Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is parked on a level surface and the engine is off.
Place wheel chocks behind the rear wheels for safety.

2. Brake Fluid Inspection

Remove the master cylinder cap and check the brake fluid level.
If the fluid is low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 depending on specifications).
Inspect the fluid for contamination or dark color.

3. Inspect Brake Lines and Components

Visually inspect the brake lines, calipers, and master cylinder for any signs of leakage.
If leaks are found, replace affected components (e.g., brake lines, calipers).
Tighten any loose connections or fittings if necessary.

4. Bleed the Brake System

Attach a clear plastic tube to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow air and fluid to escape; close the valve before the pedal is released.
Repeat this process until no air bubbles are seen in the fluid.
Ensure the master cylinder reservoir remains filled during this process.

5. Test Brake System

Reassemble all components and replace the master cylinder cap.
Start the vehicle and press the brake pedal to check for firmness.
Perform a test drive to verify the brakes engage properly and the pedal feels solid.
