Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake pad spreader, brake cleaner, and safety glasses.
Ensure the vehicle is on a flat surface, and set the parking brake.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts slightly on the wheels.
Raise the vehicle using the jack and secure it with jack stands. Ensure the vehicle is stable before proceeding.

3. Remove the Front Wheels

Fully remove the lug nuts and take off the front wheels to access the brake components.

4. Inspect the Brake System

Brake Pads and Rotors:
- Check the brake pads for uneven wear. Replace if they are worn down more on one side.
- Inspect the rotors for warping or scoring. Resurface or replace as needed.
Brake Calipers:
- Check for proper operation. Ensure the caliper slides freely and is not stuck.
- If the caliper is sticking, consider rebuilding or replacing it.

5. Check Brake Lines

Inspect the brake lines for any signs of leaks, damage, or blockages. Replace any damaged lines.

6. Inspect Suspension Components

Examine the control arms, bushings, and tie rods for wear and proper alignment.
Replace any worn or damaged parts to ensure proper handling.

7. Reassemble and Lower the Vehicle

Reinstall the wheels, tightening the lug nuts to the manufacturer’s specified torque.
Lower the vehicle and remove the jack stands.
