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.
