Answer
Dan,

If you did not have the vibration and pulsing brake pedal before the brake jobs, then the shop has done something wrong.

Unfortunately, I cannot tell you for certain what the problem could be.  I have no vehicles with ABS and I have no experience with ABS systems.  Other possibilities include:  Incorrect or incorrectly machined rotors, faulty wheel bearing adjustment (if applicable), or even wheel weights that were accidentally knocked off the wheel(s) when work was done on the vehicle.

You probably should have another shop evaluate the problem for you.
