Solution

1. Preparation

Gather tools and materials:
- Safety glasses
- Clean rags or paper towels
- Brake fluid (if needed)
- Wrench set
- Flashlight for better visibility
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down if it has been running.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum markings.
If the fluid is low, use a clean rag to wipe the reservoir cap and remove it.
Add brake fluid if necessary, but do not overfill.

3. Check Brake Lines and Hoses

Visually inspect the brake lines leading from the master cylinder to the wheels.
Look for any signs of corrosion, cracks, or wetness.
Using a wrench, gently tighten any loose connections to prevent further leaks.

4. Inspect Brake Calipers

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

5. Inspect Master Cylinder

Check the master cylinder for signs of leakage or fluid accumulation.
If the master cylinder shows signs of failure, it will need to be replaced.
Ensure all connections to the master cylinder are secure.

6. Final Checks

After repairs, replace any removed components and wheels.
Refill the brake fluid reservoir to the appropriate level.
Start the vehicle and pump the brake pedal to ensure it feels firm.
