Brake duct tubing
« on: September 07, 2020, 03:45:08 PM »
What style of brake duct tubing was originally used? How was it attached at either end by SA? I'm seeing pop rivets and what looks like hot glue.

My guess would be race car brake duct tubing with wire. But since they were in an airport SCAT or CAT tubing comes to mind (which looks about the same).

Pop rivets. Hot glue was not typical from what I have seen.

I believe that the hose that was used was the duct for the defroster.

  Not defroster duct, that duct's diameter was too small.  It was some industrial grade duct that would be hard to find in todays light-weight world.

I thought on forum 1.0 somebody had sourced appropriate heavy gauge hose?

That came from Dave Mathews. He said it was defroster duct which is why it rotted out so fast.

Mustang Defrost duct? That's 2 1/2" ID.
The brake cooling hose inlet is 3" OD.

Does it look like any of these?

3"? Not according to this. These are from my 3074, and LA. What part of China are yours from?  ;)

I actually knocked a brake scoop loose a couple years ago and was kinda surprised how well they held up after all this time.Actually saved the scoop from falling all the way off.They were pop riveted...

The one on the far right most closely resembles the hose mentioned in that 1.0 thread.

2-9/16". That isn't 3" unless you're maybe measuring with your toes?

You want it in millimeters and a signed and witnessed affidavit too?

 I have a NOS kit in the SA box which I bought at Hansen Racing in Sweden more than 40 years ago. He was the importer of Shelby stuff to Sweden and his shop is still around and run by his sons.
Unfortunately the hoses are too short (don't know why) so I bought some replacements that looks different.
