Solution

1. Preparation

Tools Required: Basic hand tools, brake fluid, vacuum gauge, OBD-II scanner
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Check Brake Fluid

Inspect the brake fluid reservoir; if the fluid is low, refill it with manufacturer-recommended brake fluid.
If the fluid is contaminated, proceed to replace it.

3. Inspect Brake Booster

Locate the brake booster and check for any cracks or damage.
Disconnect the vacuum line from the brake booster.
Use a vacuum gauge to test the booster; it should hold vacuum. If not, replace the brake booster.

4. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads for thickness; replace if worn below 1/8 inch.
Check rotors for warping or scoring; replace if necessary.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Test the brake pedal for proper feel and function.
