49 F1 Brake issue

[jtminor]

Truck pulls sharply to the left when applying the brakes, assuming the right brake is not functioning. I have no experience with brake repair, where should I begin this investigation. Any help will be appreciated

You'll have to pull the wheel & drum & have a look in there for signs of wheel cylinder leakage. The old type brakes aren't self adjusting types. There may be wear or lining contamination problems.

Check the hoses going to the front wheels.

Old age. They can collapse internally, thereby “necking down”on ID and causing a restriction. I once chased this issue on a brand new hose that was improperly manufactured also.

Check the keft front brake for leaks if the car is pulling to the left.

Buy some new cylinders and hoses and fit them. They're cheap. If the shoes are good re-use them.
You need to tackle this job because you need to build up the familiarity with the old stuff if you want to drive with confidence.

Inspect both sides and only dismantle one side. Then you have the complete side as a pattern if you can't see how it goes back together.
To be honest, that is one of the simplest setups there is so would be a good one to have a go at if it is your first time.

Looks like the brake shoes are backwards, short shoe should be on the front.

Any tips on removing the springs.......

[jtminor]

Just bought the truck, last owner had it for 48 years... I don't know when the brakes for looked at.....

Floor jack is in the front of the truck in the picture

JT, you can get a simple set of tools for the brakes, there is a doodad that winds the springs off and helps you slip them on.

These pliers have the ends like the tools you need. Go to your local auto parts place and ask for old type brake tools.

The round end takes the springs off and the shaped end puts them on.

Yes, on Bendix brakes, short shoe toward the front.

[jtminor]

Problem ... left front drum won't come off, bigger problems?

[tubman]

Sounds like a wear problem. Have you backed the adjusters on that wheel all the way off?

[jtminor]

No I have not, will try in the morning.....

Thanks

[Mart]

Do you know how to back off the adjuster? It's that star wheel near the bottom on the link. Put a screwdriver blade through the slot in the backplate and rotate the star wheel so it shortens the link.
Then the drum should come off.
Use the right side as a pattern so you can see what should be happening.

If the vehicle pulls to the left, the right side front brakes are the problem.

Maybe it's the camera, but that whole brake assembly looks rotated to the rear too much. The wheel cylinder should be parallel to the top of the grease shield, too.

[FlatheadTed]

If you don't have pliers grab the extended part at right angles with vice grips, two hand s right pulls left holds

F-1 and F-100 backing plates are clocked to the rear on the spindles to permit the brake hose to clear the top kingpin boss on the spindles.

New issue. completed installation of front brakes, new 11" shoes , new wheel cylinders, re-surfaced drums.
new seals.... now drum will not fit back on... adjuster is cranked all the way down.

What do you think went wrong..?

[jtminor]

new photo of install....

I start out by putting the adjuster in properly. Sometimes it is fun learning about unfamiliar stuff.

[Mart]

Good catch rich B. It's good when the solution is simple. This is a good illustration of the power of a photograph. Without that we would all be going down the overly thick lining route.
JT: You will observe when fitted correctly the spring rests on the star wheel hence stopping it from moving unintentionally.

you guys have made my day, thanks for your input, learning as I go....

Have a grateful day!

You're welcome, Jim. That's what we come here for.

That is an example of why it is a good idea to only do one side at a time, so you have an example of what goes where.

But; that takes all the fun out of it.

I know, I tend to take things apart, than get distracted (for a long time!) and then it becomes a puzzle!!

[jtminor]

Now bleeding brakes, back bleed fine, front, nothing, no fluid coming through, lines seem to be alright, new brake cylinder appears to be dry on fluid, MC has fluid, I did something wrong.....

[1948F-1Pickup]

I'd do yourself a favor and invest a few dollars in a set of speed bleeders.
Will make your life way easier bleeding the brakes.
They're 3/8-24 on the F1......... SB3824L
I believe those are the ones on my 48 truck.
