You need a good 3/8 inch drive socket set metric. You will need a c-clamp to compress the piston. I think you will need a T-50 torx bit but I may be thinking of a GM vehicle. Turn the wheel all the way and take a quick look before you start. You will need a screwdriver also. Are you going to take the rotors to get turned. You will need a channel lock, pliers to remove cotter pin.
Call for prices to turn rotor before taking them in. An independent shop is the best places that sell rotors always try to sell you new ones. I have my own mikes and check them because not all employees can read them.
