How to replace and adjust rear brake shoes in a 150cc GY6 Chinese scooter

Torque specs:
Exhaust studs 10 N-m (7.3 ft-lb, or 88.5 in-lb)

Muffler to engine bolts 20 N-m (14.6 ft-lb or 177 in-lb)
Rear wheel nut 116 N-m (85 ft-lb)
The exhaust pipe and muffler is mounted in front of the rear wheel, so you would also need to remove it if you're working on the tire or brake shoes. Laying the scooter down on it's side makes it easier to work on the exhaust, but you don't have to do it that way.
