Topic: 67 K/H calipers

[cmfuser01]

Kurt first thanks for the pictures and some dates from the brake lines themselves

Earlier in the thread we discussed the possible change over point or range at least for San Jose and I offered the example with the projected Dec 15th date which I feel pretty comfortable based on other cars around the same time using the early style up to that point. Now looking at what I have I worked from the late version towards that December date yesterday and found the following

The earliest production dates (real dates this time) I found for San Jose was December 21st. I must report that I would not normally offer any of these examples individually  since each has been "restored" or played with in the past, but the fact that I could, after all these years, find a group with all the same style calipers. The random chance that some prior owner made each made the same choice for replacements, if they all were even replaced, seems to be unlikely  so I'm taking the calipers at face value and giving the finding some value in our discussion. 

Inviting opinions on this observation and conclusion at this point.

Though this does not help the date at the other two plants it may suggest that it was at a similar time period and may guide us to at least start in December lookign at those examples

Digging up this aged thread because I think it might be germane...

I too have calipers like those posted in reply #16. Mine is a 10/20/66 SJ build date. Stampings are 270-6 and 76(maybe 8)544LH, 7/16" inlet.

Thoughts?

MORE STATISTICS for those who are keeping track.
11/2/66 built in San Jose, Early style calipers, photographs, date codes and as an added bonus, engineering number & date codes from original brake hoses...See attached pictures (posting within a few minutes of initial reply)

Casting numbers found on BOTH sides: Look to be 56877 on inner & H66082 on outer
Type 1 (67 gta289's pdf file bottom of page 1 of thread)
HAS 7/16" fine thread inlet lines
LH date code 189-6- (July 8, 1966). 
RH date code 217-6- (August 4, 1966)

Brake hose engineering numbers (same RH & LH) C7OA-2078-D date codes both are 20-10-6 (October 20, 1966)
Also. FWIW...All of the numbers found on my hoses wrapped around the extension tube of the hose, not linear as others have pictured

What color finish or would best duplicates the finish of the 4 spring clips that snap into the black brake pad plate (earlier design similar to the 65-66 style)

AND I also could use a confirmation that the "silver plating" (paint) is not on the machined surfaces of the outer caliper housing (w/Styled Steel Wheels)

Gun blue would work best for those.

Yay me commenting on a three year old thread. 

I'm curious if anyone familiar with 67 Cougars has noticed similar early to late K/H caliper change ups on their Cougars or if Ford/Mercury just made the change to the late 67 style with the Cougars?

Would expect that the practice was the same as on Mustangs. Day or week of change over would be the same period as Dearborn built 67 Mustangs

Here is a pic from the K/H "Disc Brake Service Manual For American Automobiles" that shows an exploded view of the 65/66 and 67-69 versions. Since these calipers were used on other cars it shows extended coverage beyond Mustangs.
(manual dated July 1970)

Manual doesn't take into account the early 67 usage of the 65/66 style. No big surprise.

[Bossbill]

Right, Bob.
This was a K/H service manual for K/H, Delco-Moraine, Bendix, Budd on many car manufacturer lines. Sort of a Motors Manual for disc brakes put out by K/H.
At the time Mopar was also a user of the 4 piston. And others.
I believe the model year designations were for the K/H model year changeover and did not account for the stock the manufacturers like Ford would have on hand.

There is not much information on K/H calipers and their casting numbers. I was looking to see what data I had and what calipers I had. I just pulled out my 65 disc brake calipers and found out they were actually 67s with 67 hoses and piston seal designs. They also had the reinforced bridge.

Makes me wonder what casting numbers my Shelby should have.

[Bossbill]

There are so many K/H caliper threads, so I choose this one.

Anyone recognize this outside caliper? It's the only I have with the K/H logo and all on the front.

Another example of a brake hose date. C7OA-2078-D part number, dated 05 12 6. Day/Month/Year seems most likely?

Yes pattern does match the one identified on pg 13 of the Date Code article I did in the Library used on later brake brake lines in an illustration shown there

Didn't think there would be so many variations of the five digit number on castings!  Thanks for all replies and photos
