Solution

1. Preparation

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

2. Locate the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir, typically found near the back of the engine bay, attached to the master cylinder.
Clean the area around the reservoir cap to prevent debris from entering.

3. Check and Refill Brake Fluid

Remove the reservoir cap carefully.
Using a clean funnel, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual) until it reaches the "Full" mark.
Avoid overfilling the reservoir.

4. Inspect and Repair Leaks

If leaks are detected during inspection, tighten any loose fittings or replace damaged brake lines, calipers, or the master cylinder as necessary.
Use a brake line flaring tool and proper seals if replacing lines.

5. Bleed the Brake System (if necessary)

If air has entered the brake lines, bleed the brake system:
- Start with the wheel farthest from the master cylinder (usually the rear passenger side).
- Connect a clear tubing to the bleeder valve on the brake caliper and place the other end in a container.
- Open the bleeder valve and press the brake pedal until fluid flows out without air bubbles, then close the valve.
- Repeat for all wheels in the correct order (rear passenger, rear driver, front passenger, front driver).

6. Final Checks

Recheck the brake fluid level after bleeding and top off if necessary.
Replace the reservoir cap securely.
Test the brake pedal feel by pressing it several times to ensure proper operation.
