Solution

1. Preparation

Gather tools and materials.
Tools Required:
- Brake fluid
- Wrench set
- Brake bleeder kit
- Multimeter
- Jack and jack stands
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; add brake fluid if it is low.
If fluid is contaminated or dirty, proceed to replace it.

3. Bleed the Brake System

Step 1: Position the vehicle on jack stands and remove the wheel.
Step 2: Locate the brake bleeder valve on each caliper.
Step 3: Attach the brake bleeder kit to the valve and open it slightly.
Step 4: Pump the brake pedal several times until a steady stream of brake fluid is observed, ensuring no air bubbles are present.
Step 5: Close the bleeder valve and repeat for all calipers, starting from the farthest (right rear) to the nearest (left front).
Ensure to keep the brake fluid reservoir topped off during the process.

4. Inspect and Replace Components

Step 1: Check brake pads for wear and replace if the thickness is below the manufacturer's specification (typically 3mm).
Step 2: Inspect rotors for warping or scoring; replace if necessary.
Step 3: Examine the brake booster for any signs of leaks or failure; replace if defective.

5. Final Assembly

Reinstall the wheels and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications.
Dispose of old brake fluid and worn components in accordance with local regulations.
