Thanks for the photo. My truck is a 69 and I talked to Bill at Finelines and he said I need the disc brake conversion set. There on the way. Hope this works cause im all out of options.

Looking at ths setup, theres line unions from the prop valve down the the cross member. My 69 has a union for the front brakes only to reach the left and right wheels. The rear line goes down, and behind the crossmember to the passenger side of the inner frame and unions there. I had to take off my headers to install these. And they still dont line up correct. Is there more bending I should be doing?

Flaring pipe isn't that bad. Being without tools myself currently,I would check if the NAPA shop can't make it 4you. A 6 foot piece with fittings and flares is not any more than $7.00 +or-. They may ask for labor charges but if this is the only flaring you need to do for the next year, it may be cheaper than buying the tools and learning the art yourself. And yes, you can use unions from front to back. Get creative and figure out how to do it with the least amount of unions. They sell them in various lengths so figure out total length and also where you want the union for ease of installation. If figure is inbetween buy the longer and adjust out the extra. David

Now we get into the bend problem. Maybe im making more of this then I should. The guy at Fine lines told me for the disc conversion, I need the $65 kit for oem and $90 for Stainless. This kit connects to the unions for the front brake and rear existing brake lines. My biggest question to the board was could we just use the brake lines from a 71 or 72 truck?

[VDOG]

Ok did the Finelines thing, talk to bill again. From the first picture you see the square bend was not next to the frame, and I did not have a shipping bend.
So I bent the square toward the frame and that solved my problem.

[VDOG]

So now assembly will start tomorrow, here are the painted parts. Forgot to include the painted headers.

[Sammy]

Don't know about where you are at but in my state it is automatic failure to use single flare brake lines if caught during inspection. Must be for a reason. I used inline tube very minor alteration for fit & reasonable with quick shipping. They are good people to deal with.

I prefered Finelines, had no problems. I order everything for a 71 w/power disc brakes. Everything worked great with maybe a tweak here and there.
The lines going for the frame to the propotioning valve needed the most tweaking but works/looking great now....WOOT I have brakes again.

1971 and 72 trucks came with disc brakes. So did you just replace the lines you already had with new one?

[Gulf Rat]

Went from no power to power brakes, so had to replace all lines coming from frame to prop valve to master cylinder. Got the master cylinder and power booster from the local parts store. Only thing I had to get was the brackets that mount it to the firewall, if you need them I have some extra's. Can also send you pictures of my setup.

Yes send me the pictures, I would appreciate that. Look at my line, you can see they were not setup for disc brakes, I had a metering block.
To make it worse, my MC is used for a car. But thats the one that came with the truck.

Unless you have a 71-2 x-member, no the 71-2 lines will not work for your application. The brake lines 67-70 are in the rear of the front x-member and 71-2 are on the front of the x-member

[Gulf Rat]

well are your lines going to the front or rear of the cross member. mine are in the rear and it's a 71.

Gulf Rat

[Gulf Rat]

Here's my rusty old 71, but as you can see lines go down to the back of cross member.

THey all go down the back,but the 71-2 go over the x-member and across the front to the caliper, the 67-70 stay on the back side of the x-member, look at the pics on this page and you will see my 67 truck with a 72 x-member and discs.

Also in the 2nd pic you posted of your 71 showing the shock up close, see the little flipped up tab at the end of the x-member without a hole in it? That is where the 67-70 hard line would stop and changeover to flexible lines to the drum. That same flipped up tab is on the front and back of the x-member, again 67-70 used the back tab, and 71-2 used the front tab.

Yes you still have to use the correct lines for the year x-member you have, discs or not. The little tabs I mentioned are on both front and back,but will only have the hole in either the front or back.

Thank you on the comments on my frame, it was a lot of work.

[twotrucks]

If you don't change the crossmember all you have to do is fabricate some little brackets to secure the transition from the metal brake line to brake hose from the caliper. I have a 68 and used lines from finelinesinc for a 72 model.

Great picture TCB-1!! If you look at this picture, you can see that TCB-1 used ONLY one of the front brake line ports. If you run a 3/16 line from the prop valve to the T located just inside the L.F. wheel that will supply the front disc brakes just fine. The other line 1/4" goes to the back.
do not be afraid of the infamous DOUBLE FLARE. It just takes a bit of practice. you can do this!!! I have a flaring kit I bought from Matco, and hated doing this until I did my last car. I made up my mind that I was doing it, and doing it well. Now it is just like scratching my elbow. Practice makes perfect. If you send me an email I will send you pics of my 69 with power disc brakes. They work, I double flared em, and it anit hard

[cparman]

VDOG, if you buy a line kit for the prop valve from Master Power Brakes, it will bolt to the valve with a little wiggeling. I really like those guys, and ask for Pat when you call . send me am email, or teach me how to post a pice and I'll show you my truck

Of course its an after thought now. I picked up an MC, prop and booster for $65 a couple of weeks ago. Got my old lines off.

The flaring tool you have is hydrallic im assuming.

[cparman]

VDOG I PM'd ya

[cparman]

my flaring tool is a plain old manual flaring tool. It does a good job on steel lines, but Stainless is a good bit tougher

[cparman]

Ok here goes. There might be pics, and there might not

I painted my master cylinder with the paint in the picture. I put 2 coats on it, letting it dry for 24 hours in between. Used a fom brush. Did this on my last car and it looked great 3 yrs later

[VDOG]

I have see those mounts. CPP has left, right, and under the MC mounts. which ever way you can get it to work. Now I need brackets for the booster.
