Cross drilled/ slotted Rotros, DO yours make noise Options

[Jeremy1210]

So I did the rear disc swap 2 years ago. I noticed that I would get some clicking and humming noise from my rear D/S and now my rear p/s tires. i figured that it was my wheel bearings, but I took my car to toyota today and said I think my bearing are bad. well they called back and said it wasn't my bearings; those are fine. They aren't sure whats causing the noise. They suggest that its the rotors cause of the air, but Im not sure. I asked them to make sure everything was in working order incase I did something wrong. According to them everytthing is working correctly and nothing is loose....

So now Im at a loss of what could be the problem... does anyone have any ideas what I Can look for/ check? or if you have extra noise from these rotors let me know. Its kinda annoying and loud and I'd like it to go away.

Thanks for the help

i have slotted front rotors and i will hear a "whirring" sound under hard braking caused by the slots gassing a little and the pads being mashed into the slots which shave a little off on each pass. a whirring sound is normal, i'd say that clicking isnt.

this clicks sound from the front is it? does it only happen under gentle braking but then go away if you brake hard?
