Solution

1. Preparation

Gather the necessary tools and safety equipment.
Ensure the vehicle is on a flat surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Locate and Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap and visually inspect the fluid level.
If the reservoir is low, proceed to check for leaks.

3. Inspect Brake Lines and Hoses

Follow the brake lines from the reservoir to the wheels.
Look for any signs of wetness, corrosion, or damage.
Tighten any loose fittings and replace damaged lines or hoses.

4. Check Calipers and Wheel Cylinders

Remove the wheel to access the brake components.
Inspect the brake calipers for any fluid leaks around the seals.
Check the wheel cylinder (if applicable) for fluid seepage and replace if necessary.

5. Examine the Master Cylinder

Inspect the master cylinder located near the brake fluid reservoir.
Check for leaks around the seals and connections.
If leaking, replace the master cylinder following manufacturer specifications.

6. Test and Refill Brake Fluid

After all inspections and repairs are complete, refill the brake fluid reservoir with the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Bleed the brake system if any components were replaced to ensure no air is trapped in the lines.
