Master Cylinder, In Vehicle
WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush
eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately.
CAUTION: Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with the specified
brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system.
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.
1. NOTE: When a new brake master cylinder has been installed or the system has been emptied, or partially emptied, it should be primed to prevent air from getting into the system.
Disconnect the brake master cylinder outlet tubes.
2. Install short brake tubes with ends submerged in the brake master cylinder reservoir and fill the brake master cylinder reservoir with High Performance DOT 3 Brake Fluid C6AZ-
19542-AB or equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A.
3. Have an assistant pump the brake pedal until clear fluid flows from both brake tubes without air bubbles.
4. Remove the short brake tubes and install the brake outlet tubes.
5. Bleed each brake tube at the brake master cylinder as follows:
1. Have an assistant pump the brake pedal and then hold firm pressure on the brake pedal.
2. Loosen the rearmost brake tube fittings until a stream of brake fluid comes out. Have an assistant maintain pressure on the brake pedal while tightening the brake tube fitting.
3. Repeat this operation until clear, bubble-free fluid comes out.
4. Refill the brake master cylinder reservoir as necessary. Repeat the bleeding operation at the front brake tube.
6. While the assistant maintains pressure on the brake pedal, tighten the brake tubes.
