Removal And Installation

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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: 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 installing a new ABS module/hydraulic control unit (HCU) assembly, it must be configured (either by download/upload or uploading the as-built data method).

NOTE: On vehicles equipped with roll stability control (RSC), the ABS module is available separately from the HCU and should be serviced separately. However, if the RSC equipped vehicle requires a new HCU, then the ABS module and the HCU must be installed as an assembly. Make sure to use the most recently released service parts.
