Disc warping?

If it was not the ABS, the vibration is most likely caused by pad deposits on the rotor surface. The mistake that most people make is to bring the car to a complete stop when they have been using the brakes allot and the rotors are really hot. At those temperatures the pad material will bond to the rotor surface and create a ridge.

When you have been hard on your breaks you should always let them cool before stopping or parking your car. At a stop light, keep your distance and slowly creep forward to keep things moving to distribute the heat.

Properly bedding your pads from the start also helps to prevent deposits. This gets things up to temperature and burns off the coatings to allow the two surfaces to work together better.

If your vibration is really bad and does not go away in a week or two of normal driving, you could switch to a more aggressive pad for a week and that should smooth things out.
