2005 Chevrolet Cavalier Wheel Cylinder

You can install the Brake Booster, ensure that the inner washer is in position on the brake pedal, apply a thin coating of lithium grease to the pushrod pin, connect the brake booster pushrod, install the outer washer and retaining clip, install the vacuum brake booster mounting nuts, install the vacuum hose, move the master cylinder and the proportioning valve assembly or the antilock brake modulator assembly onto the brake booster studs, install the master cylinder mounting bolts and install the air cleaner assembly.

The procedure is to remove the Brake Master Cylinder, secure the mounting flange of the brake master cylinder in a bench vise, clean the outside of the master cylinder reservoir, remove the reservoir cap and diaphragm from the reservoir, inspect the reservoir cap, remove the master cylinder reservoir, depress the primary piston and remove the piston retainer, remove the primary piston assembly, plug the cylinder inlet ports and the rear outlet port and discard the primary piston assembly, the piston retainer, and the seals and seal retainer from the secondary piston.

You can use only Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container.
