Saturn 22706688 Wheel Cylinder

If replacement is advised-typically because the wheel cylinder is leaking or sticking-it's suggested to replace the cylinders in sets rather than overhaul them. First of all, lock the wheels with the intention of not allowing the car to roll forward; then, remove the nuts of the rear wheel lug-, lift the rear of the car and put it on the jack stands. Take off the wheel and the brake shoes taking a lot of care to see that all dirty and foreign substance are cleared from round the wheel cylinder. Now at the back of the backing plate remove the brake line nut using flare-nut wrench if available but when doing this do not pull the brake line away from the wheel cylinder so that you do not kink it. Following this, take out the wheel cylinder mounting bolts and then take off the wheel cylinder from the backing plate. For installation, properly align the new wheel cylinder then engage the brake line fitting up to the thread and tighten it only finger tight and then put and tighten the two mounting bolts of the wheel cylinder in correct torque in such a manner that the brake line fitting is tightly seated. Replace the brake shoes then the brake drum on the hub flange and finally put the wheel and the lug nuts. Bleed the brake system, lower the vehicle to the ground, and then over tighten the lug nuts to the standard recommended torque. Last of all, honestly carry out a check on the brakes to determine how effectively it can stop before engaging the automobiles on the road system.
