Thinner backing plates on disc brake pads? No room in caliper for rotor with SRAM pad

[biner]

Hello,

I know this is a little obscure, but does anyone know if there are disc brake pads with thinner backing plates than others?

I have SRAM HRD ('17) caliper. When I put new SRAM "quiet" pads in the caliper, there is not enough room for the rotor.

The pistons are in good shape and retract fully (i.e. they are flush or even inset on both sides of the caliper). The only thing taking up space within the caliper is the pads themselves. In the past I have sanded the pad, but that seems a little ridiculous to me.

Is it possible that some pads have thicker backing plates? If so, maybe I can find an aftermarket pad with a slightly thinner backing plate to help fix this problem.

Just to eliminate some possibilities: this happens with a fresh bleed, air bubbles cleared, reset pistons, etc. In fact, this happens even with the pistons fully removed from the caliper! ( I did that once just to see).

Thanks for any ideas.

I've never heard of this being an issue. Never. I've got nothin for ya.

I suggest filing the pad's, hold them in a vice. Lot's better than sand'in!

Please...enough w/ the apostrophe abuse. And don't sand/file your pads. Fix the actual problem rather than the symptom.

ETA: I know they say 'quiet' in the description but they're commonly known as 'organic'. The 'power' pad is commonly known as 'metallic'. The backing plates on all are the same whether they're aluminum or steel. They're all 2.1-2.2mm.
