Solution

1. Preparation

Gather tools and materials: an OBD-II scanner, a wrench set, brake fluid (DOT 3 or DOT 4), a clean rag, and a container for fluid collection.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake for safety.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, usually found near the back of the engine bay.
Remove the cap and check the fluid level against the markings on the reservoir.
- If low, proceed to the next steps; if adequate, inspect for leaks.

3. Inspect for Leaks

Visually inspect all brake lines, calipers, and the master cylinder for signs of fluid leaks.
Clean any dirt or debris from the area to make leaks easier to identify.
If leaks are found, replace the affected components (e.g., brake lines, calipers, or master cylinder).

4. Add Brake Fluid

If the fluid is low and no leaks are detected, add the appropriate brake fluid (DOT 3 or DOT 4) until the proper level is reached.
Replace the reservoir cap securely after adding fluid.

5. Bleed Brake System (if necessary)

If air is suspected in the system due to low fluid levels, bleed the brake lines.
Start with the brake furthest from the master cylinder and work toward the closest.
- Attach a clear tubing to the bleeder screw and place the other end into a container.
- Have an assistant pump the brake pedal several times and hold it down.
- Open the bleeder screw to release air and fluid, then close it before your assistant releases the brake pedal.
- Repeat until no air bubbles are visible in the tubing.
