Re: Brake Knocking
I take it this is just started and that no work on the brakes or suspension has been carried out recently?
Check for obvious loose mounting bolts, etc. The suspension arm bolts can come loose, although Alfa only claim this is a problems with some earlier GTAs.
Check the pads aren't moving in the calipers. There are some OEM pads that are slightly smaller than the originals. You haven't lost the tensioning spring from the side of the caliper have you?
