Chevrolet 19213356 Cylinder Asm,Rear Brake

To remove the brake drum and brake shoes, start by unscrewing the brake line fitting from the rear of the wheel cylinder using a flare-nut wrench to avoid rounding off the corners. Be careful not to pull the metal line out of the wheel cylinder. Next, remove the two bolts securing the wheel cylinder to the brake backing plate and then remove the wheel cylinder. To prevent the loss of brake fluid and the entry of dirt, plug the end of the brake line. For the overhaul process, disassemble the wheel cylinder by removing the rubber boot from each end, pushing out the pistons and cups, and removing the cup return spring and expander. Replace the rubber parts with new ones from the rebuild kit. Inspect the pistons for scoring and scuff marks and replace them if necessary. Check the cylinder bore for score marks and corrosion, and if present, consider honing or replacing the cylinder. Clean the cylinder with brake system cleaner or denatured alcohol and ensure the bleeder screw hole is clean. Lubricate the cylinder bore with clean brake fluid and insert the new rubber cups, making sure the lip faces in. Install the expander spring and remaining cup, attach the rubber boots to the pistons, and then install the pistons and boots. Finally, for installation, attach the brake line to the wheel cylinder before tightening the mounting bolts and line fitting. Use a flare-nut wrench if available. Bleed the brakes and thoroughly test their operation before driving the vehicle in traffic.
