It's pretty common for rotors to seize up on the hub. Spray the middle hole of the rotor/hub with penetrating oil (WD 40, etc.) and spray inside the lug holes. You may want to do this a few times and let the oil soak in. Take a large rubber mallet or dead blow hammer and hit around the perimeter of the rotor. This should loosen it up. Clean all brake areas with spray brake cleaner after, including the lugs. They should not have lubricant on them.
Hope this helps, if so Please rate. Thanks and Good Luck...

Brake rotor and front or rear?

Okay, remove the wheel then remove the brake caliper and move to side do not allow to hang on the brake hose, use a hook to hang off spring or set aside. next remove the caliper bracket, two bolts at rear of bracket to remove it.
next you will use a hammer to remove the rotor.

NOTE: the way the brake rotor was designed was a bad one the hub in which the rotor slides over and the wheel studs slide into holes on the rotor is bad the hub diameter is almost the same size as the diameter of the seat of the rotor that slide over the hub and what happens is sometimes the rust build up on the rotor seat locks the brake rotor on the hub. i do not know if you are reusing the rotors or replacing them, no sure what job you are doing . the rotors to take off you will need to tap on the rear of them with a little force and turn, hit and turn. you will need to see if they break free or if hard beating and spraying into the rear of them is needed with wd40.
Alot of these rotors also have two threaded hole on the face of the rotor near the studs so that you can screw two bolts into holes to help pull them. use wire to tie caliper up and also use a c-clamp to push piston into calipe to remove caliper if needed, Do not remove brake hose, there is no need to open system, here is a picture of the rotor coming of the hub, also there may be clips on the stud holding rotor on remove them use cutters or pry off do not need to reuse , they are to help in holding the rotor on during asm, if you want you can buy them and reinstall them but never reuse them.12_25_2012_5_41_09_pm.png

How to remove brake rotors on a 1996 ford explorer


How to replace the rear brake pads on a 1995 through 2001 Ford Explorer The system utilizes a drum-in-hat type rear brake rotor. The integral drum allows the use of a drum-and-shoe type parking brake system. All other components are similar to their front disc brake components Remove the two bolts on either side of the brake hose with the rubber boots. Do not remove the four bolts where the axle ties in. The two bolts to be removed require a 10mm socket/wrench. Loosen the pads from the caliper Rotor Removal In order to take the rotors off (replace with new or have them machined), it is best to loosen the emergency brake shoes. To do this, behind the rotors, in the back there is a rubber plug, remove that and you can use a screw driver to engage the teeth of the adjusting screw, turn it clockwise to loosen, usually 10-20 teeth. Usually this means turn it downward. After this, it may still be difficult to get the rotors off without tapping them. Use a rubber mallet and hit them from behind. Before really whacking the rotor, make sure you have loosened the adjusting screw enough. It may take heavy swings of the rubber hammer to do this. It will eventually break loose. Parking Brake You might want to check the parking brake while you are here. To remove:
  • Remove the rear disc brake rotor.
  • Remove the outboard return spring.
  • Remove the adjusting screw spring.
  • Remove the rear brake shoe hold-down spring and pin.
  • Remove the brake shoe adjusting screw and nut.
  • Remove the front brake shoe hold-down spring and pin.
  • Remove both parking brake shoes and the inboard return spring.
  • Check the parking brake lever for excessive wear and replace as necessary.
To install:
  • Position the front parking brake shoe to the backing plate and install the hold-down pin and spring.
  • Install the rear parking brake shoe with the inboard return spring.
  • Position the brake shoe adjuster screw and nut on the shoes and install the rear shoe hold-down pin and spring.
  • Install the brake shoe adjuster spring.
  • Install the outboard return spring.
  • Adjust the parking brake shoes and install the rotor, caliper and wheel.
  • Lower the vehicle and tighten the wheel lug nuts to 100 ft. lbs. (135 Nm).
ADJUSTMENT
  • Measure the inside of the drum portion of the rear brake rotor
  • Remove the rear disc brake rotor.
  • Using Brake Adjustment Gauge D81L-1103-A or equivalent, measure the inside diameter of the drum portion of the rear disc brake rotor.
  • Subtract 0.020 in. (0.508mm) from the first measurement, adjust the brake shoes to that size
  • Adjust the parking brake adjuster screw until the outside diameter of the parking brake shoes measures 0.020 in. (0.508mm) less than the drum measurement.
  • Install the rear disc brake rotor.
Reassembly Reassembly is easy. Put new or machined rotors back on by sliding them over the lugs (they should slide on easily.) Loosen bleeder valve (having a catch bottle handy is good). Push calipers in slowly (using a c-clamp or large channel lock pliers), close bleeder valve. Put on pads. Lubricate metal clips with small amount of anti-seize. Re-adjust the emergency brake by turning the opposite direction from loosening. Refill the brake master cylinder

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

Trying to remove and replace rear brake rotors


First, make sure your parking brake is off.
Remove the rear caliper and then the brake pad housing. In the center hub of the rotor the parking brake shoes are located. The may need to be loosen first. There is a hole between 2 of the studs you need to align at the bottom. Look in the hole with a flashlight and find the star wheel. Use a screw driver to turn the wheel up a few turns to loosen the parking brake shoes from the rotor hub.
After that there are 2 threaded holes in the rotor near the studs you put two 8mm bolts in and slowly tighten each and it will pull the rotor off the hub. They rust up pretty bad so use penetrating oil on them.
