Parking brakes are very sensitive on these cars.
They are a drum brake operating on the drum inside the rear brake disc
If not used, the brake drum lining rusts and then the pads do not grip.
Additionally, if you have washed the car and the drums got wet inside, and you put the park brake on, they can rust to the drum and stick, resulting in a BANG when they release when the wheel starts rolling. Happened to me last week, locked the wheel in reverse, I had to go D-N-R a few times and a bit of engine power to release the park brake.
It then proceeded to squeal - but this may also be my disc brakes as that wheel was warmer than the others that day.
If the drum has rusted too much, then you need new drums and new park brake shoes.
The park brake should hold the car of an 18% incline - that's quite a steep hill - both pointing downhill and uphill. If it doesn't, and/or you need to depress the foot level more than 6 clicks, then it needs inspecting / cleaning / adjusting and maybe renewing the discs/pads.
And if you do have wheel brake squeal, inspect all wheels for rubbing brakes (easy with a IR thermometer after a few miles driving - the wheel with rubbing brakes will be a lot warmer than the others). The garage can disassemble, clean, lubricate and reassemble. This normally fixes it.
