How to fix the rear wheel lock-up on Lechi?

[McStephen]

First, drive forward and then backward three times, making sure not to move too much, otherwise the brake pads and brake drum won't separate. Pour 100°C boiling water between the brake pads and brake drum; the thermal expansion might cause them to separate automatically. Tap both sides lightly, which might help separate them; if that doesn't work, try kicking the tire a few times—it might loosen up.
