Remove the lug nuts: Start by loosening the lug nuts that hold the brake drum in place. Use a lug wrench or a socket to turn the lug nuts counterclockwise until they are loosened.
Tap around the drum: Before attempting to pull the drum off, try tapping around the edges with a rubber mallet. This can help in breaking the bond between the drum and the shoes.
Use penetrating oil: Penetrating oil can be more effective than WD-40 in loosening the grip of the brake shoes on the drum. Spray the penetrating oil around the edges of the drum, where it meets the brake shoes, and let it soak for several minutes.
Use a pry bar: If the drum still does not come off, you may need to use a pry bar. Place the pry bar between the brake backing plate and the edge of the drum. Be careful not to damage the brake components. Gently pry the drum away from the backing plate while wiggling it back and forth until the drum loosens.
Check for obstacles: Ensure there are no obstacles or debris preventing the drum from coming off. Look closely for any objects that may be caught between the drum and the brake shoes or backing plate.
Avoid the brake line: Be cautious not to damage the brake line when prying the drum off. If the drum does not budge after a reasonable amount of effort, consider seeking assistance from a professional mechanic to prevent further damage to your vehicle's braking system.
