Can disc pads just fall apart

was doing some mainetenance on bike the weekend and took pads out to clean and when i went to put back they fell apart lol
so i put the old ones in i got when bought the brakes (got them second hand) and the pad seemed to be quite a bit thicker than the new ones that i have put in. Ive done bout 600 miles on these pads but not off road just commuting and fitness, should they last longer??
the problem now i have though is the other pad that was in there (new one) has also broke now so on my ride home had a horrible grinding as the disc was rubbing on metal. is it a case of new discs or have a ballsed up my breaks??
another thing is the psitons seem to be quite close together and even when the barrel adjuster is turned to its loosest there is little gap. is it a case of pushing the pistons back in with a tyre lever or summin? have i pressed the breaks by accident when the wheel was out? if so how do i sort this out
would it be worth swopping the padds from my front discs to the rear, and putting the old ones on the front as the pistons seem further apart on the front
when i say pistons im on about the bit inside the caliper that compress to take pads nearer disc, not sure if im using the right terms
they are giant mph brakes
also wheres the best and cheapest place to get pads
thanks

yes pads can fall to pieces.
you need to adjust the pistons.
How depends on the brakes and will be in their manual."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Alright nick, thanks for reply
could it be a case i need to bleed the brakes aswell as not sure if i pressed the levers when wheel was out. if i pull the brakes the pistons seem to bite the disc enough to stop it, just horrible grinding noise where disc is rubbing caliper.
when i was cleaning bike was using muc off spray which does say is safe on discs etc but not sure if i got a bit on the discs, would this also add to the grinding?0 -
on the MPH you should be able to turn the pad adjuster to move the pistons.
grinding is normally dirt."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

yea i can turn the pad adjuster but even when it is turned to its extremes its either too tight on the disc and wheel doesnt spin at all or the lever is so loose it doesnt give any stopping power and just touches the handlebar grips. Think rotors are a little bent as its not constant grinding, just intermittent. might switch pads out of front caliper and see if they are any better, then i will know if its the pads or the pistons or would that just not work??0
