I am searching for those little metal plates that go between the pads and pistons. What do they exactly do? My Haynes say they are piston seal retainers but I always thought they were some kind of anti vibration device.
Anyone know were to get some new ones?
Do they really need to be there?

I always thought they were called "anti rattle plates",
but you can see that they stop the piston spinning inside the caliper body.
I have seen them in some rebuild kits,(ATE) but not all.
Second hand may be your only option.

Those rebuild kits are like $80 I think. Probably not worth it just for those plate thingo's. The ones I am using are holding together by a thread and was wondering about throwing them all together. I have seen that most disc conversion kits dont come supplied with them so I am just wondering how important they are. I guess they would be pretty important if they originally came fitted.

Brad, are your calipers twin or single pin?

I think there's 2 different retainers
theyre not that critical, i went for about 5 years without having any in

they are twin ate calipers Joel. At some time in their life somone must of put them in foul cause they look bent in a way that does not look like they should be bent. Like not a flush fit. the tabs ends are bent around the piston and thats where they cracked . Maybe they are the wrong ones. I will post a pic of them.
cheers.

Yeah - they're anti vibration plates, or anti squeal plates.

The idea is meant to be that they put a very slight amount of pressure on the pad even when the piston is back... stops the pad vibrating between piston and rotor basically. Some pads don't use 'em at all, and instead have a self adhesive rubber pad on the back... EBC Green's for example I know are like that.

Like Joel says - fine to leave 'em out if you can put up with the odd bit of squeal
