If replacement is necessary due to fluid leakage or sticky operation, it is important to consider all options before starting the job. New wheel cylinders are available, making the task relatively easy. It is crucial to always replace both wheel cylinders at the same time, rather than just one. To remove the wheel cylinder, begin by removing the rear brake shoes. Then, using a flare-nut wrench, disconnect the brake line fitting from the rear of the wheel cylinder and plug the end of the brake line to prevent fluid loss and contamination. Remove the two bolts securing the wheel cylinder to the backing plate and remove the wheel cylinder. To install the new wheel cylinder, follow the reverse steps of removal. Tighten the wheel cylinder mounting bolts to the specified torque and ensure the line fitting is securely tightened. Install the brake shoes, wheel hub/bearing assembly (if removed), and brake drum. Finally, bleed the brakes and carefully test brake operation before resuming normal operation.
