2. Use a turkey baster or siphon to remove the old, contaminated brake fluid from the reservoir.
3. Dispose of the old brake fluid according to local regulations.

3. Flush the Brake System

Sub-steps:
1. Attach a clear hose to the bleeder valve on one of the brake calipers.
2. Have an assistant pump the brake pedal several times and hold it down.
3. Open the bleeder valve to allow old fluid and air to escape, then close the valve before the pedal is released.
4. Repeat until clean brake fluid flows from the bleeder valve.
5. Ensure to refill the reservoir with new brake fluid during this process to prevent it from running dry.

4. Replace Brake Fluid

Sub-steps:

2. Check the fluid level and ensure it reaches the maximum fill line.

5. Test the Brakes

Sub-steps:
1. Start the vehicle and press the brake pedal several times to ensure proper brake feel.
2. Perform a test drive at low speeds to confirm braking functionality and check for any unusual noises.
