Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles.

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level; if it’s low, this may indicate a leak.
If necessary, top off the fluid with the correct type (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for any signs of corrosion, cracks, or dampness on the lines.
If leaks are found, mark the locations for repair or replacement.

4. Check Brake Calipers and Wheel Cylinders

For each wheel, remove the wheel to gain access to the brake calipers.
Inspect the calipers for any signs of fluid leaking from the seals.
Examine the wheel cylinders (if applicable) for signs of brake fluid leakage.
Replace any leaking calipers or cylinders as necessary.

5. Inspect Master Cylinder

Locate the master cylinder, typically near the brake fluid reservoir.
Check around the master cylinder for any signs of leakage.
If leaks are present, replace the master cylinder.

6. Test the System

After repairs, bleed the brake system to remove air bubbles.
Recheck the brake fluid level and top off if needed.
