Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel using a jack and a socket set.
- Inspect brake pads for thickness; replace if below manufacturer specifications (usually 3mm).
- Use a brake cleaner to clean the brake caliper and rotor.
- Reinstall new brake pads (ensure proper orientation) and reassemble the wheel.
Tools Required: Jack, jack stands, socket set, torque wrench, brake cleaner.

3. Check and Replace Brake Rotors

Sub-steps:
- If rotors are warped, remove the caliper and rotor.
- Measure rotor thickness with a micrometer; replace if below specifications.
- Install new rotors, ensuring they are torqued to manufacturer specifications.
Tools Required: Micrometer, brake rotor tool, torque wrench.

4. Wheel Alignment and Balancing

Sub-steps:
- Take the vehicle to a certified alignment shop.
- Request a four-wheel alignment and balancing service.
- Ensure all specifications are within manufacturer limits.
Tools Required: Alignment machine (performed by a professional).

5. Inspect Suspension Components

Sub-steps:
- Check for any damaged or worn shocks, struts, and bushings.
- Replace any faulty components as necessary.
Tools Required: Wrench set, possibly a spring compressor for struts.
