99 Chevy Tahoe squeal

99 Chevy 2 door 4wd Tahoe 5.7L 131,000 miles.
Recently started squealing near front passenger wheel when in gear moving forward slowly. Drive Belt replaced at 110,000 miles. Front brake pads, rear brake shoes replaced 115,000 miles, rotors and drums are the same as when I bought it at 80,000 miles. The squeal begins when releasing the brake from a stop and continues when idling/moving slowly until the vehicle is moving about 20-30 mph. Particularly bad in parking lots, at least thats when I can hear it the most, because the car is moving slowly. For all I know it could be making the noise on the highway but I can't hear it. No Check Engine Light. Stopping/Braking distance is normal. Brake Fluid is full. No other mechanical problems. Please Advise.
