Cobra Brake Setup

[SuperSnake428]

I know, its a dead horse.. its been said a million times and I appologize in advance. I've read all the posts that I can about this. But being a poor, starving college student just trying to build a quality muscle car in my spare time, I have to double and triple check parts before I go spending money!

Presently I have disc brakes (11" maybe, not sure) on the front and drums on the rear. I would like to upgrade the brakes to the Cobra setup. Since I plan on running 17" rims all around, I won't have any issues fitting the larger disc brakes.

I was planning on purchasing a kit similiar to this http://www.blueovalindustries.com/products.php?pid=636&openparent=1287&dealer=blueoval
that include cobra slotted and cross drilled 13" rotors and calipers for the front as well as 11.65" slotted and cross-drilled rotors and calipers for the rear.

In order to make these fit on a 67, I see that I need to purchase Mustang Steve's front bracket and Ultrastang's rear bracket.

My concerns are, since I don't have front drum brakes currently, I will have to go hunt down some front drum brake hubs right?

How does the parking brake setup work with ultrastang's rear brackets and the cobra calipers?

Is there anything that I am missing/not understanding before I go spend my lunch money on car parts?

Thanks! (and I appologize again for YET ANOTHER brake question)

Im not sure about the whole parking brake setup, but yes you do need the bracket form mustang steve as well as the drum hubs. Though i think you should also look at the cobra brake setup on mustang tuning: http://mustangtuning.com/ford-racing-cobra-brake-conversion.html and then just look into a granada disc brake setup in the rear and you will be totally fine, and it will save you money, which is undeniably a good thing :

The only thing I don't like about that kit is the rotors. I'm looking for slotted and cross drilled rotors. I found a cobra kit that has all 4 rotors this way.

Also, I guess that I just don't know much about the Granada swap, but I don't want to affect track width anywhere. This will save me from having to get custom backset wheels.

one thing that you must kee in mind is that if you are buying a cheap brake setup where the rotors are slotted and drilled there is a chance that you can crack the rotors and then you will be unstoppable, literally
and a granada swap is probably easier to do than a cobra swap.

In regards to the SN-95 V6-GT/Cobra rear disc conversions, the stock SN-95 parking brake cable can be spliced into the existing portion of the brake cable system. Alternatively, you could use a custom parking brake cable from Lokar for these rear discs setups as well.

I didn't see if you mentioned what year model your Mustang is. Granada disc brakes will work on the '65/'66 models as long as you pretty much leave the front suspension alone (i.e. don't drop the upper A-arms and use lowering springs). If these things are done, then you run into Ackerman problems that can induce unwanted bumpsteer problems.

If you have a '67-70 Mustang though, installing the '75-80 Granada/Mercury Monarch / '74-'77 Maverick/Comet disc brake spindles is not a problem, since they share the very same front suspension geometry layout as the '67-'70 Mustangs. Lowering the A-arms or using lowering springs doesn't cause any problems with bumpsteer when adapting the Granada spindles to the '67-'70 models.

The '75-'80 Granada 9-inch rears with disc brakes (exact same thing as the '77-'80 Versailles disc brake rear ends), are very expensive when it comes time to replace parts (particularly the calipers). Ford has long-since stopped supplying replacement parts for these rear ends. I had a '79 Versailles rear end under my '68 that I replaced recently with an '80 Monarch 9-inch drum brake rear end. I converted the Monarch rear end to Cobra rear discs which helped shed some unsprung weight, but the best part is the discs/calipers are new, late model, components that are readily available from Ford, the parts stores or from the aftermarket.

The newest componets I got today are the slotted/cross-drilled 13" Cobra rotors. Brembo is the OEM supplier to Ford for the Cobra rotors. The rotors I bought are made by Amico. They are a heavier-duty casting with a thicker webbing between the friction surfaces that gives these rotors more strength over the Brembos --particularly if the rotors have been cross-drilled.

I plan to adapt these 13" rotors and Bullitt calipers (same PBR calipers as the Cobra/Mach 1) to my Granada spindles on my '68 notchback.

--incidently, "G2C" stands for;
"Granada-to-Cobra" conversion.

You will also need to get a master cylinder that will work with that swap and the fluid needs of the new calipers.

What hub/bearings are you using for the G2C swap?

I'm using the hubs from a '70 Mustang disc brake assembly. The '70 Mustang drum & disc brake spindles have the same size spindle pin and bearings as the Granadas.
