What would correct finish for master cylinder be? 66 GT Mustang disc brakes built in San Jose. I've seen most cast iron color with the plated cover. Then again I've heard masters were painted black along with the covers...
-
Painted all (body, cap and retaining clips) semi-gloss black before it was installed (painted by the supplier)

I've just received my December 2013 issue of Mustang Monthly (M/M) and there is a article titled Identify Dual-Chamber Master Cylinder Caps. The article deals with concours detailing for 1967-1973 M/C caps. In the article the author (Marcus Anghel) states that " in 1966 Ford decided to start referencing its own brake fluid part number (C6AZ-19542-A) on M/C caps due to concerns about the higher temperatures created by front disc brakes" I sent a e-mail to the author asking if he knew when in 1966 did Ford start doing this. It sounds like he has done some research and I'm hoping to hear back from him.

Date listed in the TSB's was March 26th but the text does not specifically state Mustang though one would believe that it was an across the board change not just one car line. The challenge so far is finding late cars with a decal to support the text
Subject has been discussed here and on other sites a few times -

In the article the author said that the decal was used on Fords with disc brakes. I've been around Fords and do remember seeing the decals on the old cars. The reason given by the author for Ford doing this makes a lot of sense. The author states that the 1966 part number carried over into early 1967 Fords with the dual chamber M/C disc brake cars utilizing a different shape sticker than was used on the 1966 single chamber M/C.

That's correct. As Charles mentioned Marus posted the basic article here for review before it was submitted
-
I must have missed the earlier posting.
-
Richard I must have missed your email, but now see your posting here. I try to keep up with the forums when I have extra time.
To answer your question, I don't have an exact date when the C6 fluid was introduced only that general time. What Jeff added here about the TSB would be a good reference but cant say exactly when things were done.
-
Thanks for your reply Marcus. I sent the e-mail through M/M so maybe you haven't received it. I enjoyed reading your article. It makes a lot of sense.
-
Ok, that's why. Probably easiest to contact me thru these forums or thru my website directly.
Glad the article made sense. Working on several more right now.
-
Second question...does the decal that was on the cover go on after paint? I'm assuming yes but wanted to check to make sure.
-
Yes, paint first then the sticker was put on. Plus its easier that way....
-
+ 1 Paint First

+ 1 Paint First
Difficult to read the important message on the decal the other way around ;)
As far as the TSB article change dates I've found them allot more reliable than say the Assembly Manual dates since normally they were reporting what happened rather than what was suppose to happen. Problem with this subject is that we don't know when our 65-66 cars were built like later years :0
-
Just curious if the sticker was on or not. Never intended to put it on first then paint. ;) Thanks though...

So I've read several threads on this site about the master cylinder and lid getting painted semi gloss black. I'm about to paint mine and my question specifically is regarding the inlet area. Was there only a plug inserted and then the whole thing was painted or was the area I've shown in blue in the attached photo left unpainted? A lot of pictures I've seen here looks like that entire area is left unpainted. If it was unpainted, was it left alone or was that sort of a machined surface?
Also, what about the other area where I have the arrow pointing to, was that area different or the same as the inlet area?
Thanks,
Jason

As we understand it and how they have been found shipping plugs were placed in each threaded hole and then the unit was painted leaving a shadow just around the fitting area not like it had been painted and the whole machined surface was left bare

Thank you Jeff for the final clarification, it’s painted now and ready to go.

The plug was about the size of a dime. It was not the size of the entire flat surface as highlighted in the picture. Only the area under the plug would be unpainted .The unpainted circle left after the plug was taken out would be about the size of a dime.

Apparantly I am not using correct terms, tried quite a few search descriptions, what is correct m/c finish and cap finish on 66 k code, gt, SAN JOSE 11/08/65. May have found it, semi gloss black for body and lid?

Yes,semi gloss black for body and lid.

Bob does that include the 2 clasps that hold the lid in place as well?

Painted as a unit so yes. There were two small round shadows produced by plugs installed at the time it was painted so once installed you will see a small radius of unpainted bare steel around each fitting but not all the way to the outer edge of the machined surface
