Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather all necessary tools and parts.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the brake components.
- Inspect the rotors for any signs of warping or uneven wear using a dial gauge.
- If rotors are warped, use a rotor removal tool to detach them from the hub.
- Install new rotors, ensuring they are properly torqued to manufacturer specifications.

3. Check and Replace Brake Pads

Sub-steps:
- With the rotor removed, inspect the brake pads for thickness and wear.
- Replace pads if they are worn below the manufacturer’s minimum thickness.
- Apply brake grease to the backing plates of the new pads.
- Reinstall the brake pads into the caliper.

4. Inspect Suspension Components

Sub-steps:
- Check for any play in the control arms, struts, and bushings.
- Replace any worn or damaged components as necessary.

5. Wheel Alignment and Balancing

Sub-steps:
- After all brake and suspension work is completed, take the vehicle to a professional alignment shop.
