Solution

1. Preparation

Tools Required: Clean cloth or paper towel.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear gloves to prevent skin contact with brake fluid.

2. Inspect the Brake Fluid Level

Open the brake fluid reservoir cap slowly to avoid any spills.
Using a clean cloth, wipe the exterior of the reservoir cap to prevent dirt from entering the reservoir.
Visually check the fluid level against the MIN and MAX markings on the reservoir. If the fluid is below the MIN mark, it needs to be topped off.

3. Top Off Brake Fluid (if necessary)

Parts Required: Brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Using a funnel, carefully add the appropriate brake fluid until it reaches the MAX level. Do not overfill.
Replace the reservoir cap securely.
Clean up any spilled brake fluid immediately, as it can damage paint and other surfaces.

4. Check for Leaks

After topping off the fluid, inspect the brake lines and connections for leaks.
If there are any signs of leakage, further investigation and repair may be necessary.
