Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles to protect against fluid exposure.

2. Locate Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir, typically found near the back of the engine bay on the driver's side.
Clean the area around the reservoir cap to prevent contamination.

3. Remove Old Brake Fluid

Using a turkey baster or a siphon pump, extract as much old brake fluid from the reservoir as possible.
Dispose of the old fluid in accordance with local regulations.

4. Add New Brake Fluid

Fill the reservoir with new brake fluid that meets Ford specifications (DOT 3 or DOT 4).
Avoid overfilling; fill to the "MAX" line indicated on the reservoir.

5. Bleed the Brake System

Start at the wheel furthest from the master cylinder (passenger rear), then move to the driver rear, passenger front, and finish with the driver front.
For each wheel:
1. Attach a clear plastic hose to the bleeder valve on the brake caliper.
2. Place the other end of the hose into a container to catch old fluid.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to release fluid and air, then close it before the pedal is released.
5. Repeat until clear fluid without bubbles flows through the hose.
6. Tighten the bleeder valve and repeat for all wheels.
Ensure the brake fluid reservoir remains filled during this process.

6. Final Checks

After bleeding all brakes, check the fluid level in the reservoir and top off as necessary.
Replace the cap securely on the brake fluid reservoir.
