Same way as the front. First remove the calipers, then remove the two cross-point screws that hold the caliper in place . finally, remove the rotors and replace.
Changing Disc rotors on a 88 - 97 GMCIt is very simple. All you have to do is remove your tire. Then on the back side of your brake caliper there are two screws you will need a 3/8" Alan wrench or equivalent. After that you can simply pull the caliper off of the rotor and then slide the rotor off. If you do not want to bleed your brakes then you can simple take a 3" C-clamp and tighten the caliper back. This will allow you to put new brakes on your new rotor without bleeding the lines.
To change the brake rotors on a 1991 Honda Civic raise the vehicle. Remove the wheels and brake caliper bracket. Remove the brake pads. Loosen the rotor mounting screws and replace the rotors.
Youll probably have to drill it out and get a new bolt to mount the caliper with.

On some vehicles there is a caliper mounting bracket, on others the caliper screws directly to the steering knuckle.
remove the tire you will see the caliper there are two bolts on the back side usually star sockets remove those and then you can remove the caliper lift it straight up remove the outer pad first no bolts or screws just pull it off then take a 6"-8" c-clamp push in the inner pad so that you don't have to bleed the brake lines then remove the inner pad and reverse the process.

If they are disc brakes only and not bisc and drum brake combination. 1) remove the cap on the brake fluid reservoir 2) After removing the wheels open bleed screws and let the brake fluid pressure out (make sure the reservoir cap stays off during this whole procedure) 3) Them proceed to remove the two mounting bolts on the caliper after that go ahead and remove the caliper 4) once the caliper is removed go ahead and remove the pads and rotor which ever one you intend to change if not both 5) Replace worn rotor and or pads with new ones. Once new pads are installed put brake lube on the brake pins and guides and around the contact area of the dust boot or rubber seal 6) Put caliper mounting bracket back on along with the pads 7) Put caliper back on 8)Once the caliper is mounted go ahead after all the bolts are torqued to pump the brake pedal 3-4 times I usually pump them until stiff hold the brake pedal down and bleed the brakes 9) Once the brakes are bled refill reservoir put the wheels back on and torque them down 150ft. Lbs. should be good and then your done.
