im looking for a set of brakes for a project...but would like a lil more info if anyone has any ideas.
i know the early f2's had a single piston brake wheel cylinders on it.
and i know the rear's had dual piston wheel cylinders on it.
my question is, does the rear also have ebrake cable wires or is the ebrakes on the axle? any one have pics of the f2 rear backing plate 1948-52
 
Here's what the Parts books show. It clearly shows a cable for the rear. 52's were different from 48-51. Not sure if the driveshaft-mounted e-brake was an option on F-2's with the crashbox 4-sp, but F-3's could be either way.

some did have a cable operated parking brake but it was later. most of the early 51 to about 56 had a drum on the transmission.

the last one i got rear backing plates with the cable was off a 59 F250 but the fronts wont work. you have to use fronts from a 51 to 56 because of the spindle.

as for doing away with the single piston wheel cylinder on the front you just change to a later wheel cylinder and drill one mounting hole

the 48 to 50 F2 had the old style 48 car backing plates with 8 lug drums.
 
alright, so the f2's between 1948-56 rear backing plates (with ebrake cable holes) i can use on f1 spindles?
does any one know the overall size of the f2 backing plates?
i know they take 12" drums, but i wanna know the size of the backing plate.
 
the f2 plates fit the f1 spindle, i wasnt sure if its an actual f2 backing plate because it has ebrake cables and i thought all f1 and f2 had them on the driveshaft.

51 to 56 f2/f250 front. 48 to 50 f2 are the old style lockheed like 42 to 48 car.

48 to 56 f1/f100 are the same with different drum/hub.

It can be alittle confusing but you will figure it out down the road
 
Another common trick was to use lincoln rear brakes on the front with out the parking brake becUse they dont have the deep offset like the late lincoln fronts that require a spacer.
 
Some mis-information in the above. The drawing is lables "F-2", incorrectly. F-2 and F-250s are "Bendix" type, self-energizing brakes. The brakes in the drawing are old Ford "Lockheed"-type.

Below...the black backing plates are FRONT, 1955 F-250. Note the brake cylinder mount holes for SINGLE piston cylinder. The primered plate is an F-2 REAR plate...note double-piston cylinder mount holes. DD

Not misinformation; just different info. '53 -on are different than 48-52. See Skidmark's post #7. OP is asking for F-2 info, which is 48-52.
 
Yes 48 to 52 is the F. 53 and up was called a F250.

The confusion is the 48 to 50 f2 front brakes are the early lockheed style. The bendix 12" self energizing brakes started in 1951 f2. But the 11" self energizing bendix brakes were 48 and up on the f1 and up to 56 on the f100. 57 has a different style spindle that wont jive with early spindles


To fit early spindles you need 56 and earlier or you can run rears on the front up into the early 60's f250.

I think his main question was were to find 12" bendix with a parking brake cable.
 
Also remember you have to file or grind a little out of the center hole to fit them on early spindles. Its very minor

The F-2/F-250 12" Bendix backing plates measure 13-5/16" diameter.

I have never came across a pre-'56 that didn't have a 4 speed and trans mounted E-brake; guess I will have to check out some later '50s-early '60s trucks, any idea of year range and do you know if they all went to backing plate mounted E-brakes or just the the auto trans equipped trucks.

Of course you could just make your own E-brake set-up, here's some on a banjo rear.

I've found that if rich b says something about ANY of these old Ford-type brakes, you can pretty-much take his info to the bank. DD

F-250 fronts bolted right onto the round spindles on front of my '40...no grinding required. DD

The rear plates are the ones that have a slightly smaller center hole.

The rear plate bolt pattern is also slightly different, the holes need to be elongated to use the original 1/2" square headed backing plate bolts, or 7/16" bolts will fit as is.

The front plates will directly fit the early spindles.
 
That service note kinda sound like its talking about the lockheed brakes by the years mentioned.

All of the larger pickups ive parted out with 4 speeds all had the transmission mounted brake.

A few years back I built a 34 pickup with f2 or f250 brakes wih the rears off a 57 to 60 that did have a cable operated parking brake.

If you find one in a junkyard make sure its got all the parking brake hardwear. Pieces are hard to find

I have also seen those 12" bendix brakes on Studebaker trucks. I learned that fro. A stock car racer that used them with buick drums and floating axles
