I just installed Stillen Crossdrilled front rotors with their metal matirx pads. Just 10 mile son the new stuff so I can't comment on how well they stop, but I'm getting a low frequency whinning when I stop. I assumed that it was from the cross drilling?

Anyone else experience this? Is it normal?

 

yes I have the some noise, make sure that your easy on the brakes for about 3 days or so to break them in correctly.Also when you get them realy hot thay get grabby, but once they cool thay change back. That scared me when it 1st happened
