Default 1962 T-bird single to dual master cylinder

I'm new to this site. This has probably been talked about before. The brake master cylinder on my '62 T-bird locked up and I had a 4 wheel brake meltdown. I havn't checked the drums yet. Right now I'm just getting information.

As long as I have to replace the single stage master cylinder, I would like to convert it to a dual stage. What year Ford master cylinder should I use. Will any '67 Ford with power brakes and 4 drums work. What model Ford, and year master cylinder should I use? What about the push rod lehgth?

Thanks for any help.
Lyle

I have a '60 but changed to front discs years ago -- it is a disc/drum system though.

While I was doing my conversion I was told the late 60's Mustang master cyl is a dual mater cyl and will work for a drum/drum system. Might work for your application on a '62.

Not sure what length push rod.

A fellow who might be able to help and did the conversion on my booster is Booster Dewy @ Power Brake Booster Exchange. He will most likely know what length push rod. He's always been very helpful when I've called.

There is a super long discussion on the 58-60 forum about disc's and dual master cyl - might get some info there if you have a few days to read it.

Good luck.

Hi Eric,

Thanks for the help. I will contact Dewy. I'm sure glad I found this site.

Lyle - hope Booster Dewy was able to help you out - surprised no other Bullet Birders jumped in to help....! ? Oh well - guess the Bullet Birds are not converted as much as the Squarebirds. Post your results with a pic or two if you have time. I'll send a PM to another member who helped convert other cars - maybe he can give more info as well.

Eric

Eric, I think a '67 Galaxie with drums all around and power boost should work.

Lyle, we need a little more info... will you be going to Power Brakes?
If so, the M/C bore needs to be larger (1" min.).

Are you considering Disk Brakes? <--This is where you gain the biggest advantage, but the system needs different components and different plumbing. If you want brakes that put you through the windshield (like a modern car) this is the way to go. Disk brakes require a lot more pressure to operate than drum brakes. So, get a booster large enough to accommodate your new calipers (at least 800-lb boost). - Dave

Dave, I'm just changeing the master cylinder to a dual system for safty with the original Ford drums and power booster. I know disks are better but I've been told by the companys that sell the kits that I would need to change the wheels from 14" to 15" which means new tires too. My T-bird is just a driver to a car show once in a while.

Eric, Thanks for the help.

Lyle, I'm only asking because I would hate to see you do this job more than once.

Keeping your drums is ok and I applaud you for putting your family's safety first.

You will need two things:
• A dual master cylinder with 1" bore (yes, the Mustang cylinder works very well).
• A drum/drum combination proportioning valve.

The proportioning valve serves two important functions. It meters (so the rear brakes come in first), and it shuts off a leaky circuit (so you don't run out of brake fluid if a hose breaks).

Many Ford cars with disk brakes came with 14" wheels. Switching to 15" is an easy solution, but it isn't absolutely necessary. "Disk-ready" 14" rims are available. - Dave

Should you decide to go the disc/drum route, with disc brakes up front and drums in the rear, you will need to find some 14" disc brake ready rims. Here is a list of Ford cars with disc/drum brakes whose rims should work on your Bulletbird. Some of us who own Squarebirds with 14" rims have satisfactorily converted our front brakes to disc using these rims, and also parts that will work on 14" rims. For much the same reason you have, we did not want to buy new 15" rims and tires, especially if the tires are new like mine are. Should you decide to go disc/drum, there is a ton of information in the Squarebirds Forum about this, much which should be usable on your Bulletbird. It is NOT necessary to buy 15" rims and tires to do this conversion. It IS necessary to get the right 14" disc brake ready rims though.

WHEELS/RIMS

14" rim Info – Original OEM 14" rims will NOT work. 14"x6" and maybe 14"x7" rims with a bolt pattern of 5x4.5 and lug nuts 1/2-20 are what you are looking for. I am told that offset backspacing and rear spacing are not a factor if you find the following rims. 70's LTD II. 14" Ford wheels with the numbers 43M below the Ford script, a 22 on another lobe of the center and a 3 next to the valve stem. Make sure they are vented rims. They have to be rims made for a front disk brake/rear drums car. Any 1977-1979 Lincoln, Versailles, Granada, LTD II, Torino, Ranchero should work. A 1998 Ford Ranger, 1975 and up Granada, 1974 Maverick, earlier 70's Torino or Ranchero with 14" rims & front disk brakes might work also. Most of these are 6 inches in width.

1995 Ranger wheels go right on and they’re 14”s and our hubcaps fit right on.

Dave, This is all very interesting. I didn't know I would need a proportioning valve with a drum drum system.
