Solution

1. Preparation

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

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 as specified in the owner's manual).

3. Examine for External Leaks

Inspect the master cylinder for any signs of brake fluid around its base and along the brake lines.
Clean any dirt or debris around the master cylinder with a cloth to see if fluid is seeping.

4. Check Brake Calipers and Wheel Cylinders

Remove the wheel to access the brake caliper.
Inspect the caliper for signs of fluid leakage from the seals.
Inspect the brake pads for excessive wear caused by fluid leaks.
If leaks are found, replace the affected caliper or wheel cylinder.

5. Inspect Brake Lines and Hoses

Follow the brake lines from the master cylinder to the wheels.
Look for any cracks, corrosion, or wear on the lines.
Replace any damaged lines with new brake lines, ensuring they are properly secured.

6. Perform Pressure Test

Use a brake pressure tester to check for leaks under pressure.
If the pressure drops, identify the source of the leak and repair or replace the faulty component.
