Brake upgrade?

Hi, I have a 2007(i think) specialized hardrock pro i bought few years back and never had chance to use it but now am getting back on my bike.
It has Alivio cable disc brakes but they are rubbish.
Are these generally naff brakes or does my bike just need a good service.
Im interested in upgrading can i fit hydraulic disc brakes easy enough?
I dont want to spend alot so am interested in picking up a s/hand bargain what do i need to make sure i have so everything will fit ok?
thanks
sam

there were some bands available to allow some of the shimano shifters to be mounted after splitting but they are rare now. and may cost as much as new shifters.
your other option is some Avid BB7 calipers. Best Cable calipers out there.

Nick meant WHICH shimano shifters, they make dozen (hundreds)
