Question about 1991 Buick LeSabre
Stuck brake drums are a pain in the ----. They get stuck for 2 reasons. 1. The center hub rusts to the drum. Spray lots of penetrating oil around hub center where drum slides over it. Tap the face (Flat side facing out) of the drum with a hammer to help break it loose. U can also get under the car (make sure it's supported w/ safety stands, front wheels blocked) w/ a block of wood against the edge of the drum hit the wood w/ a hammer. Turn the drum so u hit it all around the edge. If this doesn't work go to next step, 2. The brake shoes wear the drum down, and there is a ridge left behind on the drum that prevents (or makes) removal very difficult. It's probably a combination of both 1 and 2. On the back of the wheel is 1 or 2 slots used for access to adjust the brakes. If you can get a view inside (maybe w/ the help of a mirror and flashlight) you will see threaded adjuster (going from front to back inside drum). There will be a small 'wheel' on one end. This wheel has teeth like a sprocket and is what u turn to adjust the brakes. There is a small metal lever that rests on this wheel between 2 sprockets that only allows it to be turned in one direction, which is to adjust the brakes to expand, which is NOT what u want to do. You want to turn it the opposite way, which means u need to get a very thin screwdriver, push the small lever away from the sprocket, while turning the adjustment sprocket in the direction to 'shrink' or 'unadjust' if I can put it that way. This will allow u to pull the drum over the ridge formed on the edge of the drum.lots of luck countrycurt0

Make sure that there are no screws holding it in place. Then soak the seam where the drum mates to the hub, using penetrating oil or PB Blaster and let it sit a little while to work. Then tap it around the edge with a hammer to break it free. Once it starts to separate, you can use a flatblade screwdriver to pry it off, working your way around the drum.
Just as a sidenote, make sure the parking brake is not set - that'll hold those drums on tightly enough that if you do manage to get them off (which is unlikely), you'll mangle the braking setup.
