Component Bleeding




Component Bleeding





Master Cylinder

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.

WARNING: Do not allow the brake master cylinder to run dry during the bleeding operation. Master cylinder may be damaged if operated without fluid, resulting in degraded braking performance. Failure to follow this instruction may result in serious personal injury.

NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water.

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.

Hybrid vehicles

1. Disconnect the brake tubes from the master cylinder.





2. Install short brake tubes onto the primary and secondary ports of the master cylinder with the ends submerged in the brake master cylinder reservoir.

3. Fill the brake reservoir with clean, specified brake fluid.

4. NOTE: On hybrid vehicles, the brake booster push rod has an elongated slot that attaches to the brake pedal with a clevis pin. The elongated slot allows for a small amount of pedal travel (free play) to occur without the brake pedal applying pressure on the booster push rod. When performing a bleed procedure, it is important to push the pedal through the air gap, so that the clevis pin is contacting the brake booster push rod. Except when required by the scan tool, the ignition key must remain off during the bleed procedure to allow minimal force required to push through the gap.

Have an assistant pump the brake pedal until clear fluid flows from both brake tubes, without air bubbles.





5. Remove the short brake tubes and install the brake outlet tubes.
- Tighten the master cylinder brake tube fittings to specifications. Refer to Specifications.

Non-hybrid vehicles

6. Place a box-end wrench on the master cylinder bleeder screw and attach a rubber drain hose to the bleeder screw. Submerge the free end of the rubber hose into the master cylinder reservoir.

7. Fill the master cylinder reservoir with clean, specified brake fluid.

8. Have an assistant pump the brake pedal until clear fluid flows from the rubber hose, without air bubbles.

9. Tighten the bleeder screw to specifications. Refer to Specifications. Remove the rubber hose and install the bleeder screw cap.

All vehicles

10. Bleed the brake system. For additional information, refer to Brake System Bleeding Brake System Bleeding.

Brake Caliper

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.

WARNING: Do not allow the brake master cylinder to run dry during the bleeding operation. Master cylinder may be damaged if operated without fluid, resulting in degraded braking performance. Failure to follow this instruction may result in serious personal injury.

NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water.

NOTE: It is not necessary to do a complete brake system bleed if only the brake caliper was disconnected or installed new.

1. Remove the bleeder screw cap and place a box-end wrench on the bleeder screw. Attach a rubber drain hose to the bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.





2. Have an assistant pump the brake pedal at least 2 times and then hold firm pressure on the brake pedal.

3. Loosen the 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.

4. Tighten the bleeder screw to specifications. Refer to Specifications. Remove the rubber hose and install the bleeder screw cap.





5. Apply brakes several times to verify correct brake operation.

Wheel Cylinder

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.

NOTICE: Do not spill brake fluid on painted or plastic surfaces or damage to the surface may occur. If brake fluid is spilled onto a painted or plastic surface, immediately wash the surface with water.

NOTE: It is not necessary to do a complete brake system bleed if only the wheel cylinder was disconnected or installed new.

1. Remove the bleeder screw cap and place a box-end wrench on the bleeder screw. Attach a rubber drain hose to the bleeder screw and submerge the free end of the hose in a container partially filled with clean, specified brake fluid.
