If you suspect that your power steering system is in need of a major overhaul, typically because of the leakage or a slobby functionality, it is high time to consider all the possibilities before starting the work. New wheel cylinders are available today, and so therefore seeing what I have explained above, it is quite easy to do it. If the task of rebuilding the wheel cylinder is selected, it is necessary to have a rebuild kit beforehand. It is important not to rebuild one wheel cylinder at a time and always the two of them. First, apply the handbrake, turn off the engine and chock the front wheels, then jack up the rear of the vehicle and support it on jackstands. Take out the brake shoe assembly, and scrub all the area that surround the wheel cylinder to eliminate those dirt and other related substance. If you can get a flare-nut wrench, remove the brake line but otherwise undo the two wheel cylinder bolts and do not pull on the brake line. Subsequently, exhaust the wheel cylinder by unscrewing the wheel cylinder mounting bolts and pulling the wheel cylinder from the brake backing plate, then, lay the wheel cylinder on a work sta- tion and quickly plug the brake line to minimize fluid spillage and contamination. To start with, when retrofitting the following components should be dismantled from the wheel cylinder body; bleeder screw, cups, pistons, boots, and spring assembly. Scrub the wheel cylinder with brake fluid, denatured alcohol, or any cleaner that is appropriate for brake system but not petroleum. After that, the wheel cylinder should be dried with compressed air and the passages should be blown out. Inspect the bore for rust and scratches; light rust can be rubbed with crocus paper, and if, notwithstanding, other defects cannot be scraped out or if the bore is scratched, a new cylinder is needed. Clean the new cups with brake fluid and fit all other brake cylinder assembled parts, with the cup lips facing the interior of the brake cylinder. To fix, secure the wheel cylinder in place, screw the bolts and only tight them up to the point where you can just unscrew them using your fingers; thread the brake line keenly in a fashion that does not harm the threads. thread in the wheel cylinder bolts up to the estimated torque and ensure that the brake line is fixed properly before refitting the brake shoe. Last but not the least Remind the driver to Bleed the brakes and ensure that the brakes operate are checked properly before using the automobile.
