Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Wrench set
- Brake fluid (DOT 4)
- Brake cleaner
- Rags for cleanup
Safety Warnings:
- Ensure the vehicle is on a flat surface, and use wheel chocks.
- Wear gloves and safety goggles to protect against brake fluid.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the "MIN" and "MAX" marks.
If the fluid is low, add the appropriate brake fluid (DOT 4) and check for leaks afterward.

3. Check Brake Lines and Hoses

Visually inspect the entire length of the brake lines and hoses for any signs of wetness or fluid stains.
Look for cracks, abrasions, or corrosion on the lines.

4. Inspect Brake Calipers

Remove the wheel to gain access to the brake caliper.
Check around the caliper for any signs of fluid leakage.
If fluid is present, the caliper may need to be replaced or rebuilt.

5. Examine Master Cylinder

Locate the master cylinder, typically found near the brake booster.
Check for any fluid around the base or on the sides.
If leaking, replace the master cylinder.

6. Tighten Connections

Inspect all connections between the brake lines and calipers.
Ensure all fittings and connections are tight and secure.
If leaks persist, consider replacing the affected lines or fittings.
