Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear protective gloves and eyewear.

2. Inspect and Address Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if low, fill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated or discolored, proceed to a complete fluid flush.

3. Check for Leaks

Visually inspect all brake lines, calipers, and the master cylinder for signs of leaking fluid.
If leaks are found, replace the damaged components (e.g., brake lines, calipers).
Use a wrench to tighten any loose fittings.

4. Bleed the Brake System

Attach a brake bleeder kit to the brake bleeder valve on the farthest brake caliper from the master cylinder.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close the valve before your assistant releases the pedal.
Repeat this process until no air bubbles are seen in the fluid and fluid runs clear.
Move to the next calipers in order (farthest to closest to the master cylinder) and repeat.

5. Test the Brake System

After bleeding, check the brake pedal feel.
Conduct a test drive in a safe area to ensure brakes are functioning properly.
Monitor for any signs of sponginess or leaks.
