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.
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 the hydraulic control unit (HCU) or master cylinder is disconnected for repair or installation of new components, air can get into the
system and cause spongy brake pedal action. This requires bleeding of the hydraulic system after it is correctly connected. The hydraulic system can
be bled manually or with pressure bleeding equipment.
NOTE: Pressure bleed the brake system at 207-345 kPa (30-50 psi).
NOTE: It is not necessary to do a complete brake system bleed if only the disc brake caliper was disconnected.
1. Clean all the dirt from around the brake fluid reservoir cap and remove the cap. Fill the brake master cylinder reservoir with clean, specified brake
fluid.
