If you dont like the C clamp then you can stick screw drivers down between the pads and the rotors and pry them back... which is refered to as the cave man technique....

I change my rotors when they start sticking...I can buy them for about 60 bucks so that is why I change them... You can also rebuild them for about 20.

Yes, Craig I actually believe a guy should have a spare engine and spare transmission and change them out periodically....It gives a guy something to do in his garage over the winter. I will be rebuilding my spare transmission this winter... I am actually thinking about rebuilding my engine just for the heck of it...
