Drilled slotted rotor noise pressing brake pedal?
 

I installed new wheels tires springs rotors calipers and pads
so..a lot of new stuff
The rotors are drilled and slotted bbk akebono size
Everything is beautiful.. Quiet.. Aligned and in perfect working order.
However
I get this unusual sort of noise vibration when braking. It happens from about 40 to 35 mph..
The frequency is like driving over a median strip design to make noise and alert you your out of your Lane.
But it's light and not bad at all. I'm ocd and I can live with it. Just curious what it might be.
It's got to be either the rotors or the tires. I doubt it's the tires.
I've never had drilled and slotted rotors before.
Anyone experience this with these type rotors?

with new rotors & pads did you do bed-in process ?

I did
followed the power stop procedure which is basically 5 moderate stops and 5 aggressive stops.

In my experience, drilled/slotted rotors make noise. It's not usually too bad, just how the holes and slots create some noise as they pass by the brake pads. It can even happen when not using the brakes.
