Fitting Shims

[Benny06]

I upgraded to Brembo HC's and DS2500's late last year. They were squealing slightly so I fiddled about with them which only made it worse.

I filed the ends (several times) and the pads have just about the right amount of play in the carrier. Copper grease also didn't seem to do much. I didn't bother me after a while as I could barely hear it with music and windows up.

However today I had a window down and it is quite bad! But only under light braking, under heavy braking it's fine.

I know it's not advised however as a last resort I'm going to refit the shims to see if it makes any difference. I've cleaned them up a bit and corrected a few slight bends from where I pulled them off last time.

Do they need to be stuck on to the pads? if so which adhesive should I be using?
My memory around the caliper isn't too good! My logic tells me that as the shims are a 'U' shape (on it's side) that the 'open end' of the 'U' will be pointing towards the back of the car as opposed to the front as this seems to be the only way for them to actually fit.

Any other tips are welcome.

Thanks.

Just reading through other threads here the shims go on to the pads not the carrier right? Appologies for a daft question.

Seems I was a bit confused as to what shims actually were.

Not these bits as I now know!

What are these and are they important?

They are anti rattle shims.

try copper grease, and have you bedded in your pads properly, my redstuff took 2 weeks to bed in

Ahh okay thanks.

yes, I've had these pads & discs since August.

I'm being told elsewhere that some copper grease between the back of the pad and the shim is all that's necessary? In that they don't need sticking to the pad. They have raised notches that would stop them dropping down and cutting in to the hub.

you changed front and rear pads? you dont need much grease at all, just where metal meets metal except the friction material itself!
