SN95 to Classic brakes

65mistress · May 18, 2005

Hey all

Do any of you know if the thread for the guys engineering the brackets, to put the SN95 Cobra front brake setup onto a 65-67 mustang using the stock drum spindles, survived the server crash or whether or not that went any where?

Thanks

sweet i want some

The thread should have survived, it was started well over a year ago. There have been about 6 people who claimed to have made their own brackets, a couple who were selling them but whenever someone tried to buy them or get pictures they sorta just vaporized. Engineering and manufacturing adapter brackets is out of my comfort zone. But it should not be THAT hard for someone with the approriate background and expertise. One of the biggest problems is going to be WHICH factory spindle to use, there were three different factory spindles just in the 1967 model year. One of the best things I heard was to use 70-73 (I don't know why 69 was not included) drum brake spindles since they are the strongest ones. But whomever makes these adapters will most likely pick whatever they have on hand. Mustang Steve has been around for quite some time, I hope he follows through with this!

I have in my possesion:

one set of 13-inch SN95 Cobra rotors
one set of SN95 Cobra Calipers (PBR)
one set of 67 PDB spindles
one set of 71 Mustang drum brake spindles

Needless to say I hope this happens!

Edbert, will the rotors fit on either spindle?

Edbert · May 19, 2005

My understanding (YMMV) is that the adpters will HAVE to be spindle-specific.

Edbert · May 19, 2005

Looking more closely at the pictures I am now wondering what kind of bearing arrangement he plans on using. It looks to me that the beefy part toward the inboard side will be obstructed by the thick adapter.

Edit: this isn't quite what you wanted, but it's a way to get modern brakes onto your classic. These are the only actual drawings I've seen on the forum.

Do a search for PBR calipers and you should find it. The only brackets that I've seen drawings for are brackets that allow the '99-04 GT and V6 front calipers to be used with Granada spindles.

There's the thread for doing that. I like the idea of an adapter for '70 drum brake spindles as well, but those brackets are a lot more complicated. I think the PBR calipers could be mounted on Granada spindles by anyone with a welder and just a few hand tools. I plan to do the PBR calipers on my '70, which has the Granada brakes right now.

Edit, one other thing. I don't really like the idea of mounting the caliper to those holes that are sized to hold the backing plate in place. Yeah, there are four holes, but they aren't sized at all properly. Compare them to the size of the holes in the caliper itself. Now consider that the caliper has a longer lever arm, so the force is multiplied at the location closer to the spindle. They are also coarse thread. I suppose the spindle could be drilled and tapped for something about twice the size, and that could do a great job of keeping the caliper from tearing itself loose. I wouldn't publish a drawing of a bracket that used those holes as is, even with disclaimers.

This is the link I have from ages ago, I also saved it on my drive "just in case". Good to know the site is still up, though. Useful to anyone?

i don't see a problem, ford thought it was good enough for their own disc brakes on 65-67 cars and later they used the same type of setup on the 70 T/A boss cars with bigger calipers and rotors. i plan on doing something similar one of these days, but mine will be made of steel and fabricated

1320stang · May 19, 2005

But what I'm asking is, do... the... rotors... fit... either... spindle....? I didn't ask about if there is a universal bracket, and what the heck does YMMV mean?

I can make brackets for the damn spindles all day long, but if the rotor won't work on the spindle, it's not going to do any good.

Having not read about using these rotors on old spindles, and whether or not you have to change bearings and such, I have no idea if the spindles will physically work on said spindles.

I'm trying to help you out here..... (must be a longhorn fan LOL!!)

Ford mounted a modern PBR caliper to 65-67 drum brake spindles?

I learn something new every day!

67efivert · May 19, 2005

im in the process of installing pbr calipers and rotors off of a 2000 gt car on my stock 67 spindles i had to turn down the original drum hub a little to fit in the rotor but so far no real problems other than that i am making a small spacer to go behind the rotor that will also serve as a centering device for the rotor since the centers on the old hubs are smaller than the rotors.
good luck to whatever u try

ddonaca351 · May 19, 2005

LOL...

Well, I am still making mine, but I am making them to fit the 70 disc brake spindle (cuz thats what I have).

In answer to your question what you need to do is make a hub that has internal dimentions to fit your spindle, and external dimensions to bolt to the 94+ cobra rotor. (they are a two piece design where ours were all one piece)

Another side benefit to this, is you can modify the hub design to change your backspacing to better fit aftermarket wheels... (within reason, the wheel well is only so big.)

Hope this helps,
Dave-
