  Q: How to replace the wheel cylinder on Chevrolet Cobalt?

  A: In replacing the Wheel Cylinder, first, lift and support the vehicle, then remove the tire and the wheel assembly and then the Brake Drum. Debris and contaminants surrounding the Wheel Cylinder should be removed prior to removing the Wheel Cylinder bleeder cap and valve and brake pipe fitting from the said element, exposing brake pipe end and capping the said end to prevent brake pipe loss and contamination. Next, take off the Wheel Cylinder mounting bolts and using the j 38400 Brake Shoe spanner and spring remover (J 38400), open the top of brake shoes wide enough so as to take off the Wheel Cylinder from the Brake Backing Plate. For installation, use once more the j 38400 to spread the top of the brake shoes apart and place the new Wheel Cylinder into the Brake Backing Plate, and then install the Wheel Cylinder mounting bolts and tighten them to 16 nm (12 ft. Lbs.). On the opposite end of the brake pipe, remove the cap and join the brake pipe fitting at the Wheel Cylinder and screw it full to a torque rating of 19 nm (14 ft. Lb.). Mount the Wheel Cylinder bleeder valve by tightening it to a set of 8 nm (71 inch lbs.), mounting the Brake Drum, bleeding out the hydraulic brake system, and mounting the cap for the bleeder valve. Finally, adjust the drum brakes, mount the tire and wheel assembly, and drop the vehicles.
