I've been following this method on changing my brake pads on previous cars and have never had any problems. This is what I do:

Take off wheels.
Remove calipers by loosening the two bolts.
Take off pads and grease new ones and place them back on to the braket.
Open master cylinder resevoir.
Use a C-clamp and slowly push the pistions back in.
Bolt calipers back on.
Mount wheels and tighten lug nuts.

I followed this when doing the front brake job on my 98 gs4. Ever since then I been having very low brake pressure. The pedal is very mushy and will slowly sink to the floor if it's kept depressed. The braking power is weak and I can definitely tell that it's taking much longer to stop. The system has been flushed twice by a machine at a shop. The last flush, the mechanic told me that when the brake system was hooked up to the machine, there was fluid going to all four corners but once it came off the machine, fluid somehow wasn't going to the rear calipers. So basically the front is doing all the braking. Did I somehow damaged the master cylinder when I pushed the caliper pistons back in with the clamp? That's the only thing I could really think of because I already replaced both front rotors, both front calipers with brand new pads.

I'll be taking the car in to the dealer later today. Crossing my fingers that it's not the MC/ABS system. I wouldn't know where I'm going to cough up $2000 for it.

I did the exact same thing when I replaced my pads today and now I have that mushy feeling...what can this be?

i did the same thing and i havent had any problems. did you try to bleed your brakes? if i remember correctly, the car needs to be on the on position when bleeding.
