uhhhhhhhh ... you might not want to be floor-boarding the rebuilt. it should
be treated just like a brand-new engine, and lots of folks say it should be
somewhat 'babied' for about 1000 miles or so. but do vary the speed on the
highway (don't sit on cruise control at 55) ... it supposedly helps seat the
rings and such.  but it shouldn't be bursting like that. that sounds more
like something electrical or air-related not being hooked up right. ??

it could be an uneven rotor. but it should give a 'pulsing' sensation, not
just a vibration. depending on the miles on the car, you could have a worn
rotor (depends on the quality of those  'aftermarket' ones) or just a worn
brake pad that is vibrating (cause it's not pressed hard against the rotor).
you need to check it out, though.
