Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and is in "Park" mode.
Wear safety gloves and goggles.

2. Gather Tools and Materials

Tools Required:
- Brake fluid (DOT 3 or DOT 4 compatible with Tesla specifications)
- Brake bleeder kit or vacuum pump
- Wrench set (for brake bleeder screws)
- Funnel
- Clean rags
- Container for old brake fluid
- Safety gloves and goggles

3. Remove Old Brake Fluid

Use a syringe or turkey baster to remove old brake fluid from the reservoir.
Dispose of the old fluid properly in accordance with local regulations.

4. Refill with New Brake Fluid

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

5. Bleed the Brakes

Start with the wheel farthest from the master cylinder (typically the right rear wheel).
Locate the brake bleeder screw on the brake caliper.
Attach the brake bleeder kit or vacuum pump to the bleeder screw.
Open the bleeder screw while monitoring the fluid coming out, ensuring no air bubbles are present.
Close the bleeder screw once fluid runs clear and free of bubbles.
Repeat the process for the left rear, right front, and then left front wheels in that order.

6. Final Check

Inspect the brake fluid level in the reservoir.
Ensure all bleeder screws are tightly closed.
Clean any spills with a rag to prevent damage to vehicle components.

7. Test Drive

Conduct a short test drive to ensure proper brake function.
Monitor for any unusual sounds or warning lights.
