Solution

1. Preparation

Gather necessary tools and parts.
Safely lift the vehicle using a jack and secure with jack stands.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the front wheel using a socket set.
- Unbolt the caliper and suspend it using a wire to avoid stress on the brake line.
- Remove the brake rotor by unscrewing the retaining screws and gently pulling it off.
- Inspect for warping using a dial gauge; replace if warped beyond specifications (typically 0.002 inches).
- Install new rotors, ensuring proper alignment and torque to manufacturer specifications (usually around 90-100 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Inspect pads for even wear; replace if they are below the minimum thickness (usually 3 mm).
- Apply brake grease to the backing of new pads and install them into the caliper bracket.

4. Check and Replace Suspension Components

Sub-steps:
- Inspect control arms and bushings for cracks or excessive wear.
- Replace any worn components with OEM parts, ensuring proper torque specifications (consult service manual).

5. Perform Wheel Balancing

Sub-steps:
- Remove the wheel and take it to a tire shop for balancing.
- Reinstall the wheel after balancing, ensuring lug nuts are torqued to specifications (usually 120 Nm).
