Title: kelsey hayes caliper discrepancies and red color found
Post by: evantugby on February 11, 2018, 01:32:40 PM
Here is a set of KH calipers with casting #58977 and both stamped with 1B. Not sure what that means. 

Note:‎  Take a look at the two differences‎: #1 the bolts and #2 one has a secondary casting number A56982 (I think) while the other caliper with the larger bolt heads does not have a secondary casting number.

What is going on with these two differences? 

Also, would they have had a red paint mark on them (last picture). I see faint red color on the top. 

Thanks,
Evan

I have not found a red marking on them before. More likely it is a paint left over from a previous rebuild or the like. What car, engine , time frame are you building the car to look like. I have heard about a clone Shelby and various other things. The calipers had a certain look depending upon when they were made and what kind of wheels were being used. That is why the info is relevant. You should get used to supplying that information in your signature as a default or supply it if asking about another .

I thought my signature block was visible to everyone. It shows the partial vin and build date. Is it not visible?
I have a 6T09K13. I want it to be almost as good as when it rolled off the factory on 23 Oct 65, except, it will have a gt-350 paint job, tachometer and GT6 10-spoke wheels. Here is a picture of the kar before restoration. The kar was beautiful on the outside and inside but the underside had been mostly neglected. Some pics attached. Therefore I am making it as perfect as I can make it with the help of gentlemen like yourself. But I'm a guy that really wants a Shelby GT350 but can only afford a k'code budget.

So with these particular calipers, could you tell which wheels my kar would have came with? I thought another post eluded to that presumption.

Can anyone identify the discrepancies noted in original post? Also, can anyone direct me to instructions on how to rebuild these calipers?

Letting the people commenting on your question requests know what you are doing is going to get you the best results. There are various differences between a 66 Mustang and a 66 GT350 for instance.You should consider amending your signature to reflect your intentions of making the car like a 66 GT350 . It is best to not assume everything is the same which is why the amend to signature suggestion for best results.   Without going into a lengthy evolution of the calipers the inside half was cast iron and the outside half was silver ether zinc plated or sometimes painted no smudge aluminum silver from the factory. Earlier versions would be different based on wheel options. The pad retainer plate was semi gloss black.

Ok, decided to dive into it. I disassembled, wire wheeled, soaked in evaporust for 5 hrs, rinsed and dried. Here is a comparison picture. Notice both halves are the same cast iron. I guess that means I had a styled steel wheel and not a deluxe steel wheel, correct? 

Reference: http://www.concoursmustang.com/forum/index.php?topic=3875.msg21191#msg21191

Before I reassemble, please advise what protective coating these should have for my metuchen built 23 Oct 65 kar. 

Thank you!

what do you mean by "deluxe steel wheel"?
Title: Re: kelsey hayes caliper discrepancies and red color found
Post by: evantugby on February 11, 2018, 10:27:49 PM
I mean deluxe wheel. But after further evaluation it appears there is a difference in the two halves so what can we conclude about the wheels my kar came with?

I have read from a previous old post that Bob Gaines said "In 65 both half's were cast iron if on a steel wheel car and the outside half plated if a deluxe wheel car."

So is it safe to assume part of my caliper is plated and would have came with a deluxe wheel?

Early 65 you had calipers made ether with both sides cast iron (for steel wheel cars) and another style that was inner half cast iron and outer half silver for cars with deluxe wheels. I believe by later 65 production Ford had decided to make all of the calipers with the silver outer half regardless of what wheel. There were other internal changes (different boots) that evolved as production went on. In your case at the very least I believe the calipers have been rebuilt before. They may have even been exchanged with another pair given that has been a common auto part store practice to return a core when a rebuilt part was purchased.

I believe I found somewhere and I will have to try and locate it again that the 12 point bolts were used on 65-66 calipers and they switched to the hex head bolts in 67.

Jim Cowles would know, he's rebuilt/restored a ton of these.

Later in 67, yes. Early were 12 points

Jim knows the evolution of these calipers better then anyone I know. Among other things he has identified numerous different seals used during the evolution .

A point of reference. The MPC, Section 21 pg 2, indicates that 378773-S2, a 12 point head drive, was used in 65,66, and 379027-S2, a hex head drive, was used in 1967. No "early", "late" or changeover date reference was included.

I don't disagree what the Ford book might say BUTTTTTTT the real world is sometimes different as we have learned from other examples. As Special Ed (Meyer) likes to say "That's just the way it is" .

It was true at least until November 2nd 1966... My original date-correct, example pictured below

+1 or is it 2.  The MPC or that version of the MPC is  incorrect on this detail

We've shown  unrestored examples of the detail in a number of prior threads

I'm in contact with Jim Cowles.  He did mention I have a 65/66 and a 67 caliper.  He is going to square me away on what I should have.  :)

These are the stories I discover where I wish the kar could explain to me why or how...

The boots for the pistons are very much different from 65/66 and 67, as are the pistons, IIRC.

Have you found any date codes on the calipers?

I found one on the 12-pt bolts. Decoding I think 265 day of 1965 which equates to 22 Sep 1965, about one month before my build date.

Casting shows 284, which would be Oct 11, 1965.  Remember that the date on your door plate is a 'scheduled date' and can be off days/weeks before or after.  Other dates on sheet metal and on components throughout the car can usually narrow the date down to something more realistic.
