2005 Ford Freestyle How do I compress calapers

To compress the caliper you can use a disk brake piston compression tool from your local auto parts store (around 10 bucks). You can also use a pair of channel locks to squeeze the brake piston in, however if you try this make sure you have an old brake pad or piece of metal that can be put over the brake piston to ensure it does not get damaged. What you are trying to accomplish pushing the piston into the caliper assembly. Also if you open the brake bleeder while trying to compress the piston it will make it much easier to collapse.
