Can anyone tell me which of these two sets of brake lines from Pelican are the better ones. One is DOT approved, and cheaper, and the other isn't approved and a few more dollars.

I guess my only question is, how dows one know if they need to replace their lines? With rubber lines, you can actually see the rubber, and you can see and irregular bulges.

check your calendar. if it's been 2-3 years, off they go. if the lines have been stressed (hung any calipers from the brake line lately?) off they go.

they point is, they -may- swell less and provide a stiffer pedal. i've run them on my cars, and i'm putting a set on the 911.

most rubber hose failures are actually in the inner liner where you can't see them either. those you replace in the event that you detect any visible external tears (not an issue with braided stainless-sheatherd Teflon) or you encounted a grabbing corner caused by inner liner atherosclerosis (not an issue with Teflon liners).

you choose a set of issues that you are comfortable dealing with, and take your chances.
