Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety gloves and goggles.

2. Inspect 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 until it reaches the appropriate level.

3. Visual Inspection of Brake Lines

Examine all visible brake lines for any signs of damage, corrosion, or fluid residue.
Use a flashlight if necessary to see hard-to-reach areas.
Replace any damaged lines with OEM parts if leaks are found.

4. Check Brake Calipers and Wheel Cylinders

Inspect each brake caliper and wheel cylinder for signs of leakage.
Look for wetness or fluid around the seals and connections.
If leaks are detected, replace the affected caliper or wheel cylinder.

5. Examine Master Cylinder

Locate the master cylinder, usually mounted on the brake booster.
Check around the master cylinder for any signs of leakage.
If there is evidence of fluid seeping out, replace the master cylinder.

6. Pressure Test

Connect a brake system pressure tester to the brake system.
Pump the system to the recommended pressure (consult service manual for specifics).
Monitor the pressure gauge for any drops, indicating a leak.
Address any leaks found by repairing or replacing the affected components.
