Technical Ford brakes Buick drums

Hello all,

I have searched and haven’t found an answer. I have 13 inch Ford front brake backing plates with Buick drums. The machine work has been done and the drums fit. My question is are these f250 backing plates? The holes for the wheel cylinder are not parallel to each other they are offset. I have wheel cylinders that have parallel mounting holes. I would rather not drill the backing plates and get the correct wheel cylinders.

 

The F2 and F3 brakes were used with the 12" diameter Buick drums. Perhaps something like this? I would want to check wheel cylinder bore diameter to see how it matches with your master.

Thank you Jim.

 

I am not saying that I know it's correct for your backing plates. Just that those type of things are out there. My F2 backing plates have the straight across wheel cylinder mounting. RichB on here would be the guy that would get you headed in the right direction.

 

Jim: Over the years I've done quite a few of these before the repro Lincoln backing plates became available. These backing plates originally used a single puck wheel cylinder. While I did redill some of the backing plates for the F150 dual puck wheel cylinders I also did quite a few with the single puck cylinders and they worked fine. I figured if they could stop a 4-5000 lb truck they would work work on a 2500 lb street rod. I know most of the HAMB guys prefer the dual puck cylinders but since you have the backing plates chromed I would be hesitant is redrill for fear the edges of the chrome might peel. In my opinion you'll be good with the original style wheel cylinders. Gary at Cornhusker

 

Thank you Krylon32 for the information. I have a box a brake parts that came with the car. 12x2 inch brake shoes, brake shoe retaining hardware and some springs. The parts that I have look to be early F250 parts from all the diagrams I see online. If I were to go the single puck cylinders what year and model and year would you recommend? Do you think its possible to run the dual puck 49-52 Ford truck wheel cylinder with the correct stagers holes?

 

Here is a picture of the F250 style brakes that I found here on the site.

 

@RICH B , any thoughts for this rodder?

 

That picture is of a rebuilt set that RichB sells. It is a dual piston wheel cylinder Bendix style setup. That's the setup I have. But as Kyrlon32 said, if you have the parts and correct springs, the single piston brakes will work if you don't want to mess with the chrome backing plates.

 

Those '49-'52 Lockheed wheel cylinders are incompatible with Bendix brakes.

The wheel cylinders to use are Raybestos WC36074 & WC36075.

When putting them together be sure the chrome doesn't interfere with the freedom of the anchor pin to move during the shoe centering adjustment.

If the springs you have are used, I would replace them with new ones. Note the adjuster spring is specific to these brakes.

 

Thanks Rich. I need to buy everything to make these brakes work. I have no hardware except for the brake shoe retaining pin. The brake shoes I have are made for the dual puck wheel cylinders. Is there a specific model and year vehicle I can reference to get the parts I need. Thank you again.

Here are some vehicles that recommended wheel cylinders fit:

It's been several years since I have done the F250 backing plates but I was able to get the shoes, wheels cylinders and springs at my local Auto Value store. I did it several times. I did have a couple of very experienced parts pros who were willing to take the time to find what I needed. Wish I'd have kept all those numbers but once I started using and selling Boling Bros Lincoln brakes I quit doing the F250's.

 

The shoes are the same, whether used with either a single or dual piston wheel cylinder.

Parts I use.
Brake shoes: Centric 11200330

Spring kit: H7139 Use the retract springs, use the shorter pins with the hold-downs
throw the rest.

Adjusters: H1500

Wheel cylinder push pins: H1414-2

Adjuster spring: 1D-2049 This is an "obsolete" spring in the replacement parts market; but is available from Gotham Auto Parts. If you do have the original springs there is no reason not
to reuse them. I can help you with these springs as well.

The "H" part numbers are used across most all brands of brake parts; Raybestos, Carlson, etc. NAPA uses their own numbers; but can cross the parts.

I usually get most of my stuff from RockAuto; but the parts should be available from your favorite parts place.

 

I took a better look on my desktop at the picture of your backing plate. It looks like there is some; but not severe wear on the shoe support pads. Obviously can't weld them up now; but it might not hurt to tune them up a little with a grinder. Don't need the shoes hanging in the future.

I've seen more than a few backing plates where they were sent out for powder or chrome without reconditioning the wear pads first; guessing drum brake maintenance is a never learned skill for many of the younger generation.

 

Listen to Rich B he's our resident early Ford drum brake guru.

 

Thank you very much for your help and thanks to everyone else who helped or gave their opinion. This car is like a big puzzle that someone started and never finished and I only got some of the parts to put it back together.

I am also missing the center stud that the brake shoes rest on at the top. I'm guessing the 1952 F250 part will work as well.

Thanks again guys.

 

Locating those anchor pins might be interesting; at least I have never found any available anywhere other than on another backing plate. While, anchor pins from other Ford 10" & 11" brakes can be machined to work as an alternative; probably easiest would be just to locate another pair of backing plates from a '52 F-2 or F-3 or '53-'56 F-250 or F-350. All 12" front and rear brakes in those years use the same anchor pins (1D-2027-A) and washer (1D-2029).

 

Thank you again for the info.

 

Are the anchor pins used by Boling Bros on their Lincoln brakes close?

 

A HAMBer had some stainless anchor pins he made for sale in the classifieds. Might fit?

 

At one time Jeremy @jebbesen told he had a CAD (?) file for machining anchor pins; wonder if he was the one that made the stainless pins?

 

I bought 2 pairs of the stainless pins but currently can't find the info. They are perfect but expensive.

 

I will check the classified section. Thank you

 

It would be nice if I could find a set.

 

Does anyone know the measurements for the F2 anchor pins? I found the F1 style and they have a measurement.

 

Needs this?

Here is a link to some info on the stainless anchor pins from ages past.

Cut the shoulder of an F-100 pin down to match the thickness of the shoes. The modified pins will take a shim washer to bring them up to the correct height and require an external star lock as a split lock will be too thick.
