Front brake rotors

First you want to remove brake fluid from brake resovoir, raise front wheels off ground and set park brake or block rear wheels. Remove front wheels, keep steering wheel unlocked so you can turn rotors side to side. Loosen bolts that hold caliper end gently pry caliper free from rotor, remove caliper and remove pads, use bungy cord to hang caliper away from rotor, have rotors measured to see if they are thick enough to have machined, replace if out of specs. Match up pads with old ones, use anti- squeak red liquid and put layer on back of pads, let dry. Use tool to put pistons back into calipers, slowly put pistons back into bore while opening up bleeder screw so ABS won't be damaged. After rotors resurfaced, wash with rubbing alchohal to remove any oils from hands, install rotors and reverse putting pads back onto caliper and reinstall, torque caliper bolts to factory specs and tighten bleeder screws. Install wheels, torque lug nuts to factory specs and replace brake fluid in resovoir. Lower car carefully to ground and press brake peddle without pumping it. Any air in system should bleed out, if not get someone to help with bleeding system. Road test to ensure no squeaks or pulling, burn brakes in slowly.

Remove the wheels
Stick a punch or something sturdy in a rotor cooling hole so it jams against the caliper. Loosen the 8 nuts that can be accessed through the 8 holes in the hub flange.
Remove the calipers from the knuckles and hang them from something other than the brake hose.
Remove the previously loosened 8 rotor nuts.
Tap the rotor with a hammer and it should fall off.

1. Loosen but do not remove lug nuts on wheel
2. Jack vehicle up (make sure you are on level ground and the vehicle is stable)
3. Locate and remove the bolts that hold the caliper.(the caliper has a rubber brakeline attached to it)
4. Remove caliper leaving rubber brake hose attached (may be necessary to pry and do not let the caliper hang by that hose)

Now it gets tricky because I dont know what kind of car it is. Some cars you can just slide the rotor off from this point. Others you have to remove a screw or bolt in the rotor to remove, some you have to take the bust cap off and remove nut. It really varies by type of vehicle.

1. Put your car on a level spot for safety and start your car Sienna.
2. For left front rotor, turn your steering wheel to the left all the way and stop the engine. DO NOT put emergency brake on! Put stopping blocks on the passenger front front, rear right and rwear left for safety.
3. Half loosen all front left tire nuts and jack up the left front then loosen all nuts and take the wheel off.
4. Use a 3" G-clamp from Lowes, Home Depot or any store near you, press against brake cylinder so that brake fluid flows back to its reservoir
4. Remove one bolt on the caliper and the other bolt loosen and lift the caliper with the other bolt on and rest on a block. Do not take the rubber hose off nor attend to loosen any brake fluid pipes and nuts.
5. Remove brake pads and remove the nuts on the rotor, done.
If you need further assitance please let me know and if this assisted you please feel free to rate the solution accordingly. Thanks, Midwest-tek

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

not that hard depending on type of vehicle u drive -front wheel=4x4=all wheel etc--need to remove brake caliper and caliper bracket and rotor unplug abs if front wheel drive can loosen center hub nut -than remove bolts at rear of brake plate tap hub nut to loosen off axle remove nut remove hub this is a basic example on removal u didnt state what vehicle u were removing hub

Slightly loosen tire lug nuts, raise car with jack, remove lug nuts and wheel, remove caliper bolts from brake calipers. Open cap on brake fluid reservoir, place folded towel over top of reservoir and set cap on the paper towel to hold it in place, use a large 9-inch C-clamp to squeez in on front brake pad about 1/8 inch. REmove caliper from rotor. Hang caliper from shock coils with strong bungie strap so there is no pressure on the brake line. Remove bolts from caliper plate and remove caliper plate. Using oversized phillips screwdriver end attached to a 3/8 inch flex wrench, you will carefully put light pressure in a counter-clockwise direction to remove the brass screws and tap the flex wrench at the same time with a large 3-pound hammer driving the screwdriver end into the top of the screw as you put more pressure on the wrench to loosen the screw. This is about the only way to remove brass screws without "damaging them" and they are a dealer item not found in parts store. There should be two screws holding the rotor on. Then spray liquid wrench or penetrating oil into all holes on rotor toward center to help dissolve rust. Wait three minutes then tap rear of rotor lightly with large hammer taking care NOT to hit the thin metal rotor shield. Eventually, this tapping force will loosen the rotor. Use same technique of tapping the flex wrench when applying pressure to wrench to tighten the brass screws when replacing the rotors.

It sounds like your hub/rotor is froze on....you'll need to apply some penetrant in the lug stud areas as wells as the area where the rotor mates to the axle hub.
