Topic: 67-69 Rear Brake Hose (w/bracket)

[Bossbill]

I believe the title is correct in that this rear brake hose/distribution block  is used through 69. If not, let me know.

I am restoring my rear brake hose/bracket/distribution block.

The first pic shows this block with its C7ZA-2A448-B marking.
It appears to be a brass block and the hose crimp is also non-ferrous.

The MPC lists the replacement rear brake hose as a C7ZZ-2282-B. Unknown to me why the number changed.

I believe the end that attaches to the chassis should be gold dichromate. The bracket that attaches via staking to the brass block is also gold dichromate.

I'm looking for the number that appears about mid-span on the hose. It looks like I have a red-gold stripe, a number in the middle and then another stripe.

Is that right? So, what should that number be? The color?

[no, I have not done the plating on the end hose connection yet]

Bill,
They did use that hose from 67-69. The hose you have pictured is for a early 67 car the hose date is November 29th 1966. The number on the brass block is the engineering number the part number you list is correct for the hose. They later changed the engineering number to C8ZA 2A244 A but part number stayed the same. Most early 67 hoses were white ink & different DOT numbers on the hose. Sometime late 67 early 68 the ink changed to red & DOT numbers changed to A/V-1/8-8396??-C 05019-SAE 40R1? this would be repeated along the length of the hose. The C is shift 05019 is January 05 1969 this number of coarse changes based on when it was manufactured. On the opposite side of the hose are red stripes broken up along the length of the hose. I am told this is so the installer can make sure there is not a twist in the hose. You are correct the bracket on the brass block is zinc yellow dyechromate as is the end that attaches to the body bracket. Hope this helps.

They didn't change the number.  The number stamped on the block is, in Ford documents, called several different things in different settings including "part number", "identification number", and "engineering part number".  Considering something as simple as this hose (technically a hose assembly), in order to manufacture it there are at least three distinct items that would need to be ordered.  Each of those needed to be engineered, tested, tracked in multiple ways including costs, sourced, etc.  To do all of that each needed a number.   From a service perspective, they only serviced the complete assembly.   The basic part number of the block is 2A448, the hose is unknown, and the flared fitting is yet another.   The service basic part number is 2282, but again that is the the whole enchilada.  There are books that provide a cross reference from the identification numbers to the service part numbers. 

They later changed the engineering number to C8ZA 2A244 A but part number stayed the same.

I would say that the 2A244 block was modified and was assigned a new item number, but Ford decided to keep the hose assembly service part number the same.  These days that sort of thing would not fly, makes it impossible to track any warranty and even more important safety issues.  IMO the assembly should have been assigned a C8ZZ part number.

David Davis -- thanks for the details and pics. I appreciate that.

It's interesting that this dated hose is on my Mar 67 build. I doubt it was changed as so little on this car was messed with. It's odd, isn't it, that my early block has a later red lettered hose?
I'll try and duplicate all of that on my hose. Should prove a challenge. 

John -- Ok. I admit I got caught in the part/engr/ID number bit. Thanks for the heads up on how it really worked here.

Bill,
I have seen some rare examples of a hose predated by that much & was original to the car. Typically its 30-45 days but there is always the exception. Its also odd to see an early hose like that with the red ink & later DOT mandate. I have many many original samples from 67 cars that have white inking & different DOT mandate numbers on hose. So that is definitely an odd hose but appears to be original.
67gta289,
All Im saying is the early to mid 67 cars had C7ZA-2A244-B hoses & later they all went to C8ZA-2A244-A not sure why or exact time frame. The brass  block & hose look the same other than the ink color & DOT code or mandate. Which may be why the engineering number changed.

Back with more info. I thought I had a decent description, but I guess not.

Although the stripe is a red/gold it does not have the DOT markings.
The best I can make out is that there is a:

triangle (base down, tip up) and then a 2 5 0 8 0  ?  ? ?
then perhaps another triangle base up, tip down

with stripes on either side of these markings. The first three letters I believe are accurate ... the rest, not so much. There may be 3 letters after the 25080.

The color is very close to this 67 Ford full size brake hose (pic). This is a sample of a 67 NOS part and NOT what's on my car.

On the other side are 4 stripes of 2.5" long with 0.45 between the stripes. Some of the stripes end under the crimps.

Any help with this better description of what I have and what the numbers might be?

[69bossnut]

Bill,
It?s not a triangle. It is an A25080 (shift A 25th August 1970 if that last number is an 0) but I would suspect the last number being a 6. That would make the date on the hose shift A 25th August 1966. The 3 letters after are SAE. The first hose pic you post is shift A 29th April can?t see the last one. But the date on the brass block is normally 30-90 days after the hose date. The pics I posted were taken and made from a NOS rear hose dated March 68. The date in the hose I had made is shift C 5th January 1969.

That makes perfect sense because the DOT did not become law until January 1, 1968 which resulted in lots of changes to lots of parts of every automobile. Your hose would be typical of a hose made for use in a 1967 automobile.

Right you are.
I was going through the restored pic section and not finding much. I then found a post regarding when DOT was created. Not sure if it was here or on the web somewhere. This lead me look only at pre-68 hoses and widening my search to all Ford car lines.
When I saw the full size hose I tried again and took a magnifier and an alternate light source to my hose.

Thank you, David.
That is really useful information and specific to my -- and perhaps other's -- restoration efforts.

This hose has been an on and off again project. It was first cleaned up and the staking undone quite a while ago. However, I had not yet mastered plating so I put the hose in bagged storage. It was only after a successful plating effort on the parts and a new stamping system I bought this last month that I brought all the parts together.
