Solution

1. Preparation

Tools Required:
- Brake bleeder kit
- Wrench set
- Clean cloths
- Container for old fluid
- Safety glasses and gloves
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves to protect against brake fluid.

2. Access Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and inspect the fluid level and condition.

3. Drain Old Brake Fluid

Locate the brake bleeder valve on each brake caliper (starting with the wheel farthest from the master cylinder).
Attach a hose from the bleeder valve to a container to catch old fluid.
Use a wrench to open the bleeder valve slightly (about 1/4 turn).
Have an assistant press the brake pedal several times until old fluid is expelled, then close the valve before the pedal is released.
Repeat for all four wheels, ensuring to keep the brake fluid reservoir topped up with fresh fluid during the process.

4. Fill with New Brake Fluid

Clean the brake fluid reservoir again and fill it with the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4 for Toyota).
Ensure the fluid reaches the "MAX" line on the reservoir.

5. Bleed the Brake System

Begin with the wheel farthest from the master cylinder and repeat the bleeding process for each caliper.
After all calipers have been bled, check the fluid level in the reservoir and top up if necessary.
Make sure all bleeder valves are securely closed.

6. Final Checks

Replace the brake fluid reservoir cap securely.
Inspect the brake system for any leaks.
Dispose of the old brake fluid properly as it is toxic.
