Re: [DML] Custom Drilled Rotors

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?
