Solution

1. Preparation

Tools Required: Brake fluid vacuum bleeder, wrench set, clean rags, container for old fluid, funnel.
Sub-steps:
1. Park the Tesla Model Y on a level surface and activate the parking brake.
2. Locate the brake fluid reservoir (typically near the driver's side near the back of the engine compartment).
3. Wear safety gloves and goggles to protect against brake fluid.

2. Remove Old Brake Fluid

Sub-steps:
1. Using the vacuum bleeder, connect the adapter to the brake fluid reservoir.
2. Activate the vacuum bleeder to extract the old brake fluid from the reservoir.
3. Dispose of the old brake fluid properly according to local regulations.

3. Add New Brake Fluid

Sub-steps:
1. Using a funnel, pour new brake fluid (consult the owner's manual for the recommended type, usually DOT 3 or DOT 4) into the reservoir until it reaches the maximum fill line.
2. Replace the reservoir cap securely.

4. Bleed the Brake Lines

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually the right rear wheel).
2. Loosen the bleeder screw on the brake caliper using a wrench.
3. Connect the vacuum bleeder to the bleeder screw and activate it to draw out old fluid until new fluid flows through the line.
4. Tighten the bleeder screw while the vacuum is still applied.
5. Repeat the process for the left rear, right front, and finally the left front wheels.

5. Final Check

Sub-steps:
1. Inspect all bleeder screws to ensure they are tight.
2. Clean any spilled brake fluid from the vehicle components.
3. Perform a final check of the brake fluid level in the reservoir and top off if necessary.
