David: Can you describe what you mean by higher noise level? and when? when braking? I purchased a set of John Hervey's cross drilled and I have noticed almost like a whining or a slight grinding noise when braking (PADS ARE NEW ALL AROUND) I noticed the new noise after the rotors but didn't realize that it could be coming from that. Is that the likely cause of the new noise? Rodney 3300 On 6/17/05, David Teitelbaum <jtrealty@xxxxxxxxxxx> wrote: > You don't mention how noisy it is.
