Motorcraft® High Performance DOT 3 Motor Vehicle Brake Fluid (US) / Motorcraft® Brake Fluid - Heavy Duty DOT 3 (Canada) PM-1-C (US); CPM-1-C (Canada) WSS-M6C62-A or WSS-M6C65-A1

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 the brake master cylinder has been installed new or the system has been emptied or partially emptied, it must be primed to prevent air from entering the system.

  1. Disconnect the brake outlet tubes from the master cylinder.
  1. Install short brake tubes onto the primary and secondary ports with the ends submerged in a container partially filled with clean, specified brake fluid.

  1. Have an assistant pump the brake pedal until clear fluid flows from the brake tubes without air bubbles.
  1. Remove the short brake tubes, and install the master cylinder brake tubes.
    • Tighten the brake tube fittings to specifications. Refer to Specifications in this section.
  1. Bleed the brake system. For additional information, refer to Brake System Bleeding in this section.

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.

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.

  1. Have an assistant pump the brake pedal at least 2 times and then hold firm pressure on the brake pedal.
  1. 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.
  1. Tighten the bleeder screw to specifications. Refer to Specifications in this section. Remove the rubber hose and install the bleeder screw cap.

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.
