Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and turn off the engine.
Wear safety glasses and gloves.

2. Remove Old Brake Fluid

Access Brake Fluid Reservoir:
- Open the hood and locate the brake fluid reservoir.
- Remove the cap carefully to avoid contamination.
Remove Old Fluid:
- Use a turkey baster or siphon pump to extract old brake fluid from the reservoir.
- Dispose of the old brake fluid properly.

3. Flush the Brake System

Locate Brake Bleeder Valves:
- Identify the brake bleeder valves on each brake caliper (front and rear).
Attach Hose and Collect Fluid:
- Attach a clear plastic hose to the bleeder valve and place the other end in a container to catch the fluid.
Bleed the Brakes:
- Have an assistant pump the brake pedal several times and hold it down.
- Open the bleeder valve to allow fluid and air to escape, then close it before the pedal is released.
- Repeat until clear fluid emerges, checking the reservoir frequently to ensure it does not run dry.
- Repeat this process for each brake caliper, starting from the brake furthest from the master cylinder (usually the passenger rear, then driver rear, passenger front, and driver front).

4. Add New Brake Fluid

Fill Reservoir:
- Fill the brake fluid reservoir with new DOT 3 or DOT 4 brake fluid, ensuring it meets the manufacturer specifications.
Check for Leaks:
- Inspect all connections and components for leaks after filling.

5. Final Steps

Reinstall Reservoir Cap:
- Secure the brake fluid reservoir cap tightly.
Test Brake Pedal:
- Firmly press the brake pedal to ensure it feels solid.
Dispose of Old Brake Fluid:
- Properly dispose of the old brake fluid in accordance with local regulations.
