Use of any other than approved DOT 3 motor vehicle brake fluid will cause permanent damage to brake components and will render the brakes inoperative. Failure to follow these instructions may result in personal injury.
Carefully read all precaution 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 personal injury.
Never let the brake master cylinder reservoir 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.
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.
This procedure must be performed if a new Anti-lock Brake System (ABS) Hydraulic Control Unit (HCU) has been installed.
When any part of the hydraulic system is disconnected for repair or installation of a new component, air may enter the system and cause spongy a brake pedal. 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.
Carrying out the chassis brake bleeding procedure drives trapped air from the otherwise inaccessible lower section of the HCU valves into the upper sections (accessible by bleeding the brakes). Subsequent bleeding removes the air from the system.
Bleed the longest brake tube or hose first. Be sure the bleeder tank contains enough specified brake fluid to complete the bleeding operation.
Add clean, specified brake fluid as necessary throughout the procedure.
- If the vehicle is equipped with an ABS, connect the Vehicle Communication Module (VCM) and scan tool into the vehicle Data Link Connector (DLC) under the dash and carry out the chassis brake bleeding procedure.
Clean all dirt from the master cylinder filler cap, then remove the cap and fill the brake master cylinder reservoir with clean, specified brake fluid.
NOTEMaster cylinder pressure bleeder adapter tools are available from various manufacturers of pressure bleeding equipment. Follow the manufacturer's instructions 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.
Place a box-end wrench on the RH rear disc brake caliper bleeder screw. Attach a rubber hose to the RH rear disc brake caliper bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.
- Open the valve on the bleeder tank.
- Loosen the rear disc brake caliper bleeder screw. Leave the bleeder screw open until clear, bubble-free brake fluid flows into the container, then tighten the rear disc brake caliper bleeder screw and remove the rubber hose. Tighten to 8 Nm (71 inch lbs.).
- Continue bleeding the rest of the system, going in order from the LH rear disc brake caliper to the RH front disc brake caliper, ending with the LH front disc brake caliper.
- Close the bleeder tank valve and remove the tank hose from the adapter and remove the adapter.
- Fill the brake master cylinder reservoir with clean, specified brake fluid and install the cap.
