so this might be the dumbest thing you heard in awhile but here it goes...after noticing pads were getting worn i decided to do all around drilled/slotted rotors,i believe they are powerstop and pads are monroe ceramic. long story short,everything worked great and smooth for about 300 miles,then i parked car behind our barn due to snow and below zero temps for 2 months!..i drive car tonight for 1st time and when i hit the brakes, feels as if rotors are warped,i can even feel it in the steering wheel....now... car rolls and drives fine,could it be minor flat spots in tires due to being frozen to the ground for 2 months and i only notice while braking due to force put on the front tires??..i cant believe the rotors are warped after just sitting?? any input would be appreciated!
** UPDATE**
so after further investigation,i discovered 2"spots" of imbedded rust/scale on each rotor.one on the outside and one on the inside. i removed them and sanded down with 80 grit paper on a da sander and cured the problem. the rears were fine but got a quick buff as well while i was doing it.braking has been restored to a smooth quiet experience. so rotors were not warped and tires are fine,[except for dryrot] but thats another issue..
