My last three BMWs have all had the same idea and I've done all the pad
changes. Not had a problem yet. If the seals are good they shouldn't rust.

Methinks that that's probably the important bit, and copaslip isn't
particularly good for seals, wheras silicone grease is.

Copperslip can be used on pad retaining pins, but should not be used on
caliper slides.

The slides should have a light coating of a grease that won't dry out
(normal greases tends to dry out, and can cause binding brakes), and won't
attack rubber (mineral oil based grease can cause the guide seals to swell,
leading to binding brakes), which makes silicon grease the ideal choice.

They normally do supply a sachet with aftermarket pins.

Any reason for that, moray?
