What does a brake wheel cylinder do?

The brake wheel cylinder is a hydraulic component located at each rear wheel. When you press the brake pedal, fluid pressure forces the pistons inside the cylinder outward, pushing the brake shoes against the inside of the brake drum to slow the vehicle.

Do I need to replace both rear wheel cylinders?

It's generally recommended to replace brake wheel cylinders in pairs on the same axle. This helps ensure even braking performance between the left and right rear wheels.

Does this wheel cylinder come with brake shoes or hardware?

This part is a brake wheel cylinder only. Brake shoes, springs, and other hardware are typically sold separately.
