I have done disc brakes before they are easy, I just want to know if I need that brake kit from the Nissan dealer or not. I have shims and pads, what comes in that kit? Also, the rear pistons have to be rotated when pushing the piston in, my haynes manual says that needle nose pliers can be used to turn the piston. Anyone have success with this method?

 

Just get a tool from your local auto parts store.
it attatches to a rachet wrench and it pushes the rear pistons in safely.
Nose pliers can be a pain in the A$$
Good luck
