Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and eyewear for protection.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level against the minimum and maximum marks.
If low, proceed to identify the leak source.

3. Check for Leaks

Visually inspect all brake lines for cracks or corrosion.
Check connections at the master cylinder and brake calipers for signs of fluid.
If leaks are found, mark the locations for repair.

4. Repair Leaks

If a brake line is damaged, use a line wrench to disconnect it from the fittings.
Replace with a new brake line and ensure all connections are tight.
If calipers or the master cylinder are leaking, replace them as necessary.

5. Refill Brake Fluid

After repairs, refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
Be careful not to overfill the reservoir.

6. Bleed Brake System (if necessary)

If air has entered the system, bleed the brake lines using a brake bleeder kit or two-person method.
Ensure that the brake fluid reservoir is kept filled during this process.

7. Final Inspection

Double-check all connections and fluid levels.
Replace the reservoir cap securely.
