do i need to remove caliper piston?

[zactastic1]

I'd appreciate your input...

first photo is my front caliper... you can see half of the boot was coming off when i took the brake pads off.
Should i :
1. try to push it in with a smooth flat head or popsicle stick ?? (the other caliper had a small area i was able to push in but this is WORSE)
or
2. take the caliper out and reassemble? ( really dont want to do this but might have to?)

here is a photo from the links below, they took the piston out which you can then slide the lip of the caliper boot in easier

You should rebuild the caliper with a new seal and boot. Watch YouTube vids there are plenty of guides.

The kits are cheap. You can try to push it back in, but it won't stay.

Just get a rebuild kit and rebuild them all.
