Solution

1. Preparation

Gather tools: socket set, brake line wrench, OBD-II scanner, brake fluid, and a vacuum pump.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Refill Brake Fluid

Open the hood and locate the master cylinder.
Remove the cap and check the fluid level; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for any signs of contamination in the fluid; if contaminated, a complete brake fluid flush is required.

3. Check for Leaks

Visually inspect all brake lines, calipers, and connections for signs of leaks.
If any leaks are found, replace the damaged components immediately.
If no leaks are found, proceed to check the brake lines for air.

4. Bleed the Brake System

Use a vacuum pump or helper to bleed the brakes.
Start with the wheel farthest from the master cylinder, typically the right rear.
- Attach the brake bleeder kit to the bleeder valve and open it while a helper presses the brake pedal.
- Close the valve when the pedal is fully depressed and repeat until no air bubbles are visible.
Move to the left rear, then right front, and finally left front, repeating the bleeding process.

5. Inspect Brake Components

Remove the wheels to access the brake pads and rotors.
Check the thickness of the brake pads and replace if they are worn below the minimum thickness.
Inspect rotors for warping or scoring, and replace if necessary.

6. Test Brake Booster

To check the brake booster, start the engine and press the brake pedal; it should feel firm.
If the pedal does not firm up, the brake booster may need to be replaced.
