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.
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.
Performing 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.
Add clean, specified brake fluid as necessary throughout the procedure.
When a new brake master cylinder has been installed or the system has been emptied, or partially emptied, it should be primed to prevent air from getting into the system.
Disconnect the brake master cylinder outlet tubes.

Install short brake tubes with ends submerged in the brake master cylinder reservoir and fill the brake master cylinder reservoir with clean, specified brake fluid.
Have an assistant pump the brake pedal until clear fluid flows from both brake tubes without air bubbles.
Remove the short brake tubes and install the brake outlet tubes.
Bleed each brake tube at the brake master cylinder as follows:
Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
Loosen the rearmost brake tube fittings until a stream of brake fluid comes out. Have an assistant maintain pressure on the brake pedal while tightening the brake tube fitting.
Repeat this operation until clear, bubble-free fluid comes out.
Refill the brake master cylinder reservoir as necessary. Repeat the bleeding operation at the front brake tube.
While the assistant maintains pressure on the brake pedal, tighten the brake tubes to 28 Nm (21 ft. lbs.).
