Lift and secure the rear of the vehicle, block the front wheels. Remove rear wheels, hub/drum, and brake shoes. Disconnect and plug the brake line. Remove the wheel cylinder. Clean the backing plate and wheel cylinder surfaces. Apply sealant to the backing plate. Install the wheel cylinder, tighten bolts. Unplug the brake line, insert it into the wheel cylinder, tighten the nut. Reinstall brake shoes, hub/drum. Bleed the brakes. Reinstall wheels, lower the vehicle. Test brakes before normal use.

First of all, to overhaul a wheel cylinder, make sure to prepare a clean workspace. Remove the wheel cylinder and check the bleeder screw. You can remove the boots from the cylinder and use cup expanders to remove the piston, cups, and spring. Clean these parts with brake fluid or denatured alcohol and dry with compressed air. Check the cylinder bore and piston for damage, replacing if needed. Lubricate the components before installation. Install the expansion spring and cup expanders, then the cups. Attach the boot to the piston and insert into the bore. Repeat for the remaining boot and piston. Install the bleeder screw.

If an overhaul is indicated, usually due to fluid leakage or sticky operation, explore all options before beginning the job. New wheel cylinders are available, making this task quite easy. If you choose to rebuild the wheel cylinder, ensure a rebuild kit is available beforehand. Never overhaul just one wheel cylinder; always rebuild both simultaneously. To remove the wheel cylinder, first take off the brake shoes, then unscrew the brake line fitting from the rear of the wheel cylinder. Use a flare-nut wrench if available to avoid rounding off the corners on the fitting, and do not pull the metal line out of the wheel cylinder to prevent bending. Next, remove the two bolts securing the wheel cylinder to the brake backing plate and take out the wheel cylinder. Plug the end of the brake line to prevent fluid loss and dirt entry. For disassembly, remove the rubber dust boot from each end of the cylinder, then push out the two pistons, cups, and cup expanders along with the spring assembly. Discard the rubber parts and use new ones from the rebuild kit during reassembly. Inspect the pistons for scoring and scuff marks; if any are found, replace the wheel cylinder. Check the inside of the cylinder bore for score marks and corrosion; honing may restore it slightly, but replacement is recommended. If the cylinder is in good condition, clean it with brake system cleaner, remove the bleeder screw, and ensure the hole is clean. Lubricate the cylinder bore with clean brake fluid, then insert one of the new rubber cups with the lip facing in. Install the cup expander and spring assembly from the other side, followed by the remaining cup in the cylinder bore, then install the pistons and boots. For installation, reverse the removal steps, attaching the brake line to the wheel cylinder before installing the mounting bolts, and tighten the line fitting after securing the wheel cylinder mounting bolts. Use a flare-nut wrench if available to ensure a secure fit. Finally, install the brake shoes and brake drum, and bleed the brake system. Do not drive the vehicle in traffic until brake operation has been thoroughly tested.

Place the cups in each end of the cylinder, ensuring the open ends face each other.

Install the wheels and lower the vehicle.
