Default Brake Drum indicator?

The tires on my recently acquired 64 convertible are from 2004. They look new but sitting around for 13 years can't be good for them. While the car is up on jacks, I'll use the opportunity to check and bleed the brakes and replace the rear shocks (already replaced the front shocks).

I have the aftermarket knock off look a likes. I tried to get the spinners off with gentle persuasion. No doing. Turns out, the spinners are pinned which was obvious once I removed the center caps. Glad I did not bring it to a tire shop. Pretty sure they would have used a big hammer.

Checked the brakes and all looks good. But I was wondering whether this indicator on the brake drums has any meaning? Is it supposed to align with something on the hub?

Thanks, Gerald

148 hits and no answer eh?

I don't know why it's there but I know it's a handy place to start with a thin tool to get under that tab and pop a stuck brake drum loose when it's stuck around the axle hub.

That may be it's purpose. May not.

That is its purpose. Used to be a standard tool for prying it off it needed. You use two of the bars with hooks to do it

That makes sense. Good to know.

I'm actually surprised how well the drum brakes work. No pulling and they bite hard when applied aggressively. I'm sure the power assist helps.

You should also have a drum brake gauge. It the drum becomes too large you could actually lose your brakes. It's not common but it could happen.

A lot of these drums are really old. Measure them.

Drum or disk if they can lock up the tires in a straight line they are both doing their job The advantage of discs are that they self adjust themselves, fade less readily and work better after submersion. Not things our cars are usually concerned with.

This was nagging at me as I remember seeing this in a manual.
I had to search through many manuals until I found it.
No mention of it being used to aid in removal.

I have seen the picture in figure 16 many times. What does it tell you to do with it and why?

I would guesswhen these cars were new that the lanced hole in the drum was positioned over the drilled depression in the axle. Maybe only as a reference as to how it was originally assembled.

I think that's the way it was but it's been so long since I've seen a new car like this, I can't recall. In any case, other than reference, what would that orientation do for you?

Plaidside, thanks for looking it up. I checked and, yes, there are reference holes in the front hubs, none in the rear hubs. I'll assemble them as the manual describes. It is a bit of a mystery but it can't hurt.
