Solution

1. Preparation

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

2. Locate and Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the level against the minimum and maximum marks on the reservoir.
If the fluid is low, proceed to the next step.

3. Identify and Repair Leaks

Inspect brake lines, hoses, and connections for leaks.
If a leak is found, replace the damaged component (e.g., brake line or hose).
Tighten any loose fittings or connections.

4. Refill Brake Fluid

Use the appropriate type of brake fluid as specified in the owner's manual (usually DOT 3 or DOT 4).
Carefully remove the reservoir cap and add fluid until it reaches the maximum level.
Replace the cap securely.

5. Test Brake System

Start the vehicle and pump the brake pedal to build pressure.
Check for any leaks again after pumping the brakes.
Take the vehicle for a test drive to ensure proper brake function.
