Looking for a Dual Master Cylinder for a 65.

spirockp · Aug 28, 2006

Does anyone know if this exists?

A Dual Master Cylinder for a 65 Mustang. All drums all around and manual, NO power. I've called a few placed and they say they don't have any?

I know the right thing to do is to upgrade to Discs up front, but as of right now were trying to just make it a bit safer.

Thanks.

The 65 didn't come with a dual reservoir MC. I think read that a 74 Maverick was easy to plumb for the early Mustangs.

The 641/2 and early 65s had single bowl MCs but I think they had duals in late 65 or early 66. Icould be wrong though. Try asking for a 66 MC. Also I believe that early 70s Maverick MCs will bolt right up and are easier to get. either way you will have to do some plumbling to switch from single to dual.

In my search they said 65 or 66 I couldn't get anyting. Now where do I find an early Maverick dual MC?

OK here is the part suggested.

Why does it make a difference if there are discs up front or drums. I don't understand.

Thanks.

They have different size bores and residual valves.

The 66' Mustang still has a single bowl mc so it is not an upgrade.

I've done the swap to dual MC many times.

For a car with 4 wheel drums you should specify a master cylinder for a 1967 Mustang with manual drums which is perfect for your application, although one for an early Maverick would work too. Any autoparts store can order you one in. Buy a new one, not a rebuilt part as the tolerances may be too great on a previously used part.

You should retain and use the pushrod found on you current 65' MC as the 67' will be of a different length.

Be prepared to do some line rerouting to install the dual MC. You will need to separate your single output line into 2 separate ones so that one powers the front brakes and the other powers the rear. Benders and a double flaring tool may be needed. Special fittings are needed to attach the lines to the new MC. A good autoparts store (like NAPA) should have them.

Dennis, thanks for the info. My Father's Mustang thanks you.

Vinyl66 · Aug 28, 2006

Exactly what Dennis said.

That is very smart of you to get rid of the single master cylinder. They are very dangerous. Ask me how I know.

I swapped mine(66 Mustang 4 wheel drum no power assist) to a 1967 Mustang dual master cylinder from Autozone. Very cheap and it has been working great for the last few years. I even bent the lines by hand. Just be careful not to crimp them.

stangkid88 · Aug 29, 2006

Exactly what the two above me said, use a dual master cylinder from a '67 stang. This is what most brake kits from the big companies come with, and I've been looking to do the same thing as you soon.

spirockp · Aug 29, 2006

Funny that the some of the big Mustang places I called said they didn't have anything.

Again this forum rocks!

This kit makes it real easy

as was stated, the 67 mustang master cylinder for 4 wheel drum brakes works fine. if you upgrade to non power disc brakes, then get a master cylinder from a 75 granada with non power brakes as it is a straight bolt in replacement for the fruit jar m/c, including the push rod length, except for the line routing.

D Durden · Aug 31, 2006

Now, the big question . . . what about 4 wheel disc brakes? Anyone know a trick power setup for a 65?

perhaps a master cylinder from an 85 svo mustang?

D Durden · Aug 31, 2006

Hmmm . . . that's the first I've heard of that. A standard '85 GT one won't fit, I don't think.

I'm going through this right now. Yes, the 1984-86 SVO is what you use. The ports are on the right side but it will still work. You can't use a booster that converts from manual pedal to power because the booster's bracket is so large that the MC will not clear the shock tower or the export brace. The only solution is to use MustangSteve's Setup. Also, if you have an original manual tranny, it will not work. If you have a t5 it will work if you convert to MustagSteve cable clutch setup

D Durden · Aug 31, 2006

Yeah, that's all I've heard works, too for power and a stick.

rbohm · Sep 1, 2006

the nice thing about ford master cylinders is that from the late 50's to the current day, ford used the same bolt pattern so all master cylinders will physically bolt in place of each other. the push rods, and push rod cups are another story though. push rods however can be interchanged, or you can get adjustable push rods now.

Shakin66 · Sep 1, 2006

Hey if it helps you I have an 84 SVO master cylinder that I have scheduled to run on ebay starting this Sunday. If you want it for $35.00 I will take it off.
Let me know
Its brand new and the link to the auction is here:

You should be able to cut & paste that to your address bar.

Not the only solution...

There are booster/master combos available for the 65-66 cars with manual or automatic set-ups... They reposition the booster with a bellcrank type of arm and it clears the clutch rod.
