FYI

If anyone is interested Rather than cutting holes in the firewall for a dual cyl and swing pedal, I am installing a '72 Ford Torino (drum brake) dual master cyl #10-1519 (Advance Auto) onto the '37 to '47 Hudson under floor brake pedal assy by doing the following...Cutting a 1/4" mild steel plate 3 3/4 H X 5 1/2 W, countersinking 3 perimeter holes using button head (flush) allen bolts (to retain the adapter onto the original Hudson pedal bracket), then hole sawing a 1 3/4' center hole and drilling one hole on the left & right side of the adapter to bolt on the wider flange Torino cyl.

The Master Cyl comes with a new push rod that needs shortened to aprx 4 1/8" .The stock clevises will need re-adjusted for pedal height. The mechanical rear brake feature can still be retained if desired. (If you dont want to make an adapter you can buy one from ECI Inc.) (www.ecihotrodbrakes.com). Its Listed for old Fords, but the Hudson Master cyl is identical.

Naturally you need to seperate your front & rear lines and if Disc are utilized the Master would be a different number. Addittionally, I discovered the larger Hornet 11 x 2/ 1/4 front brakes hubs & back pl;ates will interchange with swapping one brg race/cone providing greater braking.

If you can put this on the Hudson site,many will be happy!

can you put a remote filler on it?

And here all along I thought Hudsons only made Stepdowns :rolleyes:

Nice information to post out there for the earlier Hudson users. Do you have the ability to put some pictures with your description?

Safety Updates:

Regarding remote fill for master cyl.... Great idea, but not sure if possible with the 'clip type' lid, but certainly deserves some thought..

Regarding pictures...

I could insert the adapter & master cyl back onto the '37 pedal assy I utilized to fabricate then take a couple pictures...

Regarding updating the '37 and '47 with larger Hornet Front Brakes..

The backing plates bolt on but '50's hubs are deeper requiring adding 1 (grade

3/16" washer as a spacer inside the castle nut after utilizing the '37 inner brgs and the Hornet outter brgs.

I have also been using mid '80's Ford Bronco rear sway bars on my '37 & '47 Hudsons ahead of the rear end. The Bronco U-Bolts clamp facing rearward over the housing tubes near each side of the 'pumpkin' then the side links go up to the frame needing only a pc of channel welded or bolted. Handles like a sports car....

@Olracer - You mention that an adapter can be purchased from - www.ecihotrodbrakes.com -

"...(If you dont want to make an adapter you can buy one from ECI Inc.) (www.ecihotrodbrakes.com). Its Listed for old Fords, but the Hudson Master cyl is identical."

Do you recall which adapter are you referring to?

FYI
ECI may only sell the whole 'under floor Master Cyl Kit' including their under floor Brake Pedal Assy. I made the Adaptor from a pc of mild steel plate as mentioned above. I posted some pictures a few Yrs ago but this is the only picture I have now. I retained all the original 'secondary' emergency brake system too....

@Oldracer - thank you. I've been looking online, mostly background research. I looked-up the part no. you mentioned, and the example (photo) it showed is the same as the unit shown in your picture above. That appears to be a master cylinder for a disc/drum configuration (smaller front-well for the disc brakes). Do you have disc brakes on the front of your truck?

From your photo, I see that the connections for the brake lines on the master cylinder are on the right. Was the position of the connections a factor in your selecting this particular unit for your use?

Here's a picture of another Ford master cylinder, for a drum/drum unit (below). It has the connections for the brake lines on the left (as it would sit in the car). This brings-up possible fitment issues, as the master cylinder may be too close to the frame (an unknown):

On ECI - If you go to the bottom of the page in the link shown below, it looks like they sell adapter plates - I'm just not sure what I'm looking at or looking for. Guess I just need to do a bit more research.
www.ecihotrodbrakes.com - adapters

As you've done, I have a '47 pedal assembly unit (has been sitting in my scrap pile for quite some time), and plan to do much of the fitment/configuration from that. It will be put into my '39 - however according to my uncalibrated eye, the units a very, very similiar.

So much in the 'planning/configuration' stage - hopefully, it will all 'come together' eventually! LOL! =))

FYI
Their Top '3 hole Adapter' is what I made from a plate. The Torino master cyl was for Drum Brakes and the Part # is listed above. It was a simple swap. I had to shorten the Torino push rod then thread it for the Hudson clevis then adjusted for slight free play.

PAULARGETYPE

I DID SOME CHECKING THE MASTER CYL IS ONLY $21 AT ADVANCE AUTO PARTS THAT IS HALF THE PRICE OF THE ORIGNAL MASTER

Ol racer

46 pickup,
Buy the Adaptor Plate because EZ'r then Fabing one and use the Drum/Drum number I provided since the line fitament didnt give me any problem. I think I bought at Advance because of price Paul mentioned. Do the upgrade and keep the original Emergency Pedal Feature as I did.
Ps: I bought a remote Fill' assy at a Swap Meeyt but never installed because never needed fluid after original Fill. (It can be easily accomplised with a funnel on a hose)
