I have installed my rear msp rotors and pads before but i'm still new to fixing a car and wanting to learn. I decided to take it up a notch and rebuild my front calipers (mazda6 BBK) since i will be putting new rotors and pads on while i'm at it.I also do have a spiral piston brake kit so it is done properly. Now taking it off i'm assuming it's like the rears when i have it apart and take the piston out of the bore is there a thread or a special way i have to put it back in other then lubing it?
