How do you depress rear caliper on a 2004 Ford Freestar?

Answer 1

---- You have to turn it (caliper piston) as you are depressing the piston back into the caliper. You can't just "jam" it in. I used a caliper tool (for depressing the caliper) and turned the piston with large jaw pliers. This gives both inward pressure and the turning motion. I turned it clockwise and that seemed to work. There is a special tool you can buy to turn the piston as you push it back into the body of the caliper but if you work carefully and you are VERY aware of the rubber boot (don't rip it) then pliers are ok (don't tell the Ford dealer). Cover the pliers with something so you don't scratch/ruin the piston. The front brakes are just a standard push - don't need to turn them. Why do the back brakes work this way? Has to do with the parking brake. If you look you can see that it is attached to the caliper on the rear.
