Solution

1. Preparation

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

2. Tools and Parts Gathering

Tools Required:
- Brake fluid
- Brake bleeder kit (or a clear tube and container)
- Wrench set
- Funnel
- Jack and jack stands
- Torque wrench
Parts Required:
- New brake fluid (DOT 3 or DOT 4, as specified by the manufacturer)

3. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

4. Locate Brake Bleeder Screws

Identify the brake bleeder screws on each wheel's brake caliper (typically on the top of the caliper).

5. Flush the Brake Fluid

Remove Brake Fluid Reservoir Cap:
- Open the brake fluid reservoir cap and check the fluid level. Add fresh brake fluid if necessary to prevent air from entering the system during the flush.
Start with the Furthest Brake:
- Begin with the right rear wheel, then proceed to the left rear, right front, and finally the left front.
Attach Bleeder Hose:
- Place a clear hose over the bleeder screw and direct it into a container to catch old fluid.
Open Bleeder Screw:
- Use a wrench to slowly loosen the bleeder screw.
- Have an assistant press the brake pedal down and hold it.
Flush Old Fluid:
- As the pedal is pressed, old fluid will flow out through the hose.
- Monitor the fluid until it runs clear, indicating that new fluid is reaching the caliper.
- Tighten the bleeder screw before the brake pedal is released to avoid sucking air back into the system.
Repeat for Each Wheel:
- Repeat the process for each wheel in the order specified.

6. Final Steps

After flushing all wheels, top off the brake fluid reservoir.
Replace the reservoir cap securely.

7. Lower Vehicle

Remove the jack stands and lower the vehicle back to the ground.
