Ian,
My S4 definitely has washers under the bolt heads, which are then lockwired.
My rear brakes were squealing very badly, to the point of embarrassment. I have recently, just last week in fact, had some shims laser cut out of .55mm stainless steel. These have totally eliminated the squealing.
Some other, Lotus Club Queensland, Elan owners report no undue noise from their rear brakes. I suspect it has a lot to do with the type of friction material used. My rear pads are still original.
I got the dimensions for the shims from the vintagetechnologygarage (Yahoo) website. Look under files for the drawing.
