Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Brake Fluid Inspection

Tools Required: Brake fluid tester, funnel.
Check the brake fluid level in the reservoir; top off if low.
Inspect the fluid for contamination; if it appears dark or murky, replace it.

3. Inspect for Leaks

Tools Required: Flashlight.
Visually inspect all brake lines, calipers, and wheel cylinders for signs of leakage.
If any leaks are found, replace the affected component.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, brake fluid.
Start with the wheel furthest from the master cylinder (typically the rear passenger side).
Attach the bleeder kit to the bleeder valve, open it slightly, and have an assistant press the brake pedal several times until no air bubbles are present in the fluid.
Close the valve and repeat for all wheels in the correct order (rear passenger, rear driver, front passenger, front driver).
Ensure the brake fluid level does not drop too low during this process.

5. Replace Brake Fluid (if necessary)

Tools Required: Brake fluid, funnel.
If the fluid was contaminated or moisture content was high, fully flush the brake system with new brake fluid until it runs clear.
