Solution

1. Preparation

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

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the minimum and maximum marks.
If low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Examine Brake Lines and Hoses

Follow the brake lines from the master cylinder to each wheel.
Look for cracks, fraying, or signs of corrosion.
If leaks are found, proceed to replace the affected line or hose.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel to access the brake calipers or drum brakes.
Inspect the caliper for wetness or fluid residue.
If leaking, replace the caliper or wheel cylinder as necessary.

5. Tighten Connections

Inspect all connections and fittings for tightness.
Use a wrench to tighten any loose fittings around the brake lines, calipers, or master cylinder.

6. Test the Brake System

After repairs, pump the brake pedal several times to build pressure.
Check for leaks again while someone else presses the brake pedal.
