Original Brake Hoses for '69 Z28

[Danzo]

Hans L please pm me. Thanks.

I bought two fronts from NAPA. They were really close to the originals (both originals failed within weeks of each other  - plugged closed).

[69Z28-RS]

What caused that to happen Kurt?

[dannystarr]

Maybe the fluid had some sort of a content that broke down the rubber. How could this be.. ?  They KNOW what's out there before they develop/design parts.
Maybe take one and fillet it like a fish and inspect the interior. Scratch the inside wall and see if it's breaking down?.. D

I bought a complete set (front and rear) from Napa as well, and they do appear to look very close to the originals that are still on my car.  I think they'll work just fine.  Even though the brakes still work, I'm not even going to think of attempting to drive it on those original hoses.

Same thing happened to my fronts when I went to bleed them before I started my resto.

Collapsed brake hoses are common, and often overlooked as a source of problems.

Are you fellas speaking of OLD brake hoses?  or NEW?   I understood Kurt to say he had that problem with new brake hoses... I assume you aren't speaking of NEW (but maybe 40 yr old stock) brake hoses....?

Yes Gary. OE brake hoses were what failed.

Going back and reading Kurts post.. where he stated... "I bought two fronts from NAPA. They were really close to the originals (both originals failed within weeks of each other  - plugged closed)."...  I guess I read it too fast and thought he said that the new ones failed....   rereading..  it's more clear that he bought NEW ones BECAUSE the old/originals failed.. (which makes a lot more sense).. Sorry for my misunderstanding!

For reference, here's what the original brake hoses look like from my 04B Van Nuys Built Z:

Sub Frame Fitting - note the crimping style is different than current DOT requirements:



Caliper Block Fitting - again crimping style differs from current DOT required hoses:




Note the lettering/markings on the hose line in red font:



Note the faint red stripe along the other side of this brake hose:

Reproduction hose installed - note hose crimping styles differ from originals.

I replaced my originals a year or two ago when I went thru my brake system (my originals were actually in a bit better condition than yours Hans!)..   .. but my car had been stored in my garage since 1980. 
Anyway, 1969 originals were 'single crimped' whereas newer (current) safety requirements require 'double crimping' on the ends, so your new 'reproduction' hoses may have reproduction markings, but will have double crimped ends (for safety).  I bought new hoses, but not the expensive reproductions, as I can't see that sort of expense simply to maintain a vehicle in functional order (my car is unrestored).

Makes total sense.   You can see why I didn't re-use the ones on my car!

Thanks for the information George .. and Sixtynine...  Those certainly appear to be more accurate (but with the additional crimps)..  and more expensive.      I'll consider them strongly.
thanks! 

I had a set of NOS brake lines Gary that looked the part except for double crimps and had them stenciled as George showed for our restoration. Just another option if you have some laying around....

Do you have photos of that stenciling, chick?    Who did/does the stenciling for such items?

Yes I do in my build thread somewhere but will check and post a picture. The guy that did mine was the same guy who George bought his hoses from as he's from IL and he used to sell them on ebay. I contacted him and he agreed to stencil my hoses I sent him.
