Toyota Harrier Club?

last week when i sent my car to change tires, and i also told the mechanic to clean away the dust in the drums...but recently, my handbrake was so tight where 1 or 2 clicks will prevent the car from rolling if i engage D mode..previously when i engage D mode, the car will move abit... so, when i try to remove the brake drum cover, it was so tight and eventually removal was successful, but fitting it back was super hard, the cover blocked by the brake shoe...hmm..not to mention, left drum...
