Friction material has come away from backing plate

IMHO you are being generous!

Not uncommon unfortunately and yes it's a failure of the adhesive. Not all pads are riveted, many are just glued. Should be fine but not always it appears

I hope you're taking the piss about the double sided tape OP, for the love of god do not drive it like that.

If the friction material falls out and disappears into a puff of dust it'll leave you a good 4 or 5 full pumps of the brake pedal away from any significant stopping ability.

I don't think any UK manufacturer has ever made riveted pads in any quantity, if at all. All, with a very few exceptions in the early days, have been integrally moulded. Riveting is, or was, very much an American thing.

The reason I made my comment that it looks as though there are no spigot holes in the backplates is that normal practice is that there are several holes around 10mm diameter in the backplate into which friction material flows during the moulding operation, thus forming spigots which would keep the material in place in the event of adhesive failure. I suspect that in the OP's photos they are just hidden, by the friction material on one side & by the shim on the other - I'd like to see a photo of one of the backplates without the friction material.

Ironically, a couple of years ago EBC announced a new process which would eliminate such failures by forming little "hooks" on the backplate which would hold the friction material firmly in place.

Simple, ask a mate to drive you down to the shops.
