Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Inspect the Brake Fluid Reservoir

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" lines.
Note the color of the fluid; it should be clear to light amber. Dark or contaminated fluid indicates issues.

3. Check for External Leaks

Visually inspect the brake lines from the master cylinder to the calipers for any signs of fluid leakage.
Look for wet spots, stains, or corrosion on the lines.
Examine the brake calipers for any signs of fluid seeping.

4. Inspect the Master Cylinder

Remove the cover of the master cylinder reservoir.
Check for any signs of fluid around the base of the master cylinder.
If fluid is present, the master cylinder may need replacement.

5. Pressure Test

Using a brake pressure tester, connect the tool to the brake system.
Pressurize the system and monitor for drops in pressure, which would indicate a leak.
If a leak is detected, further isolate the area (lines, calipers) to pinpoint the exact location.

6. Repair or Replace Affected Components

If leaks are found in brake lines, remove and replace the damaged sections.
For leaking calipers or master cylinders, remove and replace them with new units.
Ensure all connections are secure and properly torqued.
