Topic: 67 Disc Brake Caliper Assembly and Rebuilding

[BKnapp]

I finally finished cleaning, plating, and phosphating my caliper parts and have a few questions about putting it all back together...correctly. The car had been previously "restored" and the brakes were a mess. With the help off Jim's amazing spreadsheet, Jeff's pictures, the MPC, and the Shop Manual, I still have some questions:

1) Caliper mounting safety bolt - do these use lock washers? Mine had them, but I don't see one in the MPC illust.

2) Caliper assembly bolt - mine had one and this does appear to be correct. Interestingly, a remfg caliper I just recieved does not have the lock washer.

3) Crossover (transfer between inboard and outboard) brake line - I believe there should be copper washers, but mine did not have them.

4) 7/16 inlet line - I believe this should have a copper washer, mine did not.

Any insight and help is certainly appreciated!

Lock washers on both Caliper mounting safety bolts as well as the bolts holding the 2 halves together.
Crossover line has no washers - they are flared tube fittings with tube seats.
Inlet brake hose line has flat copper washer.

Thanks! So pretty much as I thought it should be and still have no idea why they included (2) 3/8" copper washers with the rebuilt caliper I bought. My first attempt at doing "anything"'on a car. I have never media blasted, played, phosphates, etc...It's not perfect, but the learning process and experimenting is fun.

Bill, the front half of the caliper was ether plated silver or painted silver . I have seen it both ways . This was a practice started in late 65 production so that flash rust on the casting would not be seen through the spoke of a deluxe wheel.

Bill...looks really good.  Doing your own work can be rewarding...frustrating at times...but rewarding.

Bob,
Attached is a picture of the left front caliper from my 67 April Metuchen FB.  I was under the impression the "silver" was originally black-out paint (my car came with styled steels) - simply faded and washed-out.  However, after reading your post above, the silver was probably silver, not black as I had originally thought.  Would this be consistent with my cars plant/month?

Thanks,
Mark

Note: ignore the red paint on the dust cap...PO painted many things red (differential, 12" long rear shackles, radiator support).....I guess in the 70's red made it go faster!

Thanks for the input, Bob. I will probably give it another try this weekend. When looking at Marks picture (and others on a different thread), it looks like the plating only covered the outside face, not the whole outboard caliper. Is that correct base on your observations?

Thanks!

It started out in 65 as only cars with deluxe wheels from Ford got the silver out half calipers. Steel wheel cars were all cast iron. I guess ford thought it more practical to make them all the silver outer half way. As I wrote previously the silver on the outer half of the caliper evolved to being done as a production standard sometime in later 65 production . It continued through 66 and 67 production. The caliper is made up of two halves. The front halve(facing to the outside ) was typically plated or painted completely all over but just the outer half. If painting with the no smudge aluminum paints (Aluma blast etc.) are a very close approximation to what ever the factory used. The practice of "blacking " out the front calipers was for later years and a subject for another thread.

Realize (as we always remind each other) that service replacement parts don't always reflect the finishes, design or style of the factory installed part since on of these examples is a NOS piece but it does appear in this case the NOS part does match the factory finish

So to illustrate what is being discussed here are a few pictures

[BKnapp]

Well, this is as close as I think I can get it for now. I want to get things back together so I can drive it and see what else might need attention. This winter I will likely tear into it again and start with the master cylinder.

Thanks for all the info and pictures!

Knee deep in this right now. Question concerning finish of each item. My guess is after the dash. Please note that this is for late 67 (after Nov/Dec 66).

1. Caliper half bolt -- PO
2. Caliper half bolt lock washer -- Cad with knurled outside
3. Caliper bleeder -- gold dichromate
4. Pad hold down --  PO
5. Pad hold down bolt with captive star washer -- zinc or PO according to NPD
6. Crossover tube --  Terene (not stainless)
7. Crossover fittings on tube-- natural

Blue is revised

For extra credit, what color is the backing plate on the Shelby brake pad? Gold Dichromate?
Pad color? Light blond?

[Bossbill]

Updated my synopsis with Cad for caliper half bolt lock washer (per Jeffs last pic) and PO for pad anti-rattle/hold-down.

[Bossbill]

In keeping with the spirit of this thread which is leaning toward assy line finishes on all parts, is the Kelsey-Hayes dust boot the correct one?

Jeff's pic appears to show a black brake pad and a metallic  friction pad.
Might be for a standard DB setup. The Shelby pad, in which I'm interested, is still unknown in its color.

In the process of rebuilding the front 4 piston kelsey hayes calipers. I've tried searching but couldn't find what I was looking for.
I have a couple questions on the finishes of some of the fasteners and parts.
What is the correct finishes for the following:
-2 bolts that attach the 2 caliper halves together
-2 lock washers for the caliper halves bolts
-Pad retaining clips
-bolts for retaining clips

There's a bunch of them.

Do note that I address a lot of finishes on the post Dec. calipers.

Thank you for the link! I knew I’ve seen one before but couldn’t find it again.
