After replacing the pads and rotors breaks are pulsating
Did you replace the front and rear or just the front? Rear brakes can make the pulsation as well. Also if your ABS system is activating that could be described as a "pulsation". The ABS problem is usually caused by a bad wheel speed sensor or ABS module failure. ABS modules can be rebuilt (see ebay BBA-Reman) Wheel speed sensors are available at most auto parts stores. Some Saabs require the replacement of the whole hub assembly.
SOURCE: How to replace the rear break pads in my 1997 Saab
Jack up the car and remove the rear wheels.
Remove the Caliper pins/spring by pushing them toward the inside of the caliper with a drift.
Remove the brake pads by sliding them out.
Push the caliper pistons back in with a large pair of channel lock pliers or a large C-clamp.
Refit in Reverse. Be sure to tighten the Alloy wheels to 86.6 ft lb and if steel wheels then to 67-78 ft lb.

I'm not familiar with Saab
I recomend buying a replacement rotor and looking at it, usuly they eithe are made on the wheel hub, or have two blind holes threaded to put a bolt in it and tighten to pry the rotor away from the hub
Usualy 10 MM bolts an inch long will do it
