1952-59 Ford 4 stud to 2 stud Master Cylinder Adapter

Hi everyone,

Been awhile since I have posted in here, but after finally finishing school and landing a full time job, I can finally give my 53 the attention it deserves. Iv been looking at doing a disc brake conversion and adding a dual reservoir master cylinder, but almost all modern master cylinders are a 2 stud. Does anyone make a 4 stud to 2 stud adapter plate? I found some on summit but not sure if they fit, as it seems most of them are built for mopars.

As far as doing the conversion, are there any headaches I should be aware of before doing a disc brake conversion?

Thanks, Luke

 

I put a dual master cylinder on my 56 and used only the lower two bolt holes. I put matching bolts in the top two holes. The MC push rod lined up perfectly with the pedal.

 

The top two holes also secure the pedal ***embly bracket,the lower two holes are the master cylinder and the lower part of the bracket. No adapter needed. Watch the video in the "Sticky FAQ"

 

No adapter needed as others have said. Just put bolts in the upper holes to hold the pedal ***embly

 

Thanks everyone! I appreciate it! I didnt realize this. I figured it wouldnt line up.

 

I mounted my master to a plate that also picks up my clutch master, it really stiffens up the firewall.

 

Aren't the top two bolts to secure the Blinker Fluid Reservoir?

 

Does it still stink in Manteca from the Sugar plant ? I lived there in the late 70's there was a plant behind the house that processed peppers. Back then I worked at the Dodge dealers.

 

Nah, That's been gone for years. Lots of houses and a Home Depot/Shopping Center are in place of the Spreckles plant.
You wouldn't recognize the place. I moved up here in the 90's and it's a LOT different from then, even.
SO many houses out here now that it really fixed the Tule Fog issues. Take away the crops next to the freeway, no more moisture available to make Fog

 

Always liked the wine from Delicato up the road a bit. After I left Dodge I was working in Lodi the fog on 99 was really nasty sometimes you were lucky to see past the hood in that stuff. I guess the little town grew up, back then population was barely 20,000.

 

I am looking to do the same as the OP on my '52. Should I be looking for a MC with a certain size bore for the rod?

 

you will find your answer in the FAQ section a word of caution the section is for viewing only NO QUESTIONS good luck

 

If you still have all drum brakes the master cylinder you want is at Autozone part number M1485( 1967 Mustang) this is a rebuilt,why you ask ? The majority of rebuilds are USA made castings which are better almost all new masters are made in India or China. With this master you will use your stock 1952 push rod this video will show you what is involved:

 

I found that post jeffb2 and watched the video after creating this thread. Only issue is this will be going along with a disc conversion.

54vicky, so what you're saying is this section isn't for asking for help from fellow 52-59 Ford owners? Most of the posts i see are from people asking questions. Just trying to learn the rules on this forum

 

The "Sticky FAQ" is for information ONLY if you have questions ask on our regular forum. If you are converting to disc you should probably go with this: https://www.ebay.com/itm/1952-72-Fo...=233213957678847e6397ea694a84afa85cbb4d84beaf

 

You will need to install residual valves for the rear drums. You could go fancy this comes with the proportioning valves included https://www.ebay.com/itm/1952-72-Fo...e:Ford&hash=item363c946508:g:IqkAAOSwLpxbZFcZ

 

Forgot I was on a sticky when i made the comment, i see the issue now. I'm used to forums locking stickys from comments. So i wasn't thinking about it. My bad. As far as that mc you linked, i was thinking of not going with a booster and just going with an mc with a proportioning valve. I'm just not sure what size bore the stick rod is

 

Autozone's M1512 is for front disc with rear drums and manual brakes. It was used on 1972 Mustangs they were internally valved they do not require a proportioning valve.

 

Thanks JeffB2 and everyone else that sent me info. I haven't started the conversion yet, but Im sure I will have plenty more questions once I dive into it. Been way too busy at work. Thanks for the help!

 

Thanks JeffB2, getting ready to install disc brakes on the front of my 56 and did not want a power vacuum can. Your info on the MC is really helpful and I ordered one today. The rear brakes are from a Ford F-150 and are the same diameter as the original, just wider. All of it is on the 8.8 Explorer rear end I've already installed. I hope that continuing with the 11" and not 10" rears the 70-72 Mustang had won't mess thing up.
Still researching a front kit that will bolt on the stock front spindles and there are a lot of guys selling them. RB in South Carolina has a lot of knowledge along with Dave

 

Hi Jeff.. I too am looking at doing the disc front w/manual brakes as poor vacuum with a Mummert cam on the Bird. I know you know these details pretty well but the #1512 Master on all the sites here (NAPA etc.) all show it being for drum/drum manual. Is there a difference as far as having the internal valving to not require a prop valve.?

 

56BIRD, I saw that too. I used the Oreiley's website and put in 1972 Mustang and did a search. Here's the page that came up https://www.oreillyauto.com/shop/b/...6ed/1972/ford/mustang?q=Brake+Master+Cylinder

It looks like 11272, 1378 and 1378B are all disc/drum. They all say power though as well. Does that mean that I would have to run a booster with these?

 

I'll be the first to admit that I haven't seen everything, but I don't recall ever seeing a factory disc brake car that wasn't power.

 

Not very common but they were out there,more discussions https://www.jalopyjournal.com/forum/threads/manual-brake-master-cylinder-help.646665/

 

It seems like the best/easiest option for manual brakes with disc/drum may be to just go with an MC and proportion valve

 

Thanks Jeff, there is always something to learn.

 

Granadas came both ways. Power and manual.

 

Probably gonna go with this guy. https://www.jamcosuspension.com/products/sfID1/33/sfID2/39/sfID3/234/sfID4/37/productID/780

Unless anyone sees an issue with this set up. Hope to hear from you soon so I can get it ordered. Disc brake parts came in today, so I am itching to start installing it. Hoping to get it done by July before I go to Japan for 3 weeks.

 

Same thing as Jamco without the markup: https://www.ebay.com/itm/Corvette-S...692698?hash=item210a3d081a:g:RrsAAOSwAuNW6y~~

 

Bought and returned. Rebuilt in Mexico (shipped from Tiajuana) and cast in China.
