SV: Brake Drum Machine Screws

[Bo Strander]

Hello Ed,
This is the typical european way of attaching drums back in the good old days.
It's obviouse that the screws doesn't have any major clamping force, my guess is
that it's just a simple way of keeping the drums in position when the wheels are
off.
Anybody else with a better idea?

I have never before encountered brake drums that are mounted like the Amphi
drums. What is the purpose of the three small flat-head machine screws that hold
the drum to the spindle, independent of the 5 wheel studs? Maybe this is typical
of German cars?

Umm, replying to my own question, as I haven't seen any replies. Anybody have
any idea why our Amphi drums are designed this way?

Two reasons, think of non technical person changing a tyre, without the screws
the drum tends to come off with the wheel ! Also it might land on their toe or
roll off down the road - embarassing.

The other reason is brake adjustment, without the screws they would need
manually adjusting each time the wheel is removed - that's also why the drum
only goes on the hub in one position and is centred by the countersink part of
the screws.
