Solution

1. Preparation

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

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the "MIN" and "MAX" marks on the reservoir.
If fluid is low, inspect for leaks before adding fluid.

3. Visual Inspection of Brake Lines and Components

Start at the master cylinder and trace the brake lines to the wheels.
Look for any signs of wet or discolored areas on the lines.
Check the brake calipers for any signs of fluid leakage where the caliper meets the brake line.

4. Inspect Wheel Areas

Remove the wheel on the side where a leak is suspected (if necessary).
Inspect the brake caliper and wheel cylinder for leaks.
Use a clean cloth to wipe any suspected areas to check for new fluid accumulation.

5. Clean and Repair

If a leak is found, clean the affected area and determine if the component (brake line, caliper, or master cylinder) needs to be replaced.
Replace any damaged or corroded parts using appropriate replacement components.

6. Refill Brake Fluid

If brake fluid was lost, refill it to the correct level in the reservoir using the recommended brake fluid type (DOT 3 or DOT 4, depending on specifications).
Ensure no air bubbles are introduced into the system.
