), etc.
