Changing the rotor and brakes on my '03 Taurus and the front caliper piston will not compress. At first, I couldn't figure it out. I took the cap off of the reservoir to relieve pressure, that didn't work. I removed the bleeder screw, that didn't work. I took the piston out of the caliper bore and about a cup of brake fluid came out. I tried re-seating the piston in the bore and compressing it, but to no avail. I have greased up the piston and the bore, nothing happening there either. I finally removed the whole assembly and now have it sitting on my workshop table. Compressing still doesn't work and I am making sure the piston is going in straight. I have checked the seal as well and that is fine.

Using a 6"C-Clamp with an old brake pad.

was able to solve the issue by lightly tapping with a small rubber mallet around the center of the piston

Glad you solved it. Thanks for the update.
