Manual Bleeding Method
WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.
WARNING: Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft products call: 1-800-959-3673. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury.
CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with clean, specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system. Damage to the brake system components may occur.
CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.
NOTE: When any part of the hydraulic system has been disconnected for repair or replacement, air can enter the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after the repair is finished or after the new component is installed. The hydraulic system can be bled manually or with pressure bleeding equipment.
1. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with clean, specified brake fluid.
2. Remove the bleeder screw cap and place a box end wrench on the RH rear bleeder screw. Attach a rubber drain hose to the RH rear bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.
3. Have an assistant pump the brake pedal at least 3 times and then hold firm pressure on the brake pedal.
4. 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 RH rear bleeder screw.
^ Repeat until clear, bubble-free fluid comes out.
^ Refill the brake master cylinder reservoir as necessary.
5. Tighten the RH rear bleeder screw and install the bleeder screw cap.
^ Tighten to 16 Nm (12 lb-ft).
6. Repeat Steps 2 through 5 for the LH rear, RH front and LH front bleeder screws in this order.
^ Refill the brake master cylinder reservoir as necessary.
Pressure Bleeding Method
WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.

1. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with clean, specified brake fluid.
2. NOTE: Master cylinder pressure bleeder adapter tools are available from various manufacturers of pressure bleeding equipment. Follow the instructions of the equipment manufacturer when installing the adapter.
Install the bleeder adapter to the brake master cylinder reservoir and attach the bleeder tank hose to the fitting on the adapter.
3. NOTE: Bleed the longest line first. Make sure the bleeder tank contains enough clean, specified brake fluid to complete the bleeding operation.
Remove the bleeder screw cap and place a box end wrench on the RH rear bleeder screw. Attach a rubber drain hose to the RH rear bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.
4. Open the valve on the bleeder tank.
5. Loosen the RH rear bleeder screw. Leave open until clear, bubble-free brake fluid flows, then tighten the RH rear bleeder screw and remove the rubber hose and install the bleeder screw cap.
^ Tighten to 16 Nm (12 lb-ft).
6. Continue bleeding the system, going in order from the LH rear bleeder screw to the RH front disc brake caliper bleeder screw ending with the LH front disc brake caliper bleeder screw.
7. Close the bleeder tank valve. Remove the tank hose from the adapter and remove the adapter from the brake fluid reservoir.
Anti-Lock Brake System (ABS) Bleeding
WARNING: Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.

NOTE: When any part of the hydraulic system has been disconnected for repair or replacement, air can enter the system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after the repair is finished or after the new component is installed. The hydraulic system can be bled manually or with pressure bleeding equipment.
NOTE: Bleeding the hydraulic control unit (HCU) is required only when removing or installing the HCU, master cylinder, or opening the tubes and hoses to the HCU.
1. NOTE: Carrying out the System Bleed function drives trapped air from the HCU. Subsequent bleeding removes the air from the brake hydraulic system through the bleeder screws.
NOTE: Adequate battery voltage is required during the anti-lock control portion of the system bleed.
Connect the scan tool.
2. Access the SYSTEM BLEED FUNCTION and follow the directions on the scan tool.
3. Manually bleed the brake hydraulic system.
4. Repeat the procedure carrying out a total of 2 scan tool cycles and 2 manual bleed cycles.
