Solution

1. Preparation

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

2. Gather Tools and Parts

Tools Required:
- Brake bleeder kit or vacuum bleeder
- Wrench set (for bleeder screws)
- Turkey baster or fluid siphon
- Clean rags or shop towels
- Container for old brake fluid
Parts Required:
- New brake fluid (refer to owner's manual for specification, typically DOT 3 or DOT 4)

3. Remove Old Brake Fluid

Open the hood and locate the brake fluid reservoir.
Use a turkey baster or siphon to remove as much old brake fluid from the reservoir as possible.
Wipe the reservoir cap and surrounding area clean to prevent contamination.

4. Introduce New Brake Fluid

Fill the brake fluid reservoir with new brake fluid up to the "MAX" line.
Ensure the cap is securely closed to prevent moisture contamination.

5. Bleed the Brakes

Start at the wheel farthest from the master cylinder (usually the right rear).
Attach a clear tube to the bleeder screw on the brake caliper and place the other end in a container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw with a wrench to let fluid escape until it runs clear, then close the screw.
Instruct the assistant to release the brake pedal.
Repeat the process until clear, bubble-free fluid is seen, then move to the next wheel (left rear, right front, left front).
Check the fluid level in the reservoir frequently and top off as necessary.

6. Final Checks

Once all wheels are bled, check the brake fluid reservoir level and top off if necessary.
Ensure all bleeder screws are tightened.
Clean up any spilled brake fluid immediately, as it can damage paint and surfaces.
