How to properly replace a brake disc on Mazda Protege?

Relax the wheel lug nuts, elevate the car and hold it firmly on jackstands. Take off the wheel and place in the lug nuts to secure the disc to be firmly seated perhaps with some washers to make it fit. Take off the brake caliper and leave the brake hose attached and hang it out of the way using a piece of wire; make sure it is not suspended on the brake hose only. Look at the disc face with naked eyes to identify marks of scores and damage; a shallow groove with light scratches and 0.039-inch deep are normal; however, deep scoring, more than 0.039-inch, needs to be refinished. Test the disc on both sides of the disc because of the extreme wear. In checking disc run out you should insert a dial indicator of about 1/2-inch of the outer edge, position it to zero and turn the disc in slow movements, not letting the reading reach the allowable limit; the disc should be resurfaced anyway to remove the brake pedal pulsation. Make sure that the disc is not machined less than the recommended minimum thickness which is inspectable using a micrometer. Divest the lug nuts that are holding the disc and remove the disc off the hub. With the models with ABS, disconnect the speed sensor connector, remove clips that hold the hydraulic brake line, and remove a sensor. Install the caliper and crimp the caliper bolts to the required torque by placing the new disc on top of the wheel studs and placing the caliper. Install the ABS wheel sensor removed (with due clearance to the toothed rotor). Install the wheel, lower the vehicle, and screw in the lug nuts to the required torque. Test the supply of brake fluid and fill it up where needed and press the brake pedal a couple of times before driving to confirm the right functioning of the brake pads and disc.
