Begin by lifting the rear of the vehicle and secure it using jackstands, use blocks on both front wheels to keep the vehicle from rolling, the parking brake can't be applied, if it is you won't be able to remove the rear brake rotors, leave the vehicle in neutral also.
Once the wheels have been removed from the vehicle use a punch to drive out the the brake pad safety pin.
Pull the pin all the way out as shown in the picture, remove the anti rattle clip.
Note: If you press the anti rattle clip in, it will be easier to slide the pin out.
Remove the rear brake pads by pulling them straight out.
NOTE: The vehicle we are working on doesn't have a brake pad wear sensor, if yours is equipped with them, detach the sensors prior to pulling the brake pads out.
If you don't have access to a caliper piston spreader you can use a flat screwdriver as shown in the image, take note that to avoid the old brake fluid to travel back in to the system while compressing the pistons it will be necessary to attach a hose to the caliper bleeder, the hose will need to be attached to a container, crack the bleeder open and compress the pistons, make sure that the container is sitting higher than the caliper while you do this to avoid air from entering the system, once the pistons have been compressed all the way in proceed to close the bleeder screw and remove the hose.
Remove the two caliper mounting bolts, pull the caliper away from the knuckle, sit it on a stool with the brake hose still connected, make sure that the caliper is not pulling on the brake hose.
Remove the allen head screw shown in the image.
To be able to slide the rear brake rotor out, it will be necessary to adjust the parking brake shoes in, we are showing you this procedure with the brake rotor removed so you can see where the adjuster is located ( rear upper side) the picture shown is the right rear wheel.
Slightly turn the rotor till one of the wheel bolt holes is aligned with the opening on the hub, insert a flat screwdriver and proceed to adjust the parking brake.
Right rear wheel: push on screwdriver handle up to loosen the brake shoes.
Left rear wheel: Push screwdriver handle down.
NOTE: You will know if you turned the adjusting screw in the wrong direction because the rotor won't turn and the adjusting screw will be harder to turn.
Once the old brake rotor has been removed, clean the parking brake shoes using brake cleaner.
