brake lines for disk conversion?

I'm doing a front power disk conversion on 63 with POL conversion kit.
At the time when I ordered the kit I did not order brake lines. (I thought it would be easy to bend my own and use existing lines) but now I'm stumped as to how I will hook up rear brake line.
Anyone here used existing lines and connected to a disk conversion?
kinda hate to shell out another $90-100 for lines.

I bought CPP prportioning valve and ran them from there. Bent my own lines, It was really pretty easy.

Having a hard time visualizing how to route the lines.
The rear brake line comes up to front of truck on the passenger side
Anyone have pics?

Re: brake lines for disk conversion?

CCP has a rear axle clamp for a brake T, I think the part number is RFH-TK. After cutting off the panhard bar bracket from the rear end I moved the brake T to the drivers side of the axle tube. I will be running my rear brake lines down the drivers side of the frame. I'm using rear discs as well. I purchased the rear panhard bar kit from Early Classic that runs from the drivers side frame to the passenger side trailing arm.

Like many jobs, it will cost more to make your own due to the cost of bending and flaring tools but if you ever need to do it again, you will come out ahead. The added benefit of doing it yourself is that you can put the lines exactly where you want them. The pre-bent kits are made for either original replacement or their kit that may involve their booster/master.

Re: brake lines for disk conversion?

Some pics of the home-made route (but bent to mimic the original routing, at least somewhat) in this thread: http://67-72chevytrucks.com/vboard/s...d.php?t=487384

Keep in mind that these pics are for all-drum system, and, therefore, the 1/4" lines all the way around. On a disk/drum system, the front disk system should normally be 3/16" (i.e. a bit smaller diameter). You can use the existing 1/4" you had, but if replacing, best to use what the system is designed for. If you don't you may need an adjustable propr valve in order to ensure you're using both the disk and drum system most efficiently.

Re: brake lines for disk conversion?

Believe it or not it's not to difficult to bend your own brake lines. Auto Zone & O Reilly's both will rent you one for free. The link that jocko posted is a very good write up. If you're unsure of yourself take a few old coat hangers straighten them out and practice your bends on that first before bending your brake lines.

Me, I went a different route. I'm the laziest, cheapest SOB you'll ever meet in your life. I kept ALL the brake lines, vacuum booster, proportioning valve etc from the donor 73 truck and was able to re-purpose everything. I did however have to make a bracket to mount my proportioning to. Again I used a piece of coat hanger to get the correct angle before making my bracket.

Re: brake lines for disk conversion?

I would use Cunifer brake lines... Look it up. It's a copper nickle alloy that is wonderful to bend and has a cool color to it. Since I've used it, I will not go back to steel.. Summit racing has it Clicky
