Ford Mustang (1999-2004) Service Manual: Master Cylinder Priming - 4.6L
1. CAUTION: Use only bleed screws on the engine side of the brake master cylinder (2140). The hydro-boost bleed screw, located near the dash on the hydro-booster casting, is for the booster cavity filled with power steering fluid, not brake fluid.
Connect a clear waste line to the bleed screw closet to the booster first and the other end in a container partially filled with recommended brake fluid.

2. Open the bleeder screw, have an assistant push the brake pedal down slowly through full travel, close the bleeder screw, then return brake pedal slowly to full released position. Wait five seconds, then repeat operation until air bubbles cease to appear.
3. Repeat Step 2 for bleeder screw farthest from hydro-booster.
