Hi guys,

I've almost got my '41 convertible converted over to F-100 brakes on the front. Everything was working well until I went to hook up the brake hoses. The original '41 brake hoses will not screw into the F-100 brake cylinders..., the male threads on cylinder end of the '41 brake hose are too big (I think 7/16 vs 3/8). And I can't use the F-100 brake lines, because it's a different female threat at the end which hooks up to the steel line. What to do? What to do?

I know there is somebody out there who has done this same conversion. What brake lines did you use? Do you have a part number I can reference. Did you use an adapter?

i haven't had your particular problem, but had a similar mismatch at the master cylinder. There are "inverted flair adapters" as a solution to the mismatch at the flared connection at the steel tube end. I found some at Autozone and some at NAPA. You might have to look in the Weatherhead fitting assortment yourself, most counter persons give you a blank stare. Someone told me that Ace hardware carries them.

Autozone will have the adapters.

3/8"-24,cyl to 7/16"-20, hose

Richard Lacy at the Early Ford V-8 Garage has the correct hoses. I don't have the part #, but that is where I got my hoses when doing the conversion.

Henry, Go to NAPA get a Napa #16179 hose, That is what you need no adapter needed. I just put the f100 brakes on my '40 pickup. Have a great night!

Fantastic! Thanks all for the quick responses. I'll be putting the brakes together tomorrow!

Tough call, $50.00 for hoses or $7.00 for adapters.

OK guys,

I finally got the F-100 brakes hooked up to my '41 convertible, and they work great!

Henry, thanks for taking the time to post those part numbers, I'm sure they will be helpful to someone some time.

Though the 450461 (spec'd for 1.5" shaft) has been the traditional seal to use for the F-1/F-100 brake swap; a National # 473441 seal is a better fit on the 1.562” early Ford spindle.
