Solution

1. Preparation

Gather tools such as a wrench set, brake bleeder kit, and a container for old brake fluid.
Ensure the vehicle is parked on a level surface and engaged in park (or neutral for manual transmission).
Wear safety goggles and gloves to protect against brake fluid.

2. Inspect Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the reservoir cap and check the brake fluid level.
If low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4) to the proper level.

3. Check for Leaks

Visually inspect brake lines, hoses, and calipers for any signs of fluid leakage.
If leaks are found, replace the damaged components (hoses, lines, or calipers) as necessary.

4. Bleed the Brake System

Attach a brake bleeder kit to the brake bleeder valve on each brake caliper.
Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
Close the valve before the pedal is fully depressed to avoid drawing air back in.
Repeat this process for all four wheels until clear fluid without air bubbles is seen.
Ensure to keep the master cylinder reservoir topped up during this process to prevent air from entering the system.

5. Inspect and Replace Master Cylinder (if necessary)

If the issue persists after bleeding, remove the master cylinder.
Inspect for internal damage or fluid leaks.
If damaged, replace the master cylinder with a new OEM part.
Follow manufacturer specifications for installation and torque values.
