Question, how do the emergency brakes work on a '48 F4?

When I got truck someone had put a 302 & AOD in it and I'm trying to figure out how to put emergency brakes on it. I don't see any "spot" for the cables to go through the rear drum backing plates. Any help would be greatly appreciated.

thanks,

 

That would have been a transmission mounted parking brake, don't know of any way to integrate them into the rear drums without changing the rear-end to something newer.

 

On mine the Parking Break (original) is at the back of the manual transmission. It is a Band that tightens down around Drum.

Probably not what you were wanting to hear, but there is no provision made for auxiliary braking on the rear axle. I can probably post a .PDF of it from the 1948-52 Ford Parts Manual if it would help.

I'm looking at it now: 1948/56 Ford Truck Parts Catalog: Illustration Section 36, page 47.

btw: For y'all that don't know...This same catalog is available on a CD from hipoparts.com for less than 25 bucks.

 

wow, definitely not what I was wanting to hear.

Cass, if you don't mind posting the .pdf I would appreciate it.

So if I wanted to use the stock rear I'm pretty much out of luck on installing emergency brakes. I guess I could carry some blocks of wood around with me to chock the wheels when I park.

 

Here you go...
Hope this helps.

Ok, just one more question, the diagram shows a hand operated emergency brake, does a floor mounted emergency brake handle opperate the drum style emergency brake as well?

 

My parts catalog shows a floor mounted parking brake lever for an F4 (TL).

There is no handbrake type lever mounted to the dash or parking brake cables for an F4. It's all controlled by the lever on the floor.

Parts catalog illustration SECTION 26 (not 36, that was a typo) PAGE 47.

That pic posted is for the hydraulic brake system for a P Series Parcel Delivery (J, JH, JL), not for an F4. F4 = ID in the parts catalog as a TL.

The parts marked 2269 are steel brake lines, not cables.

 

Ok, thank you!

 

Sorry, everyone, not trying to confuse...

I have the floor mounted Parking Brake Lever as well. That was just the most complete diagram of an entire brake system I located.

Here is an illustration of the Parking Break (1953/ Models T, TH, THZ) showing the Lever and Break. Then the 2nd illustration is the bottom part of the page referred to above re is just the 48-52 Parking Brake (Models J, T, TH, TL, W, WH), showing only the Parking Brake.

hivolt5.0,
I ran across this looking for something else, thought it might be another way to go.

Axle Identification Chart

FORD 9-INCH
The venerable Ford 9-inch is both readily available and strong. Later models have bigger axle tubes and stronger housings. It was standard under 1966-88 F-150s and Broncos. It also came on many vans and the Lincoln Versailles (a popular axle for swapping because of the Lincoln version's disc brakes with parking brake).

Don't know about the wheels, that may be another problem. Just food for thought.

One of the other guys may have a better idea.

FYI...I'm not picking on you, because you prolly don't know that some of this info is bogus.

Ford 9 inch introduced in 1957. It was standard equipment on 1957/82 F100's, 1975/82 F150's (1975 was the first yr for the F150), 1969/82 E100's and E150's. Also used in Bronco's.

In 1983, Ford introduced the 8.8" integral rear end, so both the 8.8" & 9" will be seen in these models only thru the end of 1987, when the 9" ended production.

The 9 inch was also also used in certain passenger cars from 1957 thru 1979.

Because of the narrow frames on 1948/56 trucks, the F100 1957/72 9 inch is the one to use. 1957/67's have 1 3/4" rear brakes, 1968/72's have 2 1/4" rear brakes.

1973 and later 9's have a wider axle housing to match the new frames these trucks have.

1976/78 Granada's & Monarchs (as an option) and the 1977/80 Lincoln Versailles came with a 9 inch rear end and discs.

The axles bolt pattern is not the same as F1 & F100's used (4.50" vs 5.50"), so changes have to be made. These (midsized) cars axle housing are also shorter than F100's used.

Most passenger cars 9's will not work in trucks because the axle housings are much shorter, and many of these cars have either a 4.50" (most common) or 5.00" bolt pattern, rear coil springs, among other differences.

 

Well,

You don't have many options for a parking brake.

Look at the following picture and you see how I'm doing it. That's about your only option if you decide to stay with the AOD. (that is, get a Superduty parking brake and bolt it on the back......it bolts to the same casting that a 4x4 transfercase bolts to.)

My trans is an E4OD.
I'm assuming that the same 4x4 adapter will bolt to an AOD.....


Cheers,

By the way.....if you want to use an E4OD, you'll have to get a trans controller like THIS ONE Which by the way, is the one that I'm using...


This is what is going in my 55 F-600

 

wow, you guys really are a wealth of knowledge. Makes you wonder how cars and trucks got restored before the advent of the forums.

Thank you all for the info. I have access to a stock transmission for an F-4 so I may go take a look at it to see if it still has the emergency brake drum on it and then see if there is a way to adapt it to the AOD.

thanks guys!

 

just another option, you could use a disc, (rotor and caliper), on drive shaft. hook up a linelock and your all set. rick- nice job on the trans!
