Title: '67 Shelby brake drums
Post by: 1967gt350 on November 13, 2012, 04:19:57 PM
     Hi

     Sorry if it's already been addressed, but I couldn't find it posted elsewhere on this forum. Just curious for a Nov./Dec. '66 built GT350 with Magstar wheels do I blackout the face of the rear KH brake drums? If so, what would be the correct process?

     Thanks...Mark

Hi Mark,
To keep it simple-YES the face of the brake drum belongs blacked out.This applies to Ford cars in general with special wheels.
The most common method was to brush on the paint with a fairly wide paintbrush....on the face of the drum.This is for cosmetics only.
I think they did not paint the entire drum for 1 simple reason:Heat from the brake shoes would cause it to blister off.
There was a few pictures in Mustang Monthly showing a rear axle restored by Bob Perkins,that demonstrated this really well.
Hope this helps.

That's odd. This morning links were broken but just opened them to relink and they were back. Odd - Maybe the newest version of Foxfire did something. Relinked them again anyway to pictures stored here on or site

Thanks Jeff!
So, just slathered on after the drum nuts, eh? Kinda sloppy, yes?

Yes and not kinda sloppy - just sloppy :) Likely a 4 inch brush dipped in a coffee can of black paint sitting at that station.

My wife is already looking at me like I'm mad taking my nice pretty, primered car and glopping stuff on -- like an assembly line worker.
But this should cause a few eyes to roll.
Thanks!

Not just a Shelby thing...a Styled Steel wheel Mustang thing too! Gee, I just spent the day cleaning up my original drums, rust removal, machining the two notches and other visible surfaces, added back the heat treatment to the balance weight and all of that work just to slop on like a 5-year old did it? Hmmm....lol!

A friend of mine sent me a pic of his Shelby brake drum and asked if mine were the same.
Well, no. His said 'Century'. Mine said 'KH'. I've seen Century rotors mentioned here -- but not drums.
After looking at Jeff's pic and comparing it mine it appears the visual clue to the 2 1/2 KH drums are the two square holes.
I've never noticed that until now.

Since I'm trying to use up some media contaminated with brake residue (yes, my system vents outside) I figure I'll just do the drums and rotor hubs now.
However, it doesn't appear my assembly line drums were ever lathed on the outside "band" like other drums.

Typical outside "band" on these and an overall shot to show the square holes.
Black paint still visible!

I have found that many were not lathed . Maybe a different MFG.

Thanks, Bob. I know these rust, but surely not enough to obliterate all the shiny bits.

Now to go read some more threads on restoring these. It's really interesting that the car still had the stock drums fitted!

This appears to be the de facto brake drum thread even if the original topic started with the black brushing.

Here is a better pic of mine, with the front steel face in its final color (?) but the outside is currently cold phosphated to keep rust at bay. These thing rust immediately after media blasting. I'll probably paint the outside with Eastwood gray manifold hi-temp.

This pic shows the FoMoCo stamp, another number, as well as the square cutouts in the face.
That's a big weight!
The drum also has a single bead in it.

Just posted a pic in my build thread of the Eastwood gray exhaust manifold high temp paint on my brake drum. Here is a linked image:

How about if I throw in the 2 1/2" rear brake shoes into this Shelby discussion?

I was looking at Charles' post about his earlier brake shoes and the pic he shared on the FB forum and see that he has silver colored brake shoes (the shoe, not the lining). Of course, different year and all that.
I don't know why, but I never looked at the shoes on mine and found these marks on the primary and secondary shoes.

I don't know if this K/H part number decodes as an original piece (48118).
I also don't know if the bronze metallic is the right color.

If you are referring to brake shoes on the 65 GT350 Charles has been working on then they are completely different from the 67 ones in your picture. 65 /66 GT350 was semi metallic material and were segmented for cooling  (a truck part ).The soe material has a gray with silver metallic particles imbedded in the material for a distinct look compared to regular brake shoe material like in your picture. Also they were bonded and not riveted to the shoe core. 67 Shelby shoes changed from the semi metallic which required more foot pressure when cold to the typical material used on regular production Mustangs and full size cars.They were also not segmented like the 65/66 GT350 . I believe the assemblyline 67 2 1/2 shoes were also bonded with no rivets.

I don't have any samples, do the bonded lining versions have holes for where rivets could be placed in other applications? I seem to recall seeing goop coming out these holes on other applications.

Holes in the metal core but no holes through the lining material typically.
