Master Cylinder Priming - 3.8L

For in-vehicle priming, disconnect the brake lines. For bench priming, mount the brake master cylinder in a vise.
On all applications, install short brake tubes with the 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.
Have an assistant pump the brake pedal, or slowly depress the primary piston until clear fluid flows from both brake tubes, without air bubbles.
If the brake master cylinder has been primed at the bench, install it in the vehicle.
On all applications, 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, and then hold firm pressure on the brake pedal.
- Loosen the rear most brake tube fittings 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.
