98 accord rear brake caliper

Hi,

Having replaced my 98 accord's front brakes earlier, I tried to replace
the rear brake pads. To my astonishment, the caliper was so tight that
even after removing the two caliper bolts, the caliper would not come
out of the caliper stand, it is tightly fixed to the pads / rotor. Did
anyone have a simliar situation ? Do we need to push the pads towards
the rotor with a C-Clamp to get the caliper out ?

Also I noticed that in the Haynes manual, there is a different way to
push the piston, they say to rotate the caliper piston instead of just
pushing it back with a C-Clamp, is there a difference between the front
and rear disk brakes ?

Any ideas, appreciated ..
