Official Honda brake pads normally come with that thin layer of perforated metal on the back of the pad as shown in the photo below.

The EBC brake pads I purchased recently do not come with this. Does it matter? Why do some pads have it and some do not?

The last time I got EBC HH pads for a bike they had those on.

I recently got some EBC pads for a car and they say the don’t need shims.

Could be a different pad material I guess.

Some pads do, some don’t.

I wouldn’t be too fussed about it.

If there's a problem, you can buy stick on anti-squeal pads from EBC.

Heavens forbid !

Using a little copper grease on the back of the pads and where they sit in the caliper, what are people thinking...

... does this anti squeal shim not fit on your new EBC pads?

If not, in moderation, I would apply a thin smear of copper grease to the backs of pads, ive always done this without issue so far. ,,and of course caliper pins etc.

Was told I must by do this only recently by Denis Trollope or my (EBC green stuff) pads will squeal like a b'std with my new AP calipers....

I was thinking of removing the shim from my old Honda pads. Not sure if that will work or not though. I'm planning to fit the new pads at the weekend.

Who the fk is Denis Trollope?

Coincidentally I’ve recently fitted green stuff pads with no shims and no grease. Not a peep of a squeal from them.

The only thing I would be greasing near brakes is slider pins that are contained in boots and then with silicone grease and not copper.

Denis Trollope is well recognised throughout the world as being a motorbike maintenance goddess. There's pretty much nothing she can't fix.

I don't use any grease unless the manufacturer guidance says to do so. On cars I use it mostly to keep the shims in place as they can have quite complicated arrangements.

I wouldn't use "copper grease" at all, I use "ceramic grease". I believe there's good reasons to not use copper grease, but the only reason I personally avoid copper grease is because it's messy as fk and I always end up with copper deposits on my clothes.

I use "red-rubber grease" on the pins and anything which touches rubber boots. I've heard the petroleum base of most greases degrades the rubber. Anecdotally it certainly seems true. It's certainly what I use to rebuild calipers.

I do enjoy my grease selection....

You need to add silicone grease to your selection as red rubber has pretty much zero heat resistance which is useless around brakes.

I fitted both the front and rear pads this afternoon.

I transferred the metal shims from the old rear pads to the new ones. I was planning to do the same with the front pads except when I took the old pads out, only one pad featured the metal shim. This seemed odd and may have explained the fact that one of the pads was noticeably more worn than the other. Therefore, i just fitted the new front pads without the shims.

If the front pads start squealing while the back ones don't then it may suggest the shims are quite useful. I'll see how it goes as the pads bed in.
