Am concerned the stock brake hoses I purchased are too short. Have been in touch with Cass at DrDiff and his are no longer than what I have now. Has anyone used and can provide source for aftermarket front brake hose longer than 15.6 inches?

you can buy all sorts of various length hoses on ebay. I've used a few on jeep builds.
Cass has previously recommended '69 camaro disk brake hoses if you have a 67-72 car and have run the calipers to the rear. Those range from 15.7" to 15.9" depending on the manufacturer.
But if Cass sells hoses that are 15.6" I imagine those would work just fine. The difference in his stainless braided hoses vs what you have now is there's no hard pipe on the caliper end, so the hose would take a different path than what you have there.

Guess I should have mentioned this is for 73+ with slider calipers on front. You are right and did consider that the hose would be turned away from knuckle which would give me some valuable room. Thanks for responding.
I need 7/16 banjo bolt fitting on one end and specific termination at hard line. That's a lot of looking. Thanks for response.
Go to a hose shop and get one made. Make sure the hose shop is DOT certified.
motorcycle shop maybe?
Then the DoctorDiff hoses should fit fine, I ran them on my Duster when I still had slider calipers on it. Pretty sure the sliders went to the front from the factory.
I just assumed you needed the longer hoses because it was a 67-72 converted to 73+ brakes that were to the rear. If it's a 73+ with the 73+ brakes to the front the factory hoses should fit fine, could be that your particular set of hoses was just made too short. The length does vary a little bit by manufacturer, and it wouldn't surprise me at all if some manufacturer tried to save a buck by shortening the hose.

Fwiw I never saw ay appreciable benefit to the stainless hoses.
Most of the time we just grabbed a regular rubber brake hose. The paper catalog had fitting sizes and showed what brackets were on the hoses.
We modified a lot of them also if needed.

Well order set of hoses from DrDiff as you suggested. Dame it though. Just go the existing banjo bolt connections to stop leaking.
Was headed down that route using Pegasus as a supplier but decided to try DrDiff. Thanks for responding.

Can’t remember to be sure but doesn't the feed and hose routing usually go closer to the upper ball joint/control arm top of the caliper? If you swapped calipers side to side the feed would then be at the top and your hose wouldn’t have to stretch as far to get to the input/connection. You may have just mounted the calipers on the wrong side
They last significantly longer than any of the rubber hoses made today, and expand less under pressure for more accurate braking.
The bleeder is on top, the hose typically goes on the side. Putting the caliper on the wrong side usually means the bleeder isn’t the highest point, which causes issues bleeding the brakes.

I agree, which is why I think he may have his/them reversed.
The one you’re showing there is the better design for later diplomats etc,
but I think he may have the ones which were initially spec’s and designed for stock 73 and up A body like pictured which is and can be a pita as you mentioned the bleeder and inlet are on the same side. I always buy the diplomat style ones for my conversions and usually rear mount them to avoid issue with 72 and lower sway bar styles. I’m pretty sure the stock 73 a-body set up had the hose location on the top (closest to the hood) of the caliper from the factory
Right, there’s different versions of the caliper. But his calipers are to the front, so he shouldn’t have any issues running 73+ A-body calipers because he’s running the stock 73+ arrangement. His picture doesn’t show the bleeder, so I’d just be guessing but that brake pipe isn’t on the other side of that caliper.
DoctorDiff sells the calipers with bleeders drilled at both locations.

I’ve bought the D-diff ones before.
You can have anything you want made at Earle's Service shop on Gasoline Alley in Indianapolis.
All the braided hoses in NHRA Top Fuel & Funny car are required to be certified to withstand the give pressure after assembly, and have a metal band tag attached to them to show it.
I am sure the other makers offer this service, but I am only familiar with Earle's
Good luck

This is the orientation of stock 73 a body disc brakes. What I’m trying to say is if he has them reversed and banjo bolt hose connection is at the bottom they are likely being stretched too far. Not to mention looks a little dicey with its proximity to the lower ball joint and parts that are in motion down there. At the top is has the least amount of deflection throughout the steering range
Origina intent was to mount calipers at rear but lower ball joints were machined in such a way that prevented that. Sounds like I did not swap parts correctly but was not the case. That's why their mounted in front. Thanks for responding.
Thanks for the great info Tom and for responding.
Thanks for the response and pic. The calipers are mounted in front as pic indicates with banjo bolt and bleeder on top.
Thanks. I have them on order.
The banjo bolt connection and bleeder are on top.
