Hi all.

Bentley calls it a "Damping Plate", VAGCAT diagram (like ETKA)
shows it as an "anti twist retainer". Image:

I've never seen a Girling caliper up close but the diagram
appears to show a similar piston type for each.

Without the OEM plate, is the caliper piston prone to rotating?

This may be a moot question. The pads I had in my 1981 Westy had a soft
backing material. Image showing back of one pad: http://tinyurl.com/p9egeyz
I assume this is an anti squeal material but is it also
there to keep the piston from rotating?
Pads had at least 75% wear left, I don't know how many miles,
but it doesn't look like the caliper piston rotated.

Thanks,

Neil.
