2001 Toyota Camry Vibration when braking

You didn't say if the rotors were replaced during the brake job. If they were, it is very common for new rotors to warp after installation. Machining them will take care of the pulsation.

One of the most common causes of warped rotors is uneven tightening of the lug nuts. It is critical that a click-type torque wrench be used when tightening the nuts, otherwise uneven clamping forces and heating and cooling cycles will cause the rotors to warp again. The other clue that the nuts weren't properly torqued is the broken or stripped studs. Over-tightening of the nuts shows up the next time someone tries to remove them.

Alignment problems cause tire wear, pulling to one side, and / or a crooked steering wheel. They rarely result in a shimmy.
