so when i stop i get this jerking feeling but not in the pedal. like an out of round rotor but the pedal does not throb. i jacked it up one side at a time and ran i up to speed then applied brake with no noticeable jerking. i know that the rotors and pads had been recently replace when i got it.

Sounds like it was setting a while and rusted the rotors under the pads. Leaves a spot that will grab as you brake. Easy solution it to pull the front rotors and turn them. (the fronts are more likely to be felt than the rears).

i did pull wheel on one side to look at rotor and all looked fine. i did put a lot of miles since purchase i do not remember any big issue with braking right after purchase, but yes it had been sitting at least six months. rear drums look original. i also notice i have a wheel bearing going bad not sure if front or rear. wondering if its rear it would make brake wear/grab funny?

Bad bearing could do it, brake pressure would try to "straighten" the drum/disc and grab as it moves.
