2. Inspect the Brake Fluid Reservoir

Locate the brake fluid reservoir cap and carefully remove it.
- Safety Warning: Avoid allowing any contaminants to enter the reservoir.

Visually inspect the fluid level:
- The fluid should be between the minimum and maximum markings on the side of the reservoir. If it is below the minimum line, it requires topping off.
