What does a brake wheel cylinder do?

The wheel cylinder is part of your vehicle's drum brake system. When you press the brake pedal, hydraulic fluid pressure is sent to the wheel cylinder, which forces pistons outward. These pistons push the brake shoes against the inside of the brake drum, creating friction to slow or stop the vehicle.

Do I need to replace both rear wheel cylinders?

It's generally recommended to replace brake components in pairs. If one wheel cylinder is worn out, the other on the same axle is likely close to failing. Replacing both ensures balanced braking performance on the rear axle.

Does this wheel cylinder come with hardware?

This DFC brake wheel cylinder is sold individually and does not include installation hardware such as seals or boots. You may need to reuse your existing hardware or purchase a separate brake hardware kit.
