Solution

1. Preparation

Gather necessary tools and materials:
- Clean rag or paper towels
- New brake fluid (DOT 3 or DOT 4, as specified in the owner's manual)

2. Inspect and Clean

Wipe the area around the brake fluid reservoir with a clean rag to avoid contamination.
Remove the reservoir cap carefully by turning it counterclockwise to prevent dust and debris from entering the system.

3. Check Fluid Level

Inspect the fluid level against the minimum and maximum markings on the reservoir.
If the fluid is low, proceed to add new brake fluid.

4. Add Brake Fluid

Using a funnel, add the appropriate brake fluid until it reaches the maximum level mark.
Avoid overfilling, as it can lead to fluid overflow when the brakes are used.

5. Reattach Reservoir Cap

Securely place the reservoir cap back on by turning it clockwise until it is fully seated.
Ensure it is tight to prevent contamination.

6. Clean Up

Wipe any spilled fluid from the area around the reservoir.
Dispose of any used materials according to local regulations.
