No I haven't lost anyones vibrator under my front seat. and no I'm not sitting on my phone. I have a week till I go back to school and this is kinda concerning. anyone know what I have going on?
Pulsing vibrations with foot on break in drive

How exactly did you bed the pads. If you did repetitive hard braking did you come to a complete stop or let it keep moving. If you came to a complete stop you could already have a build up on the rotors. When bedding pads you should avoid complete stops until the rotors have cooled.
Instructions for bedding in your brakes
Just re-read the title of the thread. I read it as it was referring to breaking in/bedding the pads during a drive, not while the it is in drive the brakes pulse. My response is likely irrelevant.

So how big of a deal is this & how do I fix it

Warped rotors would be my #1 guess. Maybe something with the ABS system as well.

Warped rotors would first on the list... People overlook the rear drums too... If you run a tight adjustment they can vibrate the vehicle pretty good if they are warped
Now are you saying its vibrating in drive without the vehicle moving? If so then I'd check for broken motor/ trans mount and check the exhaust as well

oh yeah I forgot, I got my rotors turned about a month ago and yes this is happening while I'm stopped
I would suggest trying the break in process a time or two. I doubt you warped a rotor that quickly unless you got it extremely hot and cooled quickly. Keep in mind for the break in process you need to get that rotor hot. Litterally you will be smoking the brakes and have brake fade. Upside, re-bedding the rotors/pads is free. Worst, you pull the rotors and have them checked. As mentioned previously, if you came to a complete stop during bedding before the rotors cooled you likely built up film on the rotors and pads. Follow the process on the link and i think you will be fine. Key is doing it in an area where you can drive for a bit til the rotors cool. I had to use my ebrake on back roads to keep from stopping completely w/foot pedal.

I haven't done brakes on my Runner yet, but when doing the brakes on my Trans am, like a dumbass, I didn't replace or oil the slave pins, because they looked good to me and I was in a hurry. Upon assembly, I didn't notice that one of the calipers was hung up. It took about 2 miles and a large puddle before one of my brand new rotors was warped. Not saying this is your problem, but I concur with what others are saying about checking the rotors. Of course...this is all based on if the vehicle is moving when you feel the "vibration".

It's almost like a shutter, you can feel it in the floor board. it's not everytime i stop and have my foot on the break. it's hard to describe, I'm sorry, I'm being as descriptive as possible
JPB - I think I have the same issue. See if this is what is happening to you:
Car is stopped but engine is running. Idles fine, no racing or surging. Engine sounds fine, no knocking or other cause for concern. But, every 5-10 seconds or so there is a slight vibration (or shudder as you described it) that can be felt through the floor (if not wearing shoes) and in the steering wheel (at least for me). Note - this is NOT the wheel shimmy/shudder one feels when applying warped break rotors, nor is it the high-speed wobble that seems to be a fairly common problem. This is very subtle, like you have to pay attention to notice it.
Is that accurate? My guess is a faulty motor or transmission mount. After 15+ years, those have to be nearing the end of their natural life span and I know I have never replaced mine. I'll likely be replacing these later this year (after redoing the rack, bushings, and inner tie rod ends) but if you, or anyone else, gets to it sooner, please let us know whether that solved your vibe problem.
