Unlike domestic cars, imports don't need all that BS hardware (I've always hated all that stuff) and you won't need any hardware whatsoever with your Volvo, just pads and rotors. The rear e-brake shoes must be de-adjusted to remove rear rotors w/o bending the clips. There's a hole in the hub area of the rotor so using a flashlight, you'll be able to see the star wheel. Then re-adjust with the new rotor. I'm sure the e-brake shoes will still be fine.
