What procedure to remove front brake drum - 53 p4

What procedure to remove front brake drum - 53 p4 - 21/11/20 05:08 PM

I have a 1953 plus 4 with steel wheels.

I went to remove the front offside brake drum today, but was confused (easily done!).

Loosened the brake adjust, took the wheel off. Expected to see one or two countersunk screws that needed to be undone to allow the drum to come off - but I could not see those at all. Pressed on anyway, hitting the drum in various directions with a heavy hammer and a block of wood. The drum rotates so the brakes are not frozen. But of coursse it does not want to coe off. y plan is to use a hub puller tomorrow but `maybe I just can't see the countersunk screws under the paint. Are there any drums that don't have these countersunk screws? Photo attached hopefully. Do I need to remove the big nut on the axle? I was assuming this was just a dust cover.

That's what I'd expect too. The rear drums certainly have two.

Looks like the version where you have to carefully unscrew the soft alloy nut (very fine soft thread) you can see, this then gives access to the castellated inner nut with a split pin through it, drive the pin out & remove nut, may be a thick washer behind, then the drum should wriggle off

On mine (steel wheels but discs) that procedure would remove the entire front hub from the stub axle.

The hub and drum are one piece on cars of that era.

You have to remove the aluminium dust cover nut, and then remove the split pin and undo the hub nut

You can then pull the hub and drum off
The wheel bearings are not taper roller type and have a sized spacer between them to set preload, so a degree of knowledge is needed to tighten them back up

Is the preload procedure documented somewhere ?
