Would changing the master cylinder on my 68 to a fox style one ba a bolt on type deal or is there some fab work? What are the benifits of this type of swap? It has manual disk brakes the the master cylinder off of a 72 stang on it now.

Yes, it will bolt right up. The lines are on the opposite side of the M/C so you would have to fab up some new ones to the junction block. I have one on my '67, being aluminum it is lighter. I sanded mine smooth, polished it and put a chrome lid on it to detail the engine compartment.

The (disc front/drums rear) Fox MC has ISO metric bubble flare fittings, and not the common SAE inverted flare fittings you'll find elsewhere on your '68. You will have to adapt or find the correct fittings to go from the newer Fox MC to the older brake line plumbing of your Mustang.

If one had a pipe flaring tool kit, could this be overcome by making your own lines?
Then one end could have the metric connection and the other standard.
Am I thinking right, or does the metric version have to be made by some other means than a typical line bending/flaring kit?
Thanks
Dave

Hi Dave,

You are correct that you can use metric fittings on one end, and SAE inverted flare fittings on the other end of the same piece of brake tubing.

Metric 4.75mm tubing is the equivalent of 3/16" SAE, so as far as that goes, either ISO metric or SAE inverted flares can be used on 3/16" tubing.

ISO bubble flares require a special flaring tool, just as SAE inverted double flares require special flaring tools. However, one flaring tool cannot make the flares for the other system.

In addition to SAE inverted flaring tools, this is the ISO bubble flaring tool I have; http://img76.imageshack.us/img76/3046/bubbleflaretools002ro7.jpg

I have a standard flare kit, but I also have a kit with the same type of ends that are in the upper right portion of your box here... There are about 10 different ones in my kit. I have no idea what they are for.
My old man gave me both kits, but I only have ever used the flare kit.

IF they are double flare buttons, they are not like the buttons used with the bubble flare tools. --They won't make the correct flares on the ends of the tubing for metric fittings, if that is what they are.

Cobra Automotive sells a master cylinder "kit" with adapter lines and either factory-style distribution block or proportioning valve. Their website has a pretty good picture of it, go take a look.

The booster is a 67 rebuilt unit from NAPA.......

I then spray painted it using the cadmium kit from Eastwood.

To me, it is to deal with swaps from drums to discs.
Especially if you use Crown Vic or Exploder rear discs out back.
Or even just putting discs up front.
You can mix match masters, but the closer you can get to matching what you have to a master made for that combo, the better off your brakes will work.

Now others might have different reasons for swapping up masters...
