Installation (Neon Without ABS)

If removed, install the proportioning valves in their master cylinder ports. The valves are identical, so they can be installed in either master cylinder port going to the rear brakes. Ensure the "O" rings on the proportioning valves are new.
Bleed the master cylinder before installing it in the vehicle. See MASTER CYLINDER under BLEEDING BRAKE SYSTEM.
Inspect and wipe clean "O" ring vacuum seal on the master cylinder rear mounting flange to ensure a good vacuum seal once installation is complete. Replace as necessary.
Wipe the face of the power brake booster clean where the master cylinder seal comes in contact when it's installed. Do not get any cleaner or debris inside the booster.
Position the master cylinder on the studs of the power brake booster, aligning the push rod of the power brake booster with master cylinder piston push rod. Carefully push the master cylinder onto the studs until it contacts the face of the booster.
Install the 2 master cylinder mounting nuts. See TORQUE SPECIFICATIONS .
Connect the 4 brake tubes to the master cylinder and proportioning valve ports. See Figure . See TORQUE SPECIFICATIONS .
Connect the brake fluid level switch wiring connector.
Install the battery and clamp it in place.
Connect the positive and then negative battery cable.
Fill the master cylinder to the proper level.
Pump the brake pedal several times, then check brake fluid level in master cylinder reservoir. Adjust brake fluid level if necessary. See CHECKING & FILLING under BRAKE FLUID in SERVICE.

CAUTION: It will be necessary to bleed the entire base hydraulic system if the brake system has been open to air for excessive amount of time or air is present in the lines. See BLEEDING PROCEDURES under BLEEDING BRAKE SYSTEM.

Check for leaks.
Road test the vehicle to ensure proper operation of the brakes.
