Solution

1. Preparation

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

2. Gather Tools and Parts

Tools Required:

Brake fluid (DOT 4)
Brake bleeder kit or clear hose
Wrench set
Vacuum pump (optional)
Torque wrench

Parts Required:

New brake fluid (DOT 4)

3. Remove Old Brake Fluid

Open the hood and locate the brake fluid reservoir.
Use a turkey baster or siphon to remove old brake fluid from the reservoir.
Clean the reservoir cap and area to prevent contamination.

4. Bleed the Brake System

Connect the Bleeder Kit:
- Attach the clear hose from the bleeder kit to the brake caliper bleeder screw.
- Ensure the hose is placed into a container to catch old fluid.
Bleed Each Brake:
- Begin with the brake furthest from the master cylinder (usually the right rear).
- Have an assistant press the brake pedal several times and hold it down.
- Open the bleeder screw with a wrench to release fluid and air, then close it while your assistant keeps the pedal down.
- Repeat this process until clear fluid is seen without bubbles, refilling the reservoir as necessary.
- Move to the next brake in this order: left rear, right front, and finally left front.

5. Finalize and Check

After all brakes are bled, ensure the reservoir is filled to the correct level.
Tighten all bleeder screws to the specified torque (usually around 7-10 Nm).
Replace the reservoir cap securely.
