Topic: 67 K/H calipers

[65fastbk]

I am thinking of purchasing calipers with the casting numbers of 71312 and 71315 on the body's not sure the inlet size...are these casting numbers for a 67 mustang?

[ruppstang]

I can not tell you about those numbers but the numbers on our SJ 11-04-66 built 67 have 56877 on both sides.

[67gtasanjose]

Likewise what Marty said, 11/02/66 had these. There is another number on the outer half, it also looks to be the same right side or left.

It looks like the castings must have been the same, then holes for lines and bleeders done afterwards.

For any qualifying information, I can say this is the first time I have ever removed (just this morning) since 1978, except for laying them asside on the hoses for repacking bearings and one time turning the rotors. I still had original hoses and hadn't ever disconnected them before this morning.

Hope we helped

Early build SJ 67 car's used the small inlet like the 65/66 and the later production cars used the larger inlet. Just one of the many running changes in 67.

Do these part numbers and stampings look correct for a Dec 66 SJ?  If not what should I be looking for?

An original example from a December 15th scheduled car - Looks like a possible match





And just for comparison for others, one from a March scheduled example. Both San Jose

Hey that is often my line - no fair!  Thanks for the replies, will check thread sizes also.

[67gta289]

Thread size on the source line is 7/16 x 24 NS (national special).

Jeff, not to get off trail, but the first picture you provided has what I normally consider a 65-66 brake pad retainer (one large piece), whereas the last picture has what I consider the 67 style, two independent smaller retainers.  Do you concur, is that a slam dunk observation, or do I need to start a different thread?  I guess my post started with threads and ended the same.

Thanks, John

Jeff, not to get off trail,..................

We're still discussing Early San Jose calipers no problem following this path of discussion

Believe you will find that the details you see in that picture is the way early 67 San Jose Disc brake cars were equipped and that the retainer changed with the change to the "stronger" reinforced caliper later in the year.  Looks like the original safety wire is still in place a rare occurrence IMHO

[67gtasanjose]

John, Jeff's first picture and all of the pictures in your original post seem to follow your questioning for EARLY caliper design. and all of those pictures look like what I have on my very early November SJ example. (pictures of my calipers are in the other thread I put a link to earlier)

I couldn't tell you when the 67 late design entered the picture (fairly sure the MPC would give the date) but it MAY stand to reason the change occured whenever all of the brake/fuel lines design changed

I have the MPC now on disc but it is at work, so  cannot look at this moment It stands to reason, like Jeff said, that  the hardware would change at the same time the calipers did.

I'm getting too OLD to "keep up" with all of the "RUNNING" changes of the 67's 

John, I brought this old topic up to help tie it in to the other newer thread

Checked and the MPC shows a change from C7OZ-2B120 & 2B121-B to C7OZ-2B120 & 2B121-C on 10/17/66 but that doesn't seem to hold up well when compared to what they actually did at the plants - original unrestored examples. Another swing and miss for the MPC

BTW the page is from a Aug 1967 version

Here are some shots of the calipers that were on my 1967 390 GTA convertible. The car was built in SJ on Sept. 22, 1966. 
The first five photos are of the driver side caliper, and the other seven are the passenger side...

Those are the later style with the different bolts and the larger diameter C7 brake hose.
