Why did you use the 68 instead of the 67 the 4 piston setup is better.

I used the 68 setup for easier setup and maintenance. The single piston setup has worked well enough on my trucks for daily driving and towing. It will be just fine on the 67.
Yes there may be some performance trade-off vs. the 4 piston setup but this is not a race car.

~$500.00 for 1 pair of proto-type adapter brackets, --which includes converting my drawing to a CAD format that could be programmed into the CNC milling machine, material costs, setup and labor time. Essentially $65.00 per hour.

After the intial proto-type is made, the cost is not as much per pair, but for a producton run of them, I will have to come up with $3,000.00 to have them produced.

Producing conversion parts is both very time consuming and very expensive as well. I'm just a regular working-class dog like the rest of you. Producing Mustang brake conversion parts is just something I do on the side, so coming up with this kind of money is a major expenditure for me.

Thanks for developing these parts!!

I got my adapter plates from Ultrastang, excellent pieces

Thanks for you moral support. I was born to Mustang, but I'm forced instead to work for a living.

I think there's a stigma by many that think an individual can't come up with quality, professional grade/looking, conversion components. They have this idea if it doesn't say "Baer" or "Wilwood" etc., that it's something of poor quality and is no good. In reality, there are private individuals who produce components that are just as good (or in some cases better) as the name-brand stuff, but the biggest difference is in the price tags.

I may not be Baer or Wilwood, but the brake conversion adapter components I produce are quality components that were produced on CNC-controlled machinery by professional machine shops, so they definitely aren't sloppy pieces of junk.

--Evidently, I'm doing something right, since another "producer" of conversion components has "barrowed" information from me to produce/promote their own products. ...and that's all I've got to say about that.

Don't take it personally. Existing companies tend to troll for new products. Little guys like you and me succeeding in the marketplace affects the sales of their existing related products. Keep in mind that neither you or I came up with the idea of using Granada based parts on Mustang or even performance calipers or brackets on Granada spindles.

This is probably so, but I wasn't actually talking about the front disc conversion I've been working on. I was actually talking about the rears. A competitor bought an SN-95 bracket set from me, then afterwards, began offering components/information to promote their own products from some of the information that was gathered from my SN-95 setup.

Okay I'm definitely subscribing to this thread.

On the master cylinder subject you guys were discussing earlier, will the late model Cobra MC bolt properly to a vintage style power booster?

LMan · Nov 14, 2006

It will bolt up, but you need to check clearance to the shock tower, and you may need an adjustable brake pedal rod.

www.ultrastang.com has a page with several MC/booster combinations already doped out.

it also depends on which Cobra master we're talking about. IIRC the hydroboost mc has an oddball mounting flange.

Steve, i noticed that shortly after you came up with your sn-95 rear disc brackets that another person with the initials MS came out with some as well. is the someone we're talking about? actually i noticed a couple other companies that started making them shortly afterwards as well. RR and Currie both started making similar ones but the MS one seemed to have been the closest to your's.

That is correct. The '94/'95 Cobra MCs have the correct horizonal mounting flange pattern to be used with a vacuum booster.

Starting in '96, Ford began using the Hydroboost systems in the Mustangs that have an offset vertical MC mounting flange pattern, like this:

These are some of the photos I have on various MCs/boosters;

'87-'93 5.0L Fox Mustang brake booster in a '68 Mustang with a '94/'95 V6 Mustang 4-wheel disc MC (minus the reservoir) --essentially the same MC as the '94/'95 Cobra, but with a larger piston bore than the Cobra; http://img175.imageshack.us/img175/166/foxboostermkviisn95mc00ud1.jpg

'87-'93 5.0L Fox Mustang brake booster in a '68 Mustang with an '84-'90 Lincoln Mk VII 4-wheel disc MC --Left front edge of MC's "snout" had to be radiused to clear shock tower. It's close, but it does clear; http://img228.imageshack.us/img228/7480/foxboostermkviisn95mc00up0.jpg

Thanks for all the pics...you're saving us tons of trial and error work. I think I've been to all the corners of your site, but I don't quite get what the advantage to running the late model booster is when we've established that the late model MC will mount on the early booster. More compact? Better assist, maybe?

At least in the '67-'70 models, you could get the stock early type booster/brake pedal to install in them. However, back in '02, I had a '90 Mustang GT parts car that I had pulled the fuel-injected 5.0L engine, T5, etc. out of. My '68 had manual brakes and I wanted to see if I could make the Fox brake booster work in my '68. The early Mustang factory Midland/Ross boosters are noted for experiencing problems. The Fox boosters on the otherhand, have a low failure rate, are relatively cheap, and are very abundant and easy to get.

On a '65/'66 Mustang, the stock '65/'66 Mustang power brake booster takes up too much space between the firewall to the back of the shock tower, because of the way the mounting bracket pushes it away from the firewall. With that booster, you can't use a dual reservoir MC. So, a good way to get a power brake booster that's compatible with a dual reservoir MC, is to use a Fox brake booster.
