I sold my 66 D100, and have regretted it ever since, so I'm looking to buy a 68 D100 for sale locally. I was looking at the pictures and noticed something weird. I've attached a picture: it shows a flexible hose used to connect hard line coming from the master cylinder to hard line coming from the brakes. Anyone seen a setup like this? It can't be factory, can it? The brake down lines look like the type of OD green hard line you buy at Napa, etc.

Its an owner mod, not factory.

I took a pair of those flex lines off a Sweptline I parted out a long time ago, it also had them at the transmission cooler lines at radiator. I figured they were custom made also.
On H1 Hummers they do a similar set-up but braided stainless, they still fail due to cracking of the stainless hard line attached

the 63 - 68 parts book does list a flexible hose at this location, but I don't remember what years or models. I don't know about the rest of that setup.
I'm not at home where my parts book is, and I never can remember where it is on this site

I have had several trucks with that same setup. They also used them on the clutch line. They are factory.

that is how the 1 ton and up and the 4x4s came. its more HD than just a coiled up hard line. flex between body and frame is needed . its just like the clutch slave hose. same reason

I have this setup on my truck and the small flex hoses are leaking. Anyone know what hose size those are? I ordered what is suppose to be the correct size for my truck (‘68 d200) and they are way too long and have the wrong connectors.

Some pics from the Factory 63-68 parts manual. Looks to be factory.

Just in case this might help you, here is what I ordered from rock auto, trying to match the parts manual:

https://www.dropbox.com/s/yopz5g0utpgpd ... o.pdf?dl=0


1924312 matches the part number in the manual, but I have no idea whether this will fit. I don't have a hose there on mine, just a loop in the line. No, I don't know why I ordered it either.

Thanks guys!

Hmaynord - how long is that dorman cable? It looks a bit shorter than the ones on my truck.

I returned it so I can't measure it.
one of the links in my post yesterday has rock auto stating 5.9" From the photo, that seems in the ballpark.

Given that my lines to the splitter look terrible and rusty, is there any reason I can’t just replace the whole length from the cylinder to the splitter with steel lines or longer hose? If so, which is better?

You can eliminate rubber lines. Just put a curl into new steel lines. More rubber lines you have , The better chance of failure.

you have to have flex in the system. the 4x4s and 1 ton and up vibrate a lot more than lighter trucks so the coil style ads some flex but not as good as the rubber hoses. hard lines only has potential to crack. I like the rubber hose design better. looks better too. should be the same one on the clutch line as well at the slave cylinder

My 66 has had hard lines since I upgraded to dual braking 40 years ago. Same lines in truck today. Truck has extensive off roading back in the day with those very same lines. A coil in line is all that needed. My old 76 W200 did not have coiled lines. I off roaded that truck for 10 years and never had a line failure. In fact none of my previous Dodge 4x4 trucks 77 W100,76/79 Ramchargers , 71 FARGO(No rubber lines) W 200 in the last 43 years have ever had a line failure in that area. Rubber is not needed in that spot if lines are allowed to flex. Even my 96 W350 (3500 series) Deisel Club Cab has had its fair share of Forest Service roads. It doesnt have rubber lines in that spot.

Not a whole lot of flex between the frame and the firewall since they are (supposedly) bolted tightly together.

Great! What size connectors do I need for the master cylinder and the splitter?

You could always take your rubber lines to a hydraulic shop and have them re-made.
