anti-squeal shim to the piston or the caliper?  :-/ The set I'm replacing I've fitted the shim to the piston but they've been squealing like a stuck pig! 

[TheBoy]

piston i thought.

chamferred the leading pad edges? Copperslip (mostly to annoy Gayboy Gixer )?

The new set of TC pads already are. The old set still had some of the original chamfer left but are a little over halfway worn through.

I've got loads of copper slip!

I don't think it makes much odds Andy tbh. Can you pinch the shim off the old pad and stick it on the non shimed pads? Gives shims all round then, they are only stuck on with glue. Double sided tape will do.

And tc pads already have massive shamfers on them, assuming it's tc pads you have?

Doh! It never occured to me to nick the old shims.
They are TC pads.

Got to wipe all that copper slip off now though.  .  .

Carefully appled to where it matters!

I put the rubber backs to the caliper, never bother with shimming it  :-/

the rubber back IS the anti-squeal shim  :-/

So you've changed your mind now.

Is it? What is that thin sheet on the other side then? Or am I thinking of the Rover? Me confuddled now

Certainly, I always put the rubber towards tha caliper, not the piston.

I've got a rubber faced shim on each now. Both rears have a rubber faced shim, but there are two pistons, so maybe the shims should go to the piston.  :-/ :-/

[fiend61]

i thought that the shims went on the backing plate of the pad  :-/

[Andy B]

i thought that the shims went on the backing plate of the pad  :-/

they do  ...... but the question was which one? Inboard pad next to the piston or outboard pad against the caliper?   

[fiend61]

The anti-squeal shims are a direct replacement to some shims that are fitted standard. If you look at the caliper where the sides of the pads rub against the caliper you will see them.
according to that caliper side

It seems that traditionally they are fitted to piston side Andy but can be fitted to all pads if you so wish. Definately on piston side on mine. Big round circle on shim gave me a clue. 

Is this link of any use.
