Donald:

IT's been a LOOOOONG time since I've adjusted the brakes on a '40 model Ford but here's what I remember.

As I recall, they have the starwheel adjuster like later drum brake systems.

- Jack the wheel clear of the ground so you can turn it.

- Remove the oval rubber or metal plugs that cover the adjuster holes.

- Using the angled screwdriver-like tool, turn the star wheel in the direction to spread the shoes. Keep turning the star wheel until the brake is almost locked then back off the adjustment until there's a moderate drag.

This is all assuming that the centering adjustment (at the top of the backing plate hasn't been messed with). The centering adjustment shifts the front and rear shoes back and forth so they both contact the drum equally.

If the centering nut has been fiddled with, loosen it and turn the bolt one way and the other while easing the spread adjustment until you're at the point where both shoes are touching the drum at the same time.

As I recall, that's all there is to it. Most times, the centering never has to be changed from the factory setting even when changing shoes.

Hope I'm right and that this helps.

Take care - Elden

Per my "Motor Auto Repair Manual", Ford used Locheed type hydraulic brakes from 1939 to 1948. The brake shoes are adjusted by turning the adjusting cams - no star wheels. The cams are turned until the brake shoe is locked against the drum. Then, the brake cam is backed off in the opposite direction until the durm/wheel is just free. This is repeated for each wheel.

I think those brakes have two cams on backing plate. Place a Box end on each bolt head and turn until the wheel locks , then turn back a little. If I remember right, on each wheel the front cam turns counter clockwise and the rear turns clockwise . I got my drivers licence in 40 Ford in 1947 .hope this helps. Bill H.

Bill has it right.Some of them have two lower anchor cams,with a flat sided stud and a jam nut.Don,t mess with them or you will be in trouble (they are only used when you you install new shoes.

Wow, Donald - I was really El Wrongo on that one!

I DID say that it'd been a lot of years, didn't I?

I know this is an old post, but there's a great article that explains step by step the procedure to adjust these brakes.

There will be people looking for as much of a definitive guide to this work as they can find for a long time, so here it is.
