weird stuff? brakes maybe??

[Team Rootbeer]

just did a 5 lug swap.....got new cross drilled/slotted rotors, pbr bads, new fliud......all the stops.....and now, when i engage the brakes the rear shakes really bad when i engage the brakes like the rotors are warped horribly or theyre grabbing or something???? it shakes the whole rear bad what could it be>???? are the pads just not broken in yet?

sounds to me like you warped the rotors. Did you seat the pads in gently? If you heat the brakes up the first time that you drive on them the new rotors will warp easily. Also if you resurface the rotors and then go out and hammer on them they can warp.
