Ttrs brakes.....noise coming from front

[oak_grun]

Hi. I have had ttrs front calipers fitted using ttrs discs running 12mm spacers.

Thing is at low speed I can hear a rattle coming from them. It's an intermittent metallic sound.

Any one else experienced this?

Any ideas what it could be?

Thanks

Have you fitted dust shields behind the discs?

I know some calipers use anti-rattle clips too. Could be the case with the RS caliper, but I'm yet to get hold of a pair for a proper look!

Are the discs slotted?

Are the discs slotted?

Slotted? What is that? 

They are standard ttrs discs

Grooved...

I had a what I thought was a rattle when I fitted my AKS BBK, came with 370mm slotted/ grooved discs. Bugged me for weeks, I had Alex demented, convinced there was a rattle  until after lots of research, discovered it was air being pushed pass the slots creating a kind of rattle sound.

I don't even notice it now, I just think you're always a bit sensitive to new sounds
