Hello Rodrigo, Thank you for the question - the rotor removal is a simple job on the Seville. I will give you the complete procedure. Raise and support the vehicle.Remove the rear tires, unbolt the caliper from the bracket, unbolt the bracket from the spindle and clean and grease all slide plates and slide pins using synthetic caliper grease insuring the new brake pads will slide properly in the clean slide plates, remove old rotors from hub assembly, clean machining oil from braking surfaces of new rotors and install them on the hub assembly, reinstall both brackets on spindles and tighten bolts, using a "c" clamp press the piston back inside both calipers and reinstall both calipers on both brackets and tighten bolts, reinstall tires... torque all lug nuts to 100 ft lbs and place
vehicle back on pavement. DO NOT DRIVE VEHICLE. sit in drivers seat and press the brake pedal to the floor several times until the brake pedal feels secure under your foot you are now ready to drive... happy motoring
If the rotor is stuck, smack it with a dead blow, or soft faced hammer--- it will free up
After it is loose, pull it straight off of the wheel studs.
