I have a 1994 Pontiac Bonneville and I am trying to remove the rear brake drums. The brakes are tight so I have removed the e-brake cable. They are still tight and there is NO access hole to get inside and loosen the star wheel. I thought every car has one of these holes. Any ideas how I'm going to loosen the brakes so I can get the drums off?

The center part can get a little rust and hold the drum tight. Try a little penetrant there and tap it around the outside opf drum with a hammer.
If there are two holes opposite each other just out from the center of drum, but not as far out as the wheel studs, these are threaded holes to screw in two "8 X 1.25" bolts about 1 inch long, and push the drum outward. Screw the bolts in evenly and you will see the drum start inching outward.
If they are disc brakes, the bleeder valve will be on the brake caliper. If they are drum brakes, look on the back side of the brake backing plate. The bleed valve will be on the brake wheel cylinder. The valves probably have a little protective rubber boot on them.
first remove the tire you want to work on, then try to pull the drum out if the drum fills like stuck must to retract the udjuster, you do this removing a small rubber plug will be on the back of the back plate, just on top of the brake line connected to the wheel brake cylinder, you rotate the adjuster to release the tension on the adjuster so you can able to pull the drum out, note the on some vehicles you have to remove the big nut on the center of the drum, in order to remove the drum out. hope this will help Thanks.
If you have drum brakes on the rear and I am pretty sure you do, and you had to remove the drums you will need to adjust the rear brakes back to the point of almost touching the drum while jacked up and spinning the tire. Not to tight. The brakes are probably traveling so far to hit the drum that they lock up. This will be more noticeable when raining or damp weather. Hope this helps.
The rear wheel bearing on a toyota camry is replaced by replacing the wheel bearing and hub as a unit. this is a design change as compare to older models with two piece wheel bearings. Scotch drive wheels. Remove rear wheel. Remove rear brake drum. (note: if emergency brakes are applied you will not be able to remove brake drum) Remove dust cap and hub retaining nut. Hub should slide off as unit. Replace hub with new unit. Installation is reverse of removal.
I believe the 94 Sunbird's have rear emergency brakes. The rear brakes are drum brakes and it's very hard for them to lock up but should slow the car down to a stop and hold it from moving when at a stop.
The way they work is, the emergency brake cable pulls on the one of the brake shoes to the brake drums on each side so you only have 50% of your braking power to start with.
If your brake's are not holding when it's at a stop position, the brake shoes are warn or glazed over and need to be replaced.
You can try adjusting then by backing up a few times like say 7 times and giving it full brake application. That should adjust the brakes if the self adjusters are still working.
Good luck and hope this helps
i think your aware of how to change the brakes if im right and your problem is the rusted drum doesnt want to come off the only way to get the old drum off is to remove adjuster plug from behind drum dustshield and adjust the shoes so that there not even close to the braking area of the drum then try and wiggle the drum off of the assembly if it is not coming off then you need to use the old nylon hammer on the drum and i mean you must hit the drum from side to side trying by hand to wiggle the drum off its a tight fit and you need to strike the drum on the face not on the fins not wanting to damage with persistance and care and patience you will eventually be able to remove the drum to service brakes take care and good luck with it
