Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves.

2. Locate and Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Clean the area around the reservoir cap to prevent contamination.
Remove the cap and check the fluid level against the minimum and maximum marks.

3. Check for Leaks

Visually inspect the brake lines for cracks or leaks.
Check around the brake calipers and wheel cylinders for signs of fluid leakage.
If any leaks are found, the affected component must be replaced.

4. Replace Brake Fluid

If the fluid is low but no leaks are found, top off the brake fluid using the manufacturer's recommended fluid type (usually DOT 4).
Be careful not to spill brake fluid, as it can damage paint and other surfaces.

5. Test Brake System

After topping off, pump the brake pedal several times to ensure proper fluid circulation.
Check the brake pedal feel; it should feel firm and responsive.

6. Reassemble and Clean

Replace the reservoir cap securely.
Clean any spilled brake fluid with a suitable brake cleaner.
