DFC 79-81 Honda Civic Rear-L Brake Wheel Cylinder

This is the rear-left brake wheel cylinder for your 1979-1981 Honda Prelude or 1980-1981 Honda Civic. This part is a key component in your drum brake system, working with the brake shoes to create friction against the drum when you press the brake pedal. It's essentially a small hydraulic cylinder that pushes the brake shoes outward.

When you apply the brakes, hydraulic fluid pressure from the master cylinder is sent to this wheel cylinder. The pressure forces the pistons inside the cylinder to move outward, pushing the brake shoes against the rotating brake drum. This friction slows and stops your vehicle. Over time, seals can wear out, leading to leaks or reduced braking performance, making replacement important for safety and proper function.
