brake lines

[spr85gmc]

I know there is a number of thread on running new brake line but many of them have different info so to be sure i decided to ask the question again for the hundredth time.... On my 66gmc short bed I am doing a five lug conversion using a 77gmc long bed for parts. I have already assembled the suspension and relocated the perches on the rear axle just need to weld them in... so now on to the brakes can I use the metal lines off the 77 and just shorten the lines goin to the rearend or should i just replace everything? Can anyone point me in the right direction of the size brake lines i need along with tips and recommnedations to ease this process. thanks for your help guys.

As long as the lines are good and clean, use 'em. I wouldn't spend anymore than I have to as long as the stuff I have is servicable and up to the task.

As Martin said reuse as much as you can, you can aways replace later, except for the rubber flex lines replace now, it will save you a lot of grief, 3/16 lines are used as standard anymore.

X2 on replacing the rubber hoses. They can deteriorate from the inside out, so they may look fine on the outside, and be depositing debris inside the rest of your nice clean system.

If you choose to replace the lines, do some internet research on the new "green or black" hand bendable stuff that most of the chain parts stores carry exclusively. I have professional bending tools and prefer the old galvanized tubing. Some people love the new stuff (I'm not one of them). It's just worth doing some checking ahead of time so you don't end up buying something you're not happy with.
