Though an out-of-round tire could cause the brake pulsations you refer to,
I'd guess it was a warped brake disc.  The wheel nuts (or bolts, whichever)
were probably tightened by an air wrench when the wheels were put back on
the car, and improper torquing of the nuts can warp the brake disc.
You can find out if this is the case with a torque wrench, but the discs
may still need machining when the nut torque is corrected.
