Solution

1. Preparation

Tools Required: Jack stands, lug wrench, brake cleaner, torque wrench, OBD-II scanner.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery for safety while working on the braking system.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using the lug wrench.
3. Inspect the brake rotor for signs of warping or uneven wear.
4. If warped, remove the caliper by loosening the caliper bolts and hanging it securely (do not let it dangle on the brake line).
5. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
6. Install the new rotor, ensuring it is properly seated against the hub.
7. Reinstall the caliper and torque the caliper bolts to manufacturer specifications (typically 25-30 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; replace if they are below the minimum thickness (usually 3 mm).
2. Remove the old brake pads from the caliper bracket.
3. Apply brake lubricant to the backing of the new pads to prevent noise.
4. Install the new brake pads into the caliper bracket.

4. Examine Suspension Components

Sub-steps:
1. Visually inspect the control arms, bushings, and tie rods for signs of wear or damage.
2. Push and pull on the components to check for excessive play.
3. Replace any worn components as necessary.

5. Tire Balancing and Alignment

Sub-steps:
1. Remove the wheels and take them to a tire shop for balancing.
2. Perform a wheel alignment to ensure proper handling and tire wear.
