DIY002C retrofitting a new dual master Cylinder.

This is a great unit to replace a Bendix Treadle-vac.
Universal 7" single diaphragm power booster with 1" bore master cylinder for disc/drum applications. The fluid reservoirs need to be the same in size and or volume. Additionally there is no proportioning valve needed ...... nor is their a residual valve.
There are many suppliers out there. You can source these items separately and get them for a good price. Be sure it is designed for a Drum / Drum system.
BTW I chose to use a dual diaphragm booster system.

This is a view of the front of the booster. There will be an additional part supplied with the Master that goes here.

Make sure the Master fits in this cavity.

You will need to make an adapter plate in order for this to work. I used the old back plate from the original Treadle-Vac unit

Here is another view.

Bolt plate in place as shown.

Attach the Master

I cut to length and threaded the factory connecting rod. I made it the same length as the original unit.

This is why you need to change your brake fluid

Brake light switch Part #80172 Is a bit more reliable than the old pressure switch. They Leak.
20190624_163457.jpg
There is plenty of real estate in the Lincoln to Mount this unit
20190601_122050.jpg
You can mount the pressure switch as shown if you prefer.
20190624_123151.jpg
Here is the Junction where one rear and two front brake lines meet.The line running up to the master I will reuse. For the two front brake lines. I will block off the rear brake line port with a plug. I will add an additional junction for the rear brake line and extended it up to the master. The line traveling down is the right front brake. The rear line and the left front line enter the original junction block on the far side of the fire wall not visible in this picture.
20190704_210729.jpg
The line on the right is the rear brake line . The one on the left is the Left Front. This the the view from inside the fender well.
20190704_210556.jpg
I will disconnect the rear brake line and plug the port. Using a new junction box I will route the line through the fire wall up to the Master.
20190706_102651.jpg
I fabricated a mounting bracket. This is how it will mount. SOME OF THESE PICS TURNED SIDEWAYS!! ? Not sure whats wrong.
20190706_104155.jpg
Bore a hole through the firewall.
20190706_105620.jpg
Attach the junction as shown.
20190706_113504.jpg
Remove the rear Brake Line andPlug the bottom of the Junction on the left. Move the rear Brake line over and attach it to the new Junction Block on the right. Notice the plug on top.
20190706_105756.jpg
Here is the business side. You will need to make a connection from here to the master.
20190706_112044.jpg
There ya go!

Job Done!

I'm going to try a late model Crown Vic unit. There are a few good ones in a local yard and they look and mount similar to the one pictured.

Might be a low cost alternative. (adaption required)

That will work on some models .... However on cars like my 1959 Lincoln. I have 4 wheel drums ......So the fluid reservoirs need to be the same in size and or volume. Additionally there is no proportioning valve ...... nor is their a residual valve.
The residual valve will cause the brakes to drag.
On such a massive beast I would be happy to just stop.! Keep in mind the above unit pictured is designed for use with drum brakes....
There is a guy that used the above setup with much success, No proportioning valve and no residual valve on a 1960 Lincoln.
On the original set-up the one master operated all four drums at once. I do believe an adjustable proportioning valve would be best.

They don't list a master/booster specifically for a '58 to '60 Lincoln with 4 wheel drum.

The pic you posted looks like their model 1501 universal for disc drum.

Another source for that assembly is Speedway Motors. http://www.speedwaymotors.com/Single-Di ... ,1983.html

The crown Vic unit doesn't have a built in proportioning valve, none do, and with a 10psi residual valve for the front it should work just fine.

We'll see

Hmmm.... 1" bore is quite a lot larger than original .62" bore. I bought a retrofit 7/8 m/c from an 88 buick regal which also has the resivour angled to exactly match the angle from the firewall to horizon, and without the large vacuum resivour connected its a bit sketchy. This is with an aftermarket dual diaphragm booster which is miles more boost than stock, and more than similar single diaphragm units.

Nice job!
I put a ClassicDiscBrakes power-front disc kit on my Edsel Corsair. Other than making a custom pushrod and some slight tweaking of the caliper mounts it was all there and bolt on. Works great.
