OK, i have clunking once again!! on the front brakes.

Having taken the wheel off and inspecting the disc, hub, caliper etc..... There is about a mm gap each side of the hole in the disc where the studs come through, thus enabling you to be able to move the hub ( by pushing the studs ) about a mm before coming into contact with the disc.... i was wondering if this is what is causing the clunking... or is this normal?

thanks gents

doesnt sound quite right to me.....

Colin.......where are you ?

More likely to be the pads moving in the caliper bracket.
Lexus have issued a tech bulletin to their dealers about it.

is it when you brake,, may be the pads moving.. copper slip sorts the noise out..

Have a look here. Not for the IS but the same problem and cure.

Thanks, so should i take it that this little mm gap is normal??

I think the gap is normal.

Hi Scott,

Yes that little gap is perfectly normal, the clunk sound that u are hearing is the pads touching the caliper framework - put a tiny bit of copper or ceramic grease on the end tangs of the pads and the noise will stop.
