Acura CL rear disc brakes

Ok, I've mainly stuck to domestic vehicles when it came to side-job service, but I received a job to do a brake job on a 99 Acura with rear discs. Now on the domestic vehicles with rear discs, I used a special tool to actually screw the piston back into the caliper. Is the Acura rear caliper the same way, or does it need to be pushed in with a C-Clamp. Also, if it is threaded, I assume I turn it to the right to thread it back into the caliper. Any help without discrimination would be appreciated greatly.
