How do i remove rear brake drum - 2004 Chevrolet Aveo

It's really pretty simple. Jack the truck up and rest it on jackstands on the frame of the truck. Remove the wheels, brake calipers "if it's disc brakes drums if it's drum brakes" remove the brake cable from the park brake assembly, remove the brake fluid lines from the wheel cylinders if it's drum brakes, remove the bolts holding the driveshaft to the rear yoke, remove the bolts holding the rear end to the leaf springs while the rear end is supported with the jack and then slowly let the jack down.... It's out!

You should jack up securely the rear end, and then remove the lugnuts to the wheels and remove the wheel.

Then, you may need a heavy hammer to tap on the 9 o'clock and 3 o'clock positions of the rear brake drum to loosen it up.

Yes, Undo the 32mm nut, first. And, don't get the bearings dirty with dust from the brake drums, or , if you do, replace the inner and outer bearings with new greased up ones. REAR DRUM BRAKES Brake Drums REMOVAL & INSTALLATION CAUTION
Brake linings contain asbestos. Asbestos is a known cancer-causing agent. When working on brakes, remember that the dust which accumulates on the brake parts and/or in the drum contains asbestos. Always wear a protective face covering, such as a painter's mask, when working on the brakes. NEVER blow the dust from the brakes or drum.

1. Raise the vehicle and support safely.
2. Remove the wheel and tire assembly.
3. On vehicles without rear bearing hub, remove the dust cap, cotter pin, nut lock, wheel bearing nut and washer from the spindle. Remove the outer wheel bearing. Remove the drum with the inner wheel bearing from the spindle. If the drum is difficult to remove, remove the plug from the rear of the backing plate and push the self adjuster lever away from the star wheel. Rotate the star wheel to retract the shoes. Remove the grease seal.

Can you tell me which type of axle you have?

Full Floating Axles To remove the drums from full floating rear axles, use the Axle Shaft Removal & Installation procedure in Section 7. Full floating rear axles can readily be identified by the bearing housing protruding through the center of the wheel.


Semi-Floating Axles

1. Raise and support the rear end on jack stands.
   
2. Remove the wheel.
   
3. Pull the drum from the brake assembly. If the brake drums have been scored from worn linings, the brake adjuster must be backed off so that the brake shoes will retract from the drum. The adjuster can be backed off by inserting a brake adjusting tool through the access hole provided. In some cases the access hole is provided in the brake drum. A metal cover plate is over the hole. This may be removed by using a hammer and chisel.
   

You may have to back off the automatic adjuster before you can pull the drum from the brake assembly

To install, reverse the removal procedure.

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
