Chi chi sound from rear brake ONLY when pedal pressed lightly

[asjdsm]

Dear brothers I need your help again. Mashallah the brake is not making any noise now. But when I stand the bike on double stand and rotate the wheel, i can feel that at some points there is a noise like the drum is touching the brake shoe. I rotate the wheel and it comes to a stop suddenly. At that point when I try to move it I can feel some resistance and hear a noise like something is rubbing against the drum of the tyre. Kindly advice brothers
