In a drum brake system, the Wheel Cylinder puts pressure on the brake shoes, which when pressed against the drum, slows down and stops the vehicle. The cylinder is connected to the shoes by small rods. In older cars, the cylinders may leak and hinder braking power, but cylinders are relatively inexpensive to replace.

How does a brake cylinder work?
The brake master cylinder is a component in your car's braking system that drives the pressure generated by the brake pedal to the braking mechanism at your vehicles' wheels. ... When you press down on the brake pedal, that force pushes a piston through the brake cylinder, converting the force into hydraulic pressure.
What's the difference between master cylinder and wheel cylinder?
Pressing on the brake pedal generates a hydraulic pressure in the master brake cylinder which is transmitted to the wheel cylinder in the brake fluid via the brake lines. In the wheel cylinder, the hydraulic pressure acts on the pistons, which then exert mechanical pressure on the brake shoes.
Can a wheel cylinder be bad without leaking?
