Solution

1. Preparation

Gather tools and materials needed for inspection.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles for protection.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it is below the minimum mark, this indicates a potential leak.
Clean the exterior of the reservoir with a cloth to prevent contamination.

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Inspect for any signs of wear, cracks, or corrosion.
If damage is found, proceed to replace the affected lines or hoses.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel to gain access to the brake calipers.
Inspect calipers for fluid seepage around the piston seals.
If leaking, replace the caliper with a new unit.

5. Inspect Master Cylinder

Check for leaks around the master cylinder, particularly at the mounting points and seal areas.
If leaks are detected, replace the master cylinder.

6. Refill Brake Fluid

If any fluid was lost during inspection, refill with the appropriate brake fluid type (DOT 3 or DOT 4 as specified).
Bleed the brake system if air was introduced during the inspection.
