REMOVE OR DISCONNECT
1. Retainer and electrical connector from fluid level sensor.
2. Drain brake fluid from master cylinder reservoir.
3. Reservoir hose from master cylinder. Plug hose to prevent fluid loss and contamination.
4. Brake pipes from master cylinder. Plug open pipes to prevent fluid loss and contamination.
5. Two attaching nuts.

INSTALL OR CONNECT
1. Reservoir onto master cylinder, as needed. Bench bleed master cylinder prior to installation to remove any trapped air. Perform this procedure on a level surface. Using a tool that will not score the bore of master cylinder, apply pressure to the plunger as many times as needed to circulate the brake fluid completely through the master cylinder. Allow the brake fluid and trapped air to be released through the inlet and outlet ports on the master cylinder.
2. Master cylinder onto power booster.
3. Attaching nuts. Tighten to 27 Nm (20 ft. lbs.).
4. Brake pipes. Tighten brake pipe fittings to 15 Nm (11 ft. lbs.).

6. Fill master cylinder reservoir to full level mark using only Delco Supreme II Brake Fluid, or equivalent DOT-3 brake fluid, as specified.
7. Electrical connector to fluid level sensor, secure with retainer.
