Hi,the fronts can be pushed back,but the rears have a thread and need rewinding.I didn't have a rewind tool to do the rears,just made do with gently pressing the piston and turning it with pump pliers,eventually it will catch on the threaded part and retract as you turn the piston!A rewind tool would have been easier and quicker,but is not strictly essential.A word of caution,do not try to force the rear caliper piston back as it will scrap the caliper!!
A bit of wd40 or similar and a bit of cleaning of the dust cover stops it twisting and breaking as you turn the piston.
Hope that helps,a little.
