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.
CAUTION:
Do not allow the brake master cylinder reservoir to 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 or damage to the brake system components may occur.
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 any part of the hydraulic system has been disconnected for repair or new installation, air may get into the system and cause spongy brake pedal action. 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.
NOTE:
When the brake master cylinder has been replaced or the system has been emptied, or partially emptied, it should be primed to prevent air from entering the system.
- Disconnect the brake tubes from the master cylinder.
- Install short brake tubes with the 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 at least 2 times and then hold firm pressure on the brake pedal.
- Loosen the rearmost brake tube fitting until a stream of brake fluid comes out. While the assistant maintains pressure on the brake pedal, tighten 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.
- Tighten the brake tube fittings to 18 Nm (13 lb-ft).
- Bleed the brake system, refer to Manual or Pressure Bleeding Methods.
