I offered to show my son how to replace the brake pads on his 2013 Ford Focus that has the rear disc brake option.
After i rented the Universal kit from Autozone i was surprised that none of the several caliper piston adapters would fit the Fords caliper piston holes to retract the piston back into the caliper.
So, i bought this tool and it worked as promised.
I attached the tool to my Milwaukee drill/driver and set it to low speed and pressed/rotated the piston back into the caliper.
I recommend this tool.
Worked for me on the 2013 Focus rear brake calipers.
