Does anyone even make them to replace the rubber ones, and will this be a noticeable difference in braking or is it not even worth it?

 

Unless you have a show truck or do some extreme offroading, I would just use regular rubber hoses. If you do have a show truck or extreme 4x4, lets see a picture.

 

What torkum said. There is a shop here in Tucson, AZ that makes brake lines so I went there to check prices. The man said he would gladly take my money but unless you have a need for longer lines the new rubber lines are made so they will not expand like the older material.

 

alright, thats what i wasnt sure of, if the rubber expanded while braking, thanks
