Brake line fab?
I was wondering if I could use hydralic hose to replace short sections of brake hose on my 70 4x4 dana 44 front differential.
And would heavy duty hose clamps hold the pressure if one is put on each end.

I wouldn't recommend it. The pressure in those brake lines gets pretty high, and the crimped hoses are designed to withstand that kind of pressure. You'd be mighty disappointed if your homebrew lines were to give out while on the road. On the other hand though, occasionally I do run into some A/C hoses that are put together with clamps, but I think that there's something else holding them together as well.

Steve.....I would replace the line and not have to worry about it...or a quick fix would be to get a short piece of line with compression fittings and fix it that way..... the rubber hose and clamps is not a safe bet.....

Would using steel lines soldiered over the brake area work
also isnt hydralic hose rated at like 8-10000 psi and if manual brakes get higher than that then we have a problem

speedking100,
There are no short cuts to doing a safe job, especially if you have to share the roads with other drivers or people on sidewalks
Hydraulic hose is usually rated to 3000-4000 bursting psi. Not 8-10k. Though that does not mean it is rated for flex, abrasion, or constant use. Especially the connectors. Also, working pressure is different than bursting pressure. DOT approved lines are usually comprised of at least an inner and outer layer with sheathing, are designed for constant flex, etc.
That being said, I have to assume you are looking at these because you either do not have the money or can not locate the lines. Search about three months back, I posted about replacing the hoses on my F-100, it contains all the NAPA/Autozone numbers for hoses and adapters. Total cost will be about $50.00.

Steve,
Are you talking about fabricating the flexible brake hoses for the front brakes? I know of a place that you can get custom made new brake hoses. I had to use them because brake lines for a 70 f250 4x4 were impossible to locate. There is a place in Trenton, NJ called Trenton Brakes that did mine. The brake hoses fit like a glove.
I also agree with the others that you should use the proper brake components for the job for safety reasons. Its more important to be able to stop than to go.

Thanks for all the replies, I was just feeling out the subject although I fully realise the fact that there are no short cuts to do something as important as the brakes. I also have very little money, so after the brake repair I will have to drive as is for a while untill I get some cash
thanx again
