If you can't compress the piston with a C clamp back in to position to fit the new brake pads I would suggest replacing the caliper completely.
To change the front brakes on a 2000 Ford Explorer, start by lifting the vehicle and securing it on jack stands. Remove the front wheel and then take off the caliper by unscrewing the caliper bolts. Slide the caliper off the brake rotor and remove the old brake pads. Install the new pads, reattach the caliper, and then replace the wheel. Finally, pump the brake pedal a few times to ensure proper pad seating before lowering the vehicle.
To change the brake calipers on a 1999 Ford Explorer, start by safely lifting the vehicle and removing the wheel. Disconnect the brake line from the old caliper, and remove the caliper bolts to take the old caliper off. Install the new caliper by securing it with the bolts and reconnecting the brake line, ensuring there are no leaks. Finally, bleed the brakes to remove any air from the system before reattaching the wheel and lowering the vehicle.
