Brake line positioning?

Hello,
I will be purchasing a complete set of steel brake lines for my 71 Challenger in the near future. I will also be installing factory front disc brakes placing the calipers towards the front. There have been questions on this and other forums regarding positioning the front steel brake lines either over of under the front frame rails. Because I'm doing the disc brake conversion (using factory Mopar parts), what is recommended for steel line positioning? I assume this has something to do with caliper rubber brake hose routing? What is recommended for my application? Also, I was looking at Inline Tube for purchasing the steel lines. Had good luck with their transmission lines. Any recommendations on a vendor?

Thank you,

Tirekickertoo

I used stainless lines from “Fine Lines” for my Challenger. I bought them directly from them at the “Mopars at the Strip” car show in Vegas. They fit great and no leaks. I would not hesitate to use “Inline Tube” either.

As far as routing goes, I believe they will line up very well with the factory position, and it would be hard to change the position of the stainless lines as they are bent specifically to go around the frame rail. In this mock up pic you can see the front mounted caliper, and the armored line pre-bent around the frame rail. I also included a pic of the confusing lines from the proportioning valve. Disregard the hydraulic clutch.

I think the lines went under the frame on 70's and over on 71-74. I have used Inline Tube and Right Stuff Detailing. I would definitely recommend Inline Tube, and would never recommend Right Stuff for anything.

My 73 wraps under the frame rail and connects to the bottom of the hose bracket.

Hi Adam, Old B5, and Rich G.
Thanks for the reply's and pictures. Since I am converting the car to front disc brakes, I plan on ordering steel lines from Inline Tube. There seem to be an ongoing debate on what Mopar did for positioning the front brake lines either over or under the frame rails? Not sure why at this point but I'll eventually find out. I'll order the brake line kit stating the car already has disc brakes. I already purchased an original disc brake master cylinder and proportioning valve, so I hope the area of the car will be a non-issue. Thanks again for the help and stay safe.

Best Regards,

Tirekickertoo

I know this is an old thread but had the same question and for the years 70-74 as ordering says to check your specific car for routing. Could it be that if actually has to do with the brake setup as in front Disk as apposed to front drums? If I can’t figure this out I to will just move forward and make my own.
