Solution

1. Preparation

Gather tools and materials:
- Brake fluid
- Wrench set
- Brake bleeder kit
- Clean cloths
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Inspect the brake fluid level. If low, add the specified type of brake fluid (DOT 3 or DOT 4).
Check for signs of contamination in the fluid.

3. Inspect and Repair Brake Lines

Use a wrench to check all brake line connections for tightness.
Look for corrosion or damage on the lines. Replace any damaged sections.
If leaks are found, replace the affected components.

4. Bleed the Brake System

Attach a brake bleeder kit to the brake bleeder valve on each wheel.
Start with the wheel farthest from the master cylinder (usually the right rear).
Open the bleeder valve and have an assistant pump the brake pedal until fluid flows without air bubbles. Close the valve and repeat for each wheel in the correct order (right rear, left rear, right front, left front).
Keep the master cylinder reservoir topped off during the process to prevent air from re-entering the system.

5. Inspect Brake Pads and Rotors

Remove the wheels using a socket set.
Inspect brake pads for wear; replace if they are below the manufacturer’s minimum thickness.
Check the rotors for scoring or warping. Resurface or replace as needed.

6. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Test the brake pedal feel before driving. Ensure it feels firm and responsive.
