The small screw (6mm) that you removed allows access to the 8mm-1.25 threaded portion of the hole that is in the rotor itself. After you have squited penetrating oil around the wheel studs get an 8mm x 40 - 1.25 hardened bolt (Torx head or Allen) and use it as a jack screw in 8mm hole you just cleared. Tighten the jack screw and rap the rear of the rotor with a lrge rubber hammer (rotating the wheel as you rap) then tighten the 8mm some more. Keep tightening , rapping and rotating. The rotor will come off. To prevent difficulty getting it off in the future, smear some anti-sieze on the inner contact surfaces and around the inside of the hub area. DO NOT GET THE ANTI-SIEZE ON THE WHEEL STUDS.
This should reduce the difficulty now and in the future.

They often rust in place, try hittig them with a hammer around the bolt holes to free them.  if they are loose but still don't come off the emergency brake will need adjustment inside the vehicle.

The rear breaks have pads and rotor, but also look like they have a drum set up. How do I remove the combination rotor and drum?


remove the caliper and the pads.remove the caliper bracket that is around the rotor that the caliper sits on.then some of these have 2 screws that hold the rotor to the hub,remove the screws and hit the centre of the rotor near the hub.if it doesn`t use screws then hit the rotor near the hub to pop it loose.you may have to heat up the rotor with a torch and hit it again to get it loose.if it uses an e-brakes system inside the rotor(the part that looks like a drum) then you may have to back off the e-brakes like you would with just drum brakes,or you could try to pry off the rotor knowing you may have to replace things inside the rotor for the e-brake system.

How to take back rotors off a 1994 honda civic.


PATH: Brakes > Front Disc Brakes > Brake Disc (Rotor) > Removal & Installation Removal & Installation
  1. Raise and support the front of the vehicle on jackstands. Remove the front wheels.
  2. Remove the caliper assembly; do not let the caliper assembly hang by the brake hose, instead support it with a piece of wire looped around the front spring or control arm.
  3. Remove the retaining screw from the brake rotor and remove the rotor from the hub.

An impact driver, No. 3 phillips screwdriver bit, and a hammer may be needed to remove the retaining screw. It is fairly easy to destroy the screw slots using an ordinary phillips screwdriver to remove the tightly driven screw (see photo).

  1. To install the disc, replace the disc on the hub, screw in the retaining screw and replace the caliper assembly.

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.

Can't remove rear disc brakes and roters to be replaced


If wheel and calipers are off, and no retainers on studs, spray some penetrating lube in center of hub where rotor slides over hub shoulder. Let it sit for a minute or two, then place a block of wood against outside edge of rotor and hit block with a hammer. May have to give it a good hit, around perimeter in a few spots to get it to jar loose in center at hub. Usually just rusted. Better if you have a big rubber mallet, and hit hard all around outside area of rotor, but block of wood will do the job as well.

Replacing rear brake pads


Don't do this if your not comfortable working on cars ... someone could get hurt ...or your car could. Make sure front wheel are blocked and car is in either park or first gear.
  1. Don't set the parking break.
  2. Lift corner up to remove tire.
  3. Remove the two shoulder bolts on back of caliper .. .10mm I think.
  4. Pull caliper up and forward. Don't let it hank by the brake line.
  5. Remove pad, making sure to not lose the small clip that holds onto the ears of the pads.
  6. You need to get a special tool to screw in the piston that is on the caliper. This can be obtained for about $15 at most automotive store.
  7. Be careful to not tear the rubber piston boot when screwing piston back in ... go slow.
  8. Wipe caliper off of any dirt. Don't use compressed air. Use a small wire brush to remove any corrosion in the area where the pad ears go, if needed.
  9. Replace new pads into caliper and remount caliper onto rotor.
  10. Screw shoulder bolts back in. Don't force them as the shoulder fits into a hole in the backing plate. You should almost be able to screw them in by hand. tighten good
  11. Get in car and work parking brake about 5 times. This adjusts the pads to the rotors.
  12. Repeat on other side.

Remove rear rotors


Assuming you have not done this veh or rear dics before. You should be able to get the calipers loose and wrestle them off. The Rotor question is what? Now the fun part. Screwing in the brake adjusters with or without opening a bleeder valve. Tell me what help you need.

Problem changing rear rotors on 95 Toyota Avalon


Just remove the rear rotors, bull the straight off, after removing the caliper bracket. It would be a good idea to spray the small brake shoes with brake cleaner. No need to remove anything other than the rotor.
