Solution

1. Preparation

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

2. Inspect Brake Fluid Reservoir

Remove the cap from the brake fluid reservoir.
Check for cracks or damage to the reservoir.
If damaged, replace the reservoir.

3. Check Brake Lines and Hoses

Visual inspection of all brake lines and hoses.
Look for any signs of fluid leakage or corrosion.
If leaks or damage are found, replace the affected brake line or hose.

4. Inspect Brake Calipers and Wheel Cylinders

Remove the wheel to access the brake caliper.
Check for any fluid leaking from the caliper or wheel cylinder.
If leaking, replace the caliper or wheel cylinder as necessary.

5. Examine Master Cylinder

Locate the master cylinder and inspect for leaks at the base and along the fluid lines.
If leaks are present, replace the master cylinder.

6. Bleed Brake System (if necessary)

If brake fluid was lost due to leaks, bleeding the brakes may be necessary.
Use a brake bleeder kit or perform manual bleeding with an assistant.
Ensure all air is removed from the brake lines.
