Rear calibers or wheel cylinders are sticking. This is most often due to brake fluid that is contaminated with moisture. This moisture will cause internal parts to rust. Replace the rear calibers/wheel cylinders and replace the brake fluid with fresh fluid from an unopened can. It can also be a defective proportioning valve.
On most cars the handbrake is applied to the rear wheels only. The footbrake applies to both the front and back brakes, with a bais to the front to help avoid the rear wheels locking up under heavy braking.
Braking
The rear brakes will lock when there isn't enough weight in the rear of the vehicle, the surface is loose (like a gravel road), or they [the brakes] are applied to heavily. Newer vehicles with anti-lock brake systems (ABS) should not have this problem.
If the rear wheel brakes are locking up on a vehicle they should be thoroughly checked. The master cylinder may need to be replaced on the car.
that nosie is the wheels locking up, this doesnt usually happen in modern cars as they have anti-lock brakes.
At the back behind the wheels??????

Parking brakes apply generally on rear wheels to control enough sliding of the vehicle.
brakes on all 4 wheels
A 1991 mercury topaz has drum brakes on the rear wheels.
The problem with the rear brakes locking up may be the self adjusting screws themselves. They should only tighten when reversing the car and hitting the brakes, putting the pressure on the drums in back instead of the rotors in front.
When brakes are applied too hard and wheels lose traction, two main types of skids can occur: front-wheel skid and rear-wheel skid. A front-wheel skid happens when the front wheels lose grip, causing the vehicle to slide straight ahead, often leading to understeering. In contrast, a rear-wheel skid occurs when the rear wheels lose traction, resulting in oversteering, where the rear of the vehicle swings out. Both types can compromise vehicle control and increase the risk of accidents.
