I usually open the bleeder valve and use a large C-Clamp to compress the piston. this allows the fluid to escape and the piston to move easily. trying to force the fluid back up the system can damage a lot of things! especially if you have ABS brakes! The piston should go in easily, if it doesnt, something is wrong. Make sure to bleed the brakes once your done.

acctually i got the drivers side one back in and i had to turn the piston untill it was all the way in. This one i can just keep turning it and it does not go any further. Even the Protege you dont depress the piston with a C-clamp there is an adjuster screew on the back of the caliper you turn untill the piston is back in place. There is no adjuster on the 3. Im not sure were i should go from here though.

Our cars use a ratcheting mechanism for the parking break.... You can NOT just compress them with a C clamp or you WILL break stuff.

You need to apply compression pressure while rotating the piston.

There is a special tool made for this... It grabs onto the 2 indents which you can see on the inside of the piston.

This is just of many products available Link
