Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear appropriate safety gear (gloves, goggles).

2. Inspect Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum marks.
If low, add the appropriate brake fluid (DOT 3 or DOT 4).

3. Check Brake Lines and Hoses

Follow the brake lines from the master cylinder to the calipers.
Look for cracks, abrasions, or bulges in the lines.
Inspect hose connections for secure fittings and signs of leaking.

4. Inspect Master Cylinder

Remove any covers obstructing the master cylinder.
Look for fluid leaks around the master cylinder seals.
If leaks are present, the master cylinder may need to be replaced.

5. Check Brake Calipers

Look for any wetness or fluid around the caliper seals.
If fluid is present, replace the caliper or repair the seals as necessary.

6. Inspect Brake Drums (if applicable)

If the vehicle has rear drum brakes, remove the drum.
Check for signs of brake fluid inside the drum.
Replace any contaminated brake components.
