This requires bleeding of the hydraulic system after it has been correctly connected. The hydraulic system can be bled manually or with pressure bleeding equipment. NOTE: When a new brake master cylinder has been installed or the system has been emptied or partially emptied, it must be primed to prevent air from entering the system. 1. For in-vehicle priming, disconnect the brake lines from the brake master cylinder (2140). Master Cylinder Priming In-Vehicle or Bench WARNING: Use of any other than painted and plastic surfaces. If brake fluid is immediately wash it with water. CAUTION: Do not allow the brake master operation. Keep the brake master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. Copyright 2002, Ford Motor Company Last updated: 6/1/2006

Fill the brake master cylinder reservoir with High Performance DOT 3 Brake Fluid 7. Loosen the brake outlet tubes at the master C6AZ-19542-AB or DOT 3 equivalent meeting Ford specification ESA-M6C25-A (United States and Canada only). If DOT 3 is not available, use Ford High Performance DOT 4 Brake Fluid meeting Ford specification SAE J1704. cylinder one at a time. 8. Tighten the outlet tubes. 3. Slowly depress the primary piston or, for in-vehicle priming, have an assistant slowly pump the brake pedal until clear brake fluid flows from both brake tubes with no air bubbles. 4. If necessary, install the brake master cylinder into the vehicle. For additional information, refer to Section 206-06. 5. Remove the short brake tubes and install the master cylinder outlet tubes. 9. Repeat the above three steps until no air bubbles are seen in the expelled brake fluid. 10. Bleed the brake system. For additional information, refer to Brake System Bleeding in this section.
206-00-3 Brake System General Information 206-00-3 Four Wheel Anti-Lock Brake System (4WABS) Hydraulic Control Unit (HCU) WARNING: Use of any other than Vehicles with rear drum brakes 2. Connect a clear drain tube to the RH rear bleeder screw and the other end in a container partially filled with recommended brake fluid. painted or plastic surfaces. If brake fluid is immediately wash it with water. CAUTION: Do not allow the master operation. Keep the master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. Vehicles with rear disc brakes 3. Connect a clear drain tube to the RH rear bleeder screw and the other end in a container partially filled with recommended brake fluid. NOTE: This procedure only needs to be carried out if a new 4-wheel anti-lock brake (4WABS) hydraulic control unit (HCU) has been installed. 1. Clean all dirt from and remove the brake master cylinder filler cap (2162), and fill the brake master cylinder reservoir with the specified brake fluid. 4. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal. 5. Loosen the RH rear bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the bleeder screw. Repeat until clear, bubble-free fluid comes out. Refill the brake master cylinder reservoir as necessary.

WARNING: Use of any other than Vehicles with rear disc brakes painted or plastic surfaces. If brake fluid is 7. Tighten the bleeder screw. immediately wash it with water. CAUTION: Do not allow the master operation. Keep the master cylinder reservoir filled with the specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. 8. Repeat Steps 2-7 for the LH rear bleeder screw, the RH front bleeder screw and the LH front bleeder screw, in that order. 1. NOTE: It is not necessary to do a complete brake system bleed if only the disc brake caliper was disconnected. Place a box end wrench on the disc brake caliper bleeder screw. Attach a rubber drain tube to the disc brake caliper bleeder screw, and submerge the free end of the tube in a container partially filled with clean brake fluid. 9. NOTE: Go to the help menu on the scan tool. The Ford Service Function Card (FSF) must be used to get the help menu. Connect the NGS DLC cable adapter into the vehicle data link connector (DLC) under the dash, and follow the scan tool instructions for bleeding. 10. Repeat the conventional bleed procedure as outlined in Steps 2-7. 2. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
206-00-5 Brake System General Information 206-00-5 3. Loosen the disc brake caliper bleeder screw until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten the disc brake caliper bleeder screw. Repeat until clear, bubble-free fluid comes out. Refill the brake master cylinder reservoir as necessary. 4. Tighten the disc brake caliper bleeder screw. For additional information, refer to Specifications in this section.
